11To Benjamin Franklin from Cadwallader Colden, [February 1746] (Franklin Papers)
Draft: New-York Historical Society There is no Question but in the case you mention of a ships being taken up in a Southern latitude and let down in one some degrees more northerly the same moment she would have a degree of Motion Eastward but that it would shorten a Voyage from America to Europe I cannot think because as the alteration is made by insensibly small steps it can only be so much...

16To Benjamin Franklin from Cadwallader Colden, 3 August 1747 (Franklin Papers)
ALS : New-York Historical Society Baxters [book] was gon so much out of my memory that I could not for some time recollect any thing of it.

17From Benjamin Franklin to Cadwallader Colden, 6 August 1747 (Franklin Papers)
ALS : New-York Historical Society; draft: American Philosophical Society The Observations I sent you on Baxter’s Book were wrote on a Sheet or two of Paper in Folio.

If I succeeded, all his Edifice falls of course, unless some other way...
