Benjamin Franklin to Cadwallader Colden, July 30, 1747

Philada. July 30. 1747

Sir

I receiv’d your Favour of the 26th. 4 which I shall answer at large per next Post. In the mean time please to send me, if you have it with you, my Paper of Observations on Baxter’s Book, which I want to make some present Use of, and have no other Copy. 5

Mesnard sail’d this Day for London. But here is a Vessel bound to Bristol, which the next Post will reach. In haste I am, Sir Your oblig’d humble Servant

B Franklin

P S . Upon farther Enquiry I find that next Post will not reach the Bristol Vessel, she being to sail on Saturday. 6
