Memoirs of Benjamin Franklin; Written by Himself. [Vol. 1 of 2]

About a month before this period, some ingenious Frenchman had completed the discovery in the manner originally proposed by Dr. Franklin. The letters which he sent to Mr. Collinson, it is said, were refused a place in the Transactions of the Royal Society of London. However this may be, Collinson published them in a separate volume, under the title of "New Experiments and Observations on Electricity, made at Philadelphia, in America." They were read with avidity, and soon translated into different languages. A very incorrect French translation fell into the hands of the celebrated Buffon, who, notwithstanding the disadvantages under which the work laboured, was much pleased with it, and repeated the experiments with success. He prevailed on his friend, M. D'Alibard, to give his countrymen a more correct translation of the works of the American electrician. This contributed much towards spreading a knowledge of Franklin's principles in France. The king, Louis XV., hearing of these experiments, expressed a wish to be a spectator of them. A course of experiments was given at the seat of the Duc D'Ayen, at St. Germain, by M. de Lor. The applauses which the king bestowed upon Franklin excited in Buffon, D'Alibard, and De Lor, an earnest desire of ascertaining the truth of his theory of thunder-gust. Buffon erected his apparatus on the tower of Monthar, M. D'Alibard at Mary-la-ville, and De Lor at his house in the Estrapade at Paris, some of the highest ground in that capital. D'Alibard's machine first showed signs of electricity. On the 10th of May, 1752, a thunder-cloud passed it, in the absence of M'Alibard, and a number of sparks were drawn from it by Coiffier, a joiner, with whom D'Alibard had left directions how to proceed, and by M. Raulet the prior of Mary-la-ville. An account of this experiment was given to the Royal Academy of Sciences, by M. D'Alibard, in a memoir, dated May 13, 1752. On the 18th of May, M. de Lor proved equally successful with the apparatus erected at his own house. These philosophers soon excited those of other parts of Europe to repeat the experiment, among whom none signalized themselves more than Father Beccaria, of Turin, to whose observations science is much indebted. Even the cold regions of Russia were penetrated by the ardour for discovery. Professor Richman bade fair to add much to the stock of knowledge on this subject, when an unfortunate flash from his conductor put a period to his existence. The friends of science will long remember with regret the amiable martyr to electricity.

By these experiments Franklin's theory was established in the most convincing manner. When the truth of it could no longer be doubted, envy and vanity endeavoured to detract from its merit. That an American, an inhabitant of the obscure city of Philadelphia, the name of which was hardly known, should be able to make discoveries and to frame theories which had escaped the notice of the enlightened philosophers of Europe, was too mortifying to be admitted. He must certainly have taken the idea from some one else. An American, a being of an inferior order, make discoveries! Impossible. It was said that the Abbé Nollet, 1748, had suggested the idea of the similarity of lightning and electricity in his Leçons de Physique. It is true that the abbé mentions the idea, but he throws it out as a bare conjecture, and proposes no mode of ascertaining the truth of it. He himself acknowledges that Franklin first entertained the bold thought of bringing lightning from the heavens, by means of pointed rods fixed in the air. The similarity of lightning and electricity is so strong, that we need not be surprised at notice being taken of it as soon as electrical phenomena became familiar. We find it mentioned by Dr. Wall and Mr. Grey, while the science was in its infancy. But the honor of forming a regular theory of thunder-gusts, of suggesting a mode of determining the truth of it by experiments, and of putting these experiments in practice, and thus establishing the theory upon a firm and solid basis, is incontestibly due to Franklin. D'Alibard, who made the first experiments in France, says that he only followed the tract which Franklin had pointed out.

It has been of late asserted, that the honour of completing the experiment with the electrical kite does not belong to Franklin. Some late English paragraphs have attributed it to some Frenchman, whose name they do not mention: and the Abbé Bertholon gives it to M. de Romas, assessor to the presideal of Nerac: the English paragraphs probably refer to the same person. But a very slight attention will convince us of the injustice of this procedure: Dr. Franklin's experiment was made in June, 1752, and his letter, giving an account of it, is dated October 19, 1752. M. de Romas made his first attempt on the 14th of May, 1753, but was not successful until the 7th of June, a year after Franklin had completed the discovery, and when it was known to all the philosophers in Europe.

Besides these great principles, Franklin's letters on electricity contain a number of facts and hints which have contributed greatly towards reducing this branch of knowledge to a science. His friend, Mr. Kinnersley, communicated to him a discovery of the different kinds of electricity, excited by rubbing glass and sulphur. This, we have said, was first observed by M. du Faye, but it was for many years neglected. The philosophers were disposed to account for the phenomena rather from a difference in the quantity of electricity collected, and even Du Faye himself seems at last to have adopted this doctrine. Franklin at first entertained the same idea; but, upon repeating the experiment, he perceived that Mr. Kinnersley was right; and that the vitreous and resinous electricity of Du Faye were nothing more than the positive and negative states which he had before observed; and that the glass globe charged positively, or increased the quantity of electricity on the prime conductor, while the globe of sulphur diminishes its natural quantity, or charged negatively. These experiments and observations opened a new field for investigation, upon which electricians entered with avidity, and their labours have added much to the stock of our knowledge.

In September, 1752, Franklin entered upon a course of experiments to determine the state of electricity in the clouds. From a number of experiments he formed this conclusion: "That the clouds of a thunder-gust are most commonly in a negative state of electricity, but sometimes in a positive state;" and from this it follows, as a necessary consequence, "that, for the most part, in thunder-strokes, it is the earth that strikes into the clouds, and not the clouds that strike into the earth." The letter containing these observations is dated in September, 1753; and yet the discovery of ascending thunder has been said to be of a modern date, and has been attributed to the Abbé Bertholon, who published his memoir on the subject in 1776.

Franklin's letters have been translated into most of the European languages and into Latin. In proportion as they have become known, his principles have been adopted. Some opposition was made to his theories, particularly by the Abbé Nollet, who was, however, feebly supported, while the first philosophers in Europe stepped forth in defence of Franklin's principles, among whom D'Alibard and Beccaria were the most distinguished. The opposition has gradually ceased, and the Franklinian system is now universally adopted where science flourishes.

The important practical use which Franklin made of his discoveries, the securing of houses from injury by lightning, has been already mentioned. Pointed conductors are now very common in America; but prejudice has hitherto prevented their general introduction into Europe, notwithstanding the most undoubted proofs of their utility have been given. But mankind can with difficulty be brought to lay aside established practices, or to adopt new ones. And perhaps we have more reason to be surprised that a practice, however rational, which was proposed about forty years ago, should in that time have been adopted in so many places, than that it has not universally prevailed. It is only by degrees that the great body of mankind can be led into new practices, however salutary their tendency. It is now nearly eighty years since inoculation was introduced into Europe and America; and it is so far from being general at present, that it will require one or two centuries to render it so.

The disputes between the proprietaries and the people of the province continued in full force, although a war was raging on the frontiers. Not even the sense of danger was sufficient to reconcile, for ever so short a time, their jarring interests. The Assembly still insisted upon the justice of taxing the proprietary estates; but the governors constantly refused their assent to this measure, without which no bill could pass into a law. Enraged at the obstinacy, and what they conceived to be the unjust proceedings of their opponents, the Assembly at length determined to apply to the mother country for relief. A petition was addressed to the king in council, stating the inconveniences under which the inhabitants laboured, from the attention of the proprietaries to their private interest, to the neglect of the general welfare of the community, and praying for redress. Franklin was appointed to present this address, as agent for the province of Pennsylvania, and departed from America in June, 1757. In conformity to the instructions which he had received from the legislature, he held a conference with the proprietaries who then resided in England, and endeavoured to prevail upon them to give up the long-contested point. Finding that they would hearken to no terms of accommodation, he laid his petition before the council. During this time Governor Denny assented to a law imposing a tax, in which no discrimination was made in favour of the estates of the Penn family. They, alarmed at this intelligence and Franklin's exertions, used their utmost endeavours to prevent the royal sanction being given to this law, which they represented as highly iniquitous, designed to throw the burden of supporting government upon them, and calculated to produce the most ruinous consequences to them and their posterity. The cause was amply discussed before the privy council. The Penns found here some strenuous advocates; nor were there wanting some who warmly espoused the side of the people. After some time spent in debate, a proposal was made that Franklin should solemnly engage that the assessment of the tax should be so made as that the proprietary estates should pay no more than a due proportion. This he agreed to perform, the Penn family withdrew their opposition, and tranquillity was thus once more restored to the province.

The mode in which this dispute was terminated is a striking proof of the high opinion entertained of Franklin's integrity and honour, even by those who considered him as inimical to their views. Nor was their confidence ill-founded. The assessment was made upon the strictest principle of equity; and the proprietary estates bore only a proportionable share of the expenses of supporting government.

After the completion of this important business, Franklin remained at the court of Great Britain as agent for the province of Pennsylvania. The extensive knowledge which he possessed of the situation of the colonies, and the regard which he always manifested for their interests, occasioned his appointment to the same office by the colonies of Massachusetts, Maryland, and Georgia. His conduct, in this situation, was such as rendered him still more dear to his countrymen.

He had now an opportunity of indulging in the society of those friends whom his merits had procured him while at a distance. The regard which they had entertained for him was rather increased by a personal acquaintance. The opposition which had been made to his discoveries in philosophy gradually ceased, and the rewards of literary merit were abundantly conferred upon him. The Royal Society of London, which had at first refused his performances admission into its transactions, now thought it an honour to rank him among its fellows. Other societies of Europe were equally ambitious of calling him a member. The University of St. Andrew, in Scotland, conferred upon him the degree of Doctor of Laws. Its example was followed by the Universities of Edinburgh and Oxford. His correspondence was sought for by the most eminent philosophers of Europe. His letters to these abound with true science, delivered in the most simple, unadorned manner.

The province of Canada was at this time in the possession of the French, who had originally settled it. The trade with the Indians, for which its situation was very convenient, was exceedingly lucrative. The French traders here found a market for their commodities, and received in return large quantities of rich furs, which they disposed of at a high price in Europe. While the possession of this country was highly advantageous to France, it was a grievous inconvenience to the inhabitants of the British colonies. The Indians were almost generally desirous to cultivate the friendship of the French, by whom they were abundantly supplied with arms and ammunition. Whenever a war happened, the Indians were ready to fall upon the frontiers; and this they frequently did, even when Great Britain and France were at peace. From these considerations, it appeared to be the interest of Great Britain to gain the possession of Canada. But the importance of such an acquisition was not well understood in England. Franklin about this time published his Canada pamphlet, in which he, in a very forcible manner, pointed out the advantages which would result from the conquest of this province.

An expedition against it was planned, and the command given to General Wolfe. His success is well known. At the treaty in 1762, France ceded Canada to Great Britain; and by her cession of Louisiana, at the same time, relinquished all her possessions on the continent of America.

Although Dr. Franklin was now principally occupied with political pursuits, he found time for philosophical studies. He extended his electrical researches, and made a variety of experiments, particularly on the tourmalin. The singular properties which this stone possesses, of being electrified on one side positively, and on the other negatively, by heat alone, without friction, had been but lately observed.

Some experiments on the cold produced by evaporation, made by Dr. Cullen, had been communicated to Dr. Franklin by Professor Simpson, of Glasgow. These he repeated, and found that, by the evaporation of ether in the exhausted receiver of an airpump, so great a degree of cold was produced in a summer's day, that water was converted into ice. This discovery he applied to the solution of a number of phenomena, particularly a single fact, which philosophers had endeavoured in vain to account for, viz., that the temperature of the human body, when in health, never exceeds 96 degrees of Fahrenheit's thermometer, although the atmosphere which surrounds it may be heated to a much greater degree. This he attributed to the increased perspiration and consequent evaporation produced by the heat.

In a letter to Mr. Small, of London, dated in May, 1760, Dr. Franklin makes a number of observations, tending to show that, in North America, northeast storms begin in the southwest parts. It appears, from actual observations, that a northeast storm, which extended a considerable distance, commenced at Philadelphia nearly four hours before it was felt at Boston. He endeavoured to account for this by supposing that, from heat, some rarefication takes place about the Gulf of Mexico; that the air farther north, being cooler, rushes in, and is succeeded by the cooler and denser air still farther north, and that thus a continued current is at length produced.

The tone produced by rubbing the brim of a drinking-glass with a wet finger had been generally known. A Mr. Puckeridge, an Irishman, by placing on a table a number of glasses of different sizes, and tuning them, by partly filling them with water, endeavoured to form an instrument capable of playing tunes. He was prevented, by an untimely end, from bringing his invention to any degree of perfection. After his death some improvements were made upon his plan. The sweetness of the tones induced Dr. Franklin to make a variety of experiments; and he at length formed that elegant instrument which he has called the Armonica.

In the summer of 1762 he returned to America. On his passage he observed the singular effect produced by the agitation of a vessel containing oil floating on water. The surface of the oil remains smooth and undisturbed, while the water is agitated with the utmost commotion. No satisfactory explanation of this appearance has, we believe, ever been given.

Dr. Franklin received the thanks of the Assembly of Pennsylvania, "as well for the faithful discharge of his duty to that province in particular, as for the many and important services done to America in general during his residence in Great Britain." A compensation of 5000l., Pennsylvania currency, was also decreed him for his service during six years.

During his absence he had been annually elected member of the Assembly. On his return to Pennsylvania he again took his seat in this body, and continued a steady defender of the liberties of the people.

In December, 1762, a circumstance which caused great alarm in the province took place. A number of Indians had resided in the county of Lancaster, and conducted themselves uniformly as friends to the white inhabitants. Repeated depredations on the frontiers had exasperated the inhabitants to such a degree, that they determined on revenge upon every Indian. A number of persons, to the amount of about 120, principally inhabitants of Donegal and Peckstang, or Paxton, townships, in the county of York, assembled, and, mounted on horseback, proceeded to the settlement of these harmless and defenceless Indians, whose number had now been reduced to about twenty. The Indians received intelligence of the attack which was intended against them, but disbelieved it. Considering the white people as their friends, they apprehended no danger from them. When the party arrived at the Indian settlement, they found only some women and children, and a few old men, the rest being absent at work. They murdered all whom they found, and among others the chief Shaheas, who had been always distinguished for his friendship to the whites. This bloody deed excited much indignation in the well-disposed part of the community.

The remainder of these unfortunate Indians, who, by absence, had escaped the massacre, were conducted to Lancaster, and lodged in the jail as a place of security. The governor issued a proclamation, expressing the strongest disapprobation of the action, offering a reward for the discovery of the perpetrators of the deed, and prohibiting all injuries to the peaceable Indians in future. But, notwithstanding this, a party of the same men shortly after marched to Lancaster, broke open the jail, and inhumanly butchered the innocent Indians who had been placed there for security. Another proclamation was issued, but it had no effect. A detachment marched down to Philadelphia for the express purpose of murdering some friendly Indians, who had been removed to the city for safety. A number of the citizens armed in their defence. The Quakers, whose principles are opposed to fighting, even in their own defence, were most active upon this occasion. The rioters came to Germantown. The governor fled for safety to the house of Dr. Franklin, who, with some others, advanced to meet the Paxton boys, as they were called, and had influence enough to prevail upon them to relinquish their undertaking and return to their homes.

The disputes between the proprietaries and the Assembly, which for a time had subsided, were again revived. The proprietaries were dissatisfied with the concessions made in favour of the people, and made great struggles to recover the privilege of exempting their estates from taxation, which they had been induced to give up.

In 1763 the Assembly passed a militia bill, to which the governor refused to give his assent, unless the Assembly would agree to certain amendments which he proposed. These consisted in increasing the fines, and, in some cases, substituting death for fines. He wished, too, that the officers should be appointed altogether by himself, and not be nominated by the people, as the bill had proposed. These amendments the Assembly considered as inconsistent with the spirit of liberty. They would not adopt them; the governor was obstinate, and the bill was lost.

These, and various other circumstances, increased the uneasiness which subsisted between the proprietaries and the Assembly, to such a degree that, in 1764, a petition to the king was agreed to by the house, praying an alteration from a proprietary to a regal government. Great opposition was made to this measure, not only in the house, but in the public prints. A speech of Mr. Dickenson on the subject was published, with a preface by Dr. Smith, in which great pains were taken to show the impropriety and impolicy of this proceeding. A speech of Mr. Golloway, in reply to Mr. Dickenson, was published, accompanied with a preface by Dr. Franklin, in which he ably opposed the principles laid down in the preface to Mr. Dickenson's speech. This application to the throne produced no effect. The proprietary government was still continued.

At the election for a new Assembly, in the fall of 1764, the friends of the proprietaries made great exertions to exclude those of the adverse party; and they obtained a small majority in the city of Philadelphia. Franklin now lost his seat in the house, which he had held for fourteen years. On the meeting of the Assembly it appeared that there was still a decided majority of Franklin's friends. He was immediately appointed provincial agent, to the great chagrin of his enemies, who made a solemn protest against this appointment: which was refused admission upon the minutes, as being unprecedented. It was, however, published in the papers, and produced a spirited reply from him, just before his departure for England.

The disturbances produced in America by Mr. Grenville's stamp-act, and the opposition made to it, are well known. Under the Marquis of Rockingham's administration, it appeared expedient to endeavour to calm the minds of the colonists, and the repeal of the odious tax was contemplated. Among other means of collecting information on the disposition of the people to submit to it, Dr. Franklin was called to the bar of the House of Commons. The examination which he here underwent was published, and contains a striking proof of the extent and accuracy of his information, and the facility with which he communicated his sentiments. He represented facts in so strong a point of view, that the expediency of the act must have appeared clear to every unprejudiced mind. The act, after some opposition, was repealed, about a year after it was enacted, and before it had ever been carried into execution.

In the year 1766, he made a visit to Holland and Germany, and received the greatest marks of attention from men of science. In his passage through Holland, he learned from the watermen the effect which a diminution of the quantity of water in canals has in impeding the progress of boats. Upon his return to England, he was led to make a number of experiments, all of which tended to confirm the observation. These, with an explanation of the phenomenon, he communicated in a letter to his friend, Sir John Pringle, which is among his philosophical pieces.

In the following year he travelled into France, where he met with a no less favourable reception than he had experienced in Germany. He was introduced to a number of literary characters, and to the king, Louis XV.

Several letters, written by Hutchinson, Oliver, and others, to persons in eminent stations in Great Britain, came into the hands of Dr. Franklin. These contained the most violent invectives against the leading characters of the State of Massachusetts, and strenuously advised the prosecution of vigorous measures to compel the people to obedience to the measures of the ministry. These he transmitted to the legislature, by whom they were published. Attested copies of them were sent to Great Britain, with an address, praying the king to discharge from office persons who had rendered themselves obnoxious to the people, and who had shown themselves so unfriendly to their interests. The publication of these letters produced a duel between Mr. Whately and Mr. Temple; each of whom was suspected of having been instrumental in procuring them. To prevent any farther disputes on this subject, Dr. Franklin, in one of the public papers, declared that he had sent them to America, but would give no information concerning the manner in which he had obtained them; nor was this ever discovered.
