1To Benjamin Franklin from Jan Ingenhousz, 15 November 1776 (Franklin Papers)
ALS : American Philosophical Society; duplicate: Staatsbibliothek Preussischer Kulturbesitz, West Berlin Since I received your kind lettre dated Marsch 18, 1774, great things have happened, of which your country is the theatre. That country is become the seat of horror and bloodshed, which I took to be the seat of tranquillity and happiness, and which I was formerly much inclined to chuse as a...

ALS : American Philosophical Society A little time ago I sent you a lettre by the way of London in hopes it should soon Come to your hands in America.

5To Benjamin Franklin from Jan Ingenhousz, 28 June 1777 (Franklin Papers)
ALS : American Philosophical Society It seems all your lettres miscarry in a certain way. Your last favour of the 26 of April came only to my hands a few days ago after having passed thro Vienna and a great part of the German Empire. I am still at Tissingen in Suabia upon the estate of the Prince de la Tour et Tassis , whose two sons I have succesfully inoculated. I intend to set out from here...

7To Benjamin Franklin from Jan Ingenhousz, 30 August 1777 (Franklin Papers)
ALS : American Philosophical Society I found a coach, very easy and very strong, which can keep 4 persons. The bargain, which I was able to make, is to pay 9 livres a day till the 18th and than 6 Livres a day afterwards. Thus if we stay on our journey 16 days, it will cost us only 6 louis d’ors. I am sure it will be impossible to meet with a more reasonnable bargain, as commonly I am assured a...
