No. III.


At A MEETING of The Royal society, Thursday, November 30th, 1753.

The President made a declaration of the prize-medal to be given this year by the Society in consequence of the legacy left by the late Sir Godfrey Copley, namely, that the Council of the Society, on whom the right of bestowing this prize was undoubtedly devolved by the death of Sir Hans Sloane, the surviving trustee named in Sir Godfrey's will, had nominated, for the same, Benjamin Franklin, Esquire, of Philadelphia, in Pennsylvania, on account of his curious experiments and observations on electricity.

In the declaring and bestowing which prize the President addressed himself to the Society in the following manner, here inserted at the express desire of the gentlemen present.


“Sir Hans Sloane being now dead, who was the surviving trustee of the late Sir Godfrey Copley, Baronet, the right of disposing of that gentleman's annual benefaction is incontestably devolved upon your President and Council, who have accordingly taken that matter into consideration.

“And, deliberating thereupon, they thought it their duty to keep these two points steadily in view, namely, the advancement of science and useful knowledge, and the honor of this Society. To the attaining both which ends they were convinced, that a strictly just and impartial disposal of this benefaction in favor of those only, who truly deserved it, would not a little conduce.

“Since such a disposition of it, if constantly practised, would greatly contribute to the credit of this Society, and at the same time would encourage laudable emulation among learned and ingenious men, who would thereby be induced to exert their functions, and endeavour to excel each other, not only in making useful and curious discoveries and improvements, but also in a

“Upon these principles your Council proceeded in fixing their choice of a person on whom this honorable mark of distinction should be this day conferred, and on such an occasion they could not overlook the merit of Benjamin Franklin, Esquire, of Pennsylvania; for, though he is not a Fellow of this Society, nor an inhabitant of this Island, he is a subject of the crown of Great Britain, and must be acknowledged to have deserved well of the philosophical world, and of this learned body in particular, to whom he has at various times caused to be communicated many of the experiments he has made, and of which you have lately received a large collection, together with the conclusions which he imagines may be deduced from them; all which are contained in his printed treatise upon the subject of electricity. A subject known in part, indeed, long ago, but which not many years since was thought to be of little importance, and was at that time only applied to illustrate in some degree the being and nature of attraction and repulsion; nor was anything worth much notice expected to ensue from it. “But, to the honor of this Society, and of the British nation in general, let it be remembered, that the person, who first attempted to explain the secrets of this then neglected subject, which now appears to have a most surprising share of power in nature, and who gave occasion to the diligent researches, that have since been made into the principles and essence of it, was a member of this Society, and a native and inhabitant of England, who, I am sorry to say, is now no more, since it must have given him inexpressible pleasure to see, that what he had done with respect to electricity had occasioned those great and important discoveries, which have now been made in relation thereto. “For not only his countrymen, but foreigners also, were incited by what he had discovered to make further experiments, and to push on with a becoming spirit their inquiries into the nature of this extraordinary phenomenon; and the indefatigable pains of a learned brother,” now present, were crowned with success even beyond expectation, and enabled him to make so considerable a progress in explaining and forming a kind of system of electricity, which now does and will continue to do him the greatest honor in all parts of the learned world. “I am persuaded, that it would offend this gentleman's modesty to hear, especially in this public manner, those commendations

which he justly deserves, and the high opinion which not only my-
self, but the whole Society, entertain of his uncommon skill and
abilities, as well in other branches of knowledge, as in this whereof
I have been speaking; for which reason I shall put a constraint
upon myself, and forbear entering into that encomium, which I
really think to be due to him.
“The advances, however, which this gentleman and others had
made towards laying open the nature of electricity, though very
considerable in themselves, left room for carrying on these inquiries
still further. To this work Mr. Franklin earnestly applied himself;
and, as his diligence and ingenuity deserved, so they met with, un-
common success. For, though some others might have begun to
entertain suspicions of an analogy between the effects of lightning
and electricity, yet I take Mr. Franklin to be the first, who, among
other curious discoveries, undertook to show from experiments, that
the former owed its origin entirely to the latter; and who pointed
out an easy method whereby any one might satisfy himself of the
truth of the fact, which he had so advanced.
“This method, which he had pointed out, was so much approved,
and has been so successfully put into execution in many different
places, that it remains no longer a matter of suspicion and doubt,
but is clear and plain to a demonstration, that electricity alone is
the cause of that tremendous appearance, whose effects prove fre-
quently so fatal in many parts of this terraqueous globe. And it
were greatly to be wished, that some effectual and practicable way
could be found by Mr. Franklin, or others, to prevent, or at least
to lessen, the mischiefs, which too often attend that terrible meteor.
“Mr. Franklin's book has for some time been in the hands of
most who hear me, and large accounts, drawn up by foreigners (as
well as by the learned gentleman before mentioned), of Mr. Frank-
lin's numerous and curious experiments, have been laid before this
Society, besides those which himself has more immediately caused
to be communicated to us at various times. It would therefore ke
impertinent in me to trespass upon your patience by entering into
a detail of particulars, which, I am satisfied, you are all well ac-
quainted with.
“True it is, that several learned men, both at home and abroad,
do not entirely agree with him in all the conclusions, which he
thinks may be deduced from the experiments he has made. But
far be it from me to pretend to decide these points, more especially
in this place and at this time. That matter is yet in dispute; and,
if I am rightly informed, Mr. Franklin is now preparing to produce

in support of his sentiments still farther experiments, some of which, he flatters himself, will appear more surprising than any that have already been communicated to the world. “Let it therefore suffice for the present to say, that even those persons, who happen to differ from him in opinion as to some points, universally acknowledge his great merit, and particularly the learned gentleman, whom I have more than once mentioned, is pleased to declare Mr. Franklin to be “a very able and ingenious man,’ and says, “that he has a head to conceive, and a hand to carry into execution, whatever he thinks may conduce to enlighten the subject-matter of which he is treating;' and, although that gentleman “cannot agree with him in some of his opinions, yet he thinks scarce anybody better acquainted with the subject of electricity than Mr. Franklin.” These testimonials, therefore, given by so capable as well as unprejudiced judges, in his favor, and more especially that character of him, which I have just quoted, joined with that opinion, which every one who has read his books must entertain of him, will sufficiently justify your Council in having adjudged to Mr. Franklin the Copley medal for this year, as a mark of distinction due to his unquestionable merit. “Many and very considerable advantages and improvements have, within the space of some years past, been made in several branches of natural knowledge; but there is ample room still remaining for the inquisitive and able philosopher to employ his skill and labor. The Book of Nature is a very huge and comprehensive volume; and, notwithstanding no small part of it has been unfolded and exposed to our view by learned and ingenious men of this and many other countries, yet it still contains abundantly sufficient matter to exercise our talents upon, and which justly ought to excite our curiosity, and encourage us to proceed with vigor in our endeavours to bring to light what is at present concealed from our eyes. We know that few things are of so occult and obstinate a nature, as not to yield to sagacity, and to be forced to lay open their most hidden properties to the diligent and inquisitive inquirer. “In confidence whereof let us pursue, with unwearied application and assiduity, our researches into every branch of natural philosophy. Nor let us be discouraged from such pursuits by a mistaken notion, that any part of it is too inconsiderable to deserve our regard and attention; since who could have entertained any hopes, some years ago, that electricity was capable of furnishing matter for so great and important discoveries, as have lately been made in relation thereto, and which at this time afford us a promising pros
