1From Thomas Jefferson to John Vaughan, 24 June 1806 (Jefferson Papers)
I recieved last night your favor of the 20th. and I now inclose you Capt Elwood’s reciept for both boxes. the servant who carried them to the vessel says that the light box was put into the cabin (this is the one you have recieved,) & the heavy one into the hold, where it has perhaps been overlooked & may be yet found. this contained the Louisiana minerals. I recieved by post the books you...
2From Thomas Jefferson to John Vaughan, 15 April 1806 (Jefferson Papers)
On recurring to my letter of Jan. 14. I find that though the remittance I then troubled you with was intended to include, with the newspapers there mentioned, mr Poulson’s Daily Advertiser, yet I omitted to enumerate it. I will therefore pray you to discharge my arrears to him, which to the 1st. day of the present year amount to 18.D. which the sum remaining will just cover. pardon the trouble...

I send you for the use of the Philosophical society a copy of my communications to Congress of the information respecting Louisiana which we have recieved through Capt. Lewis, Mr. Dunbar & Doctr.

5From Thomas Jefferson to John Vaughan, 8 September 1807 (Jefferson Papers)
Th: Jefferson presents his thanks to mr Vaughan for the communication of M. Lippi’s pamphlet. it is certainly a remarkable instance of the passion of vanity keeping full pace with the degree of science inspiring it. one would hardly expect in a mind exhibiting so much strength to find a weakness so little indicative of it. he returns the pamphlet to mr Vaughan with his friendly salutations....

7From Thomas Jefferson to John Vaughan, 5 November 1801 (Jefferson Papers)
I recieved on the 24th. Ult. your favor of the 22d. but it is not till this day that I am enabled to comply with your request of forwarding some of the vaccine matter for Doctr.

8From Thomas Jefferson to John Vaughan, 4 May 1806 (Jefferson Papers)
Being near my departure for Monticello I leave here with orders to forward them to you by the first vessel, a box containing the minerals from Capt. Lewis which were the subject of a former letter, & another containing an instrument called a Bathometer sent to me by it’s inventor. believing it cannot be otherwise so well disposed of, I beg leave to deposit it with the Philosophical society...
9From Thomas Jefferson to John Vaughan, 15 August 1805 (Jefferson Papers)
I now return you the inclosed with many thanks for the opportunity of perusing it, which I have done with great satisfaction. I had before observed that Faujas & Cuvier were rather at war. Cuvier is attached to artificial classification. Faujas thinks with Buffon that the number of Quadrupeds is too small to need it, and that it is better to groupe them as individually according to more...

I recieved last night your favor of the 19th. and with it the pamphlet of Naval architecture for which I thank you. it may be of use in our navy office where I shall deposit it. I am extremely glad to hear that the infection from the vaccine matter I sent has succeeded. but my great anxiety now is to know whether it prevents the small pox: and my anxiety arises not from any doubt that it would...
