743From 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...

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...

746From Benjamin Franklin to Peter Collinson, 14 August 1747 (Franklin Papers)
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...

748From Benjamin Franklin to Peter Collinson, 24 September 1764 (Franklin Papers)
ALS : Pierpont Morgan Library I received your kind Letter of June 29. We hear nothing here of the Proprietary”s relenting.

A few Days will settle this...

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...
