1From 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.

2From 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.

3From Benjamin Franklin to Peter Collinson, 1753 (Franklin Papers)
Transcript: Historical Society of Pennsylvania With regard to the Germans, I think Methods of great tenderness should be used, and nothing that looks like a hardship be imposed.

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...
