21From Benjamin Franklin to Peter Collinson, September 1753 (Franklin Papers)
Copy: Massachusetts Historical Society In my former Paper on this Subject, wrote first in 1747, enlarged and sent to England in 1749, I considered the Sea as the grand source of Lightning, imagining its luminous Appearance to be owing to Electric Fire, produced by Friction between the Particles of Water and those of Salt. Living far from the Sea I had then no opportunity of making Experiments...
22From Benjamin Franklin to Peter Collinson, 23 November 1753 (Franklin Papers)
MS not found; reprinted from Benjamin Franklin, Experiments and Observations on Electricity (London, 1769), p. 165. In my last, via Virginia, I promised to send you per next ship, a small philosophical pacquet: But now having got the materials (old letters and rough drafts) before me, I fear you will find it a great one. Nevertheless, as I am like to have a few days leisure before this ship...
23From Benjamin Franklin to Peter Collinson, 18 April 1754 (Franklin Papers)
Copy: New-York Historical Society Since September last, having been abroad on two long Journeys, and otherwise much engag’d, I have made but few Observations on the positive and negative State of Electricity in the Clouds. But Mr. Kinnersley kept his Rod and Bells in good Order, and has made many. Once this Winter the Bells rang a long time during a fall of Snow, tho’ no Thunder was heard nor...
24From Benjamin Franklin to Peter Collinson, 28 May 1754 (Franklin Papers)
Copy: American Philosophical Society I had at length the pleasure of hearing from you per the Myrtilla that brought me yours of the 26th. Janry. with which I received the two Cases containing the Maps, Silk &c. all very agreeable: but nothing more so than the good News you tell me, that our Proprietor is solicitous for the Prosperity of the Academy, has ordered a Salary towards the Support of...
25From Benjamin Franklin to Peter Collinson, 29 July 1754 (Franklin Papers)
ALS : American Philosophical Society I am just return’d from Albany, where were Commissioners from seven Provinces to treat with the Indians of the Six Nations. I suppose the Treaty will be printed, and I shall send you a Copy. At present can only mention, that we brighten’d the Chain with them &c. and parted good Friends; but in my Opinion no Assistance is to be expected from them in any...

27Deborah Franklin to Peter Collinson, 30 April 1755 (Franklin Papers)
LS : Huntington Library Mr. Franklin is from home, and can not have by this Conveyance an Opportunity of answering your Favours by the last Ships. I have forwarded your Letters to Mr. Elliot, Mr. Bartram, Mr. Barton and Mr. Franklin. My Husband is now in the Back Counties, contracting for some Waggons and Horses for the Army, which tho’ so much out of his Way, he was obliged to undertake, for...
28From Benjamin Franklin to Peter Collinson, 26 June 1755 (Franklin Papers)
ALS : Pierpont Morgan Library Mr. Bartram brings a Box to my House, which has a little Vacancy in it; so I put in my Philosophical Pacquet, which I long since intended to send you, but one thing or other has prevented. I would not have any Part of it printed, (unless you should think that printing the Papers relating to Whirlwinds and Water Spouts, together with a Collection of all the...
29From Benjamin Franklin to Peter Collinson, 25 August 1755 (Franklin Papers)
MS not found; reprinted from Benjamin Franklin, Experiments and Observations on Electricity (London, 1769), pp. 356–9. As you have my former papers on Whirlwinds, &c.

Tasker, and some other gentlemen to his country-seat, where I and my son were entertained by...
30From Benjamin Franklin to Peter Collinson, 27 August 1755 (Franklin Papers)
ALS : Pierpont Morgan Library I received your Favours of May 28 and June 1. I believe I have already wrote you, that our Friend Smith is not thought here to be the Author of the Pamphlet you mention: ’Tis generally suppos’d to be the Governor’s (with some help from one or two others) as his Messages are fill’d with the same Sentiments and almost the same Expressions. He is, I think, the...
