Your favor of the 12 th is recieved and also the Nautical Almanacs for 1811. 12. for which accept my thanks as well as for the artificial horizon proposed to be forwarded. as it would be liable to be broken, it would come best by some of the vessels sailing daily from Philadelphia to Richmond addressed to me to the care of Mess rs Gibson & Jefferson merchants at Richmond , adding ‘ to be...

3Thomas Jefferson to Robert Patterson, 10 November 1811 (Jefferson Papers)
Your favor of Sep. 23. came to hand in due time, and I thank you for the Nautical almanac it covered for the year 1813. I learn with pleasure that the Philosophical society has concluded to take into consideration the subject of a fixed standard of measures weights and coins; and you ask my ideas on it; insulated as my situation is, I am sure I can offer nothing but what will occur to the...
4Thomas Jefferson to Robert Patterson, 27 December 1812 (Jefferson Papers)
After an absence of five weeks at a distant possession of mine to which I pay such visits three or four times a year, I find here your favor of Nov. 30. I am very thankful to you for the description of Redhefer’s machine. I had never before been able to form an idea what his principle of deception was. he is the first of the inventors of perpetual motion, within my knolege, who has had the...

At the request of mr Warden I transmit to the A. Philosophical society an Analysis of tobacco by M. Vauquelin , translated by mr Warden .

6Thomas Jefferson to Robert Patterson, 7 March 1811 (Jefferson Papers)
I had thought that the copies of the Nautical Almanac which you had been so kind as to furnish me with some time ago, had included the present year, till I had occasion to use one, and found myself mistaken. having no other medium of obtaining it at present this moment, I have indulged myself with the hope that your friendship would permit me to ask the favor of you to send me that of the...
7Thomas Jefferson to Robert Patterson, 29 May 1812 (Jefferson Papers)
It is long since any occasion presented itself of addressing a letter to you. I avail myself with pleasure therefore of that offered by the papers I now inclose you. they were intended for the society as I judge from the superscription. a long journey soon after their reciept from which I am but just returned, prevented my earlier transmission of them. I was very sensible of the solidity of...
8Thomas Jefferson to Robert Patterson, 9 August 1812 (Jefferson Papers)
I send you another paper from our indefatigable calculator William Lambert . I do not know whether he is a member of our society, but I think his assiduities and qualifications render him entirely worthy of the choice of the society. our literary fare must be of homespun materials, I presume, during the continuance of the war, except so far as we may be refreshed by the precarious reciept of...

10Thomas Jefferson to Robert Patterson, 11 September 1811 (Jefferson Papers)
The inclosed work came to me without a scrip of a pen other than what you see in the title page. ‘A Mons r le president de la societé.’ from this I conclude it intended for the Philosophical society , & for them I now inclose it to you. you will find the notes really of value. they embody and ascertain to us all the scraps of new discoveries which we have learnt in detached articles, from less...
