MS not found; reprinted from extract in Benjamin Franklin, Experiments and Observations on Electricity (London, 1769), pp. 1–2. This is the earliest surviving letter in which Franklin alludes to his electrical investigations. It introduced the fourth edition of his Experiments and Observations in 1769. That edition, its predecessors and its successor, will be discussed below, under their...
Copy: American Academy of Arts and Sciences In my last I informed you that In pursuing our Electrical Enquiries, we had observ’d some particular Phaenomena, which we lookt upon to be new, and of which I promised to give you some Account; tho’ I apprehended they might possibly not be new to you, as so many Hands are daily employed in Electrical Experiments on your Side the Water, some or other...
Copy: American Academy of Arts and Sciences The inclosed is a Copy of my last, which went by the Governour’s Vessel: since which we have received, by Mesnard and Ouchterlony, Hill’s Theophrastus, Pemberton’s Dispensatory, Wilson’s Electricity and some other Pamphlets. The Proprietor’s handsome Present of a complete Electrical Apparatus &c. is also come to Hand in good Order, and is put up in...
ALS : Pierpont Morgan Library I have lately written two long Letters to you on the Subject of Electricity, one by the Governor’s Vessel, the other per Mesnard. On some further Experiments since, I have observ’d a Phenomenon or two that I cannot at present account for on the Principles laid down in those Letters, and am therefore become a little diffident of my Hypothesis, and asham’d that I...
ALS : Pierpont Morgan Library I have receiv’d your several Favours of April 1. June 2. June 14 and Augt. 20, and some others, with all the Books and Pamphlets you have sent at sundry Times for the Library Company: We wish it were in our Power to do you or any Friend of yours some Service in Return for your long-continued Kindness to us. I am pleas’d to hear that my Electrical Experiments were...
Copy: American Academy of Arts and Sciences I now send you some Further Experiments and Observations in Electricity made in Philadelphia 1748. viz. §1. There will be the same Explosion and Shock if the electrified, Phial is held in one Hand by the Hook, and the Coating touched by the other; as when held by the Coating and touched at the Hook. §2. To take the charged Phial safely by the Hook,...
MS not found; reprinted from The Gentleman’s Magazine , XX (1750), 208. I was very much pleased with some ingenious papers in the late Transactions on the subject of electricity. There is something however in the experiments of points, sending off, or drawing on, the electrical fire, which has not been fully explained, and which I intend to supply in my next. For the doctrine of points is very...
Copy: American Academy of Arts and Sciences Mr. Watson I believe wrote his Observations on my last Paper in Haste; without having first well considered the Experiments related in §17 *Of the third Letter. which still appear to me decisive in the Question; Whether the Accumulation of Electrical Fire be in the Electrified Glass, or in the Non-electric Matter connected with the Glass? and to...
Copy: American Academy of Arts and Sciences As you first put us on Electrical Experiments by sending to our Library-Company a Tube with Directions how to use it; and as our honourable Proprietor enabled us to carry those Experiments to a greater Height, by his generous Present of a complete Electrical Apparatus; ’Tis fit that both should know from Time to Time what Progress we make. It was in...
ALS : The Royal Society I receiv’d yours of Oct. 4. via New England, with the Account of what you have laid out on Books and Mathematical Instruments for the Academy, by which I perceive there is but about £20 in your Hands, much too little, I fear, for the Philosophical Apparatus! and the Misfortune is, that our other Expences in purchasing, Building, &c. are like to pinch us so in the...
