1Thomas Jefferson to Peter S. Du Ponceau, 7 July 1820 (Jefferson Papers)
I have lately had an opportunity of procuring a copy of a Vocabulary of the Nottoway tribe of Indians . these with the Pamunkies and Mattaponies were component parts of the great Powhatan confederacy which covered all the lower part of this state , and probably spoke the general language of the Powhatans. this vocabulary was taken by mr John Wood formerly professor of mathematics in W m & Mary...
2Thomas Jefferson to Peter S. Du Ponceau, 31 March 1821 (Jefferson Papers)
Your favor of the 23 d is recieved. the acquaintance I had the pleasure of forming with mr Vanuxem while he favored me with a visit gave me a very high sense of his merit and qualifications. in addition to this your recommendations and those of D r Cooper place him on very high ground but I fear we are as yet far from the time at which we may turn our attention to the choice of Professors. our...

4Thomas Jefferson to Peter S. Du Ponceau, 6 November 1817 (Jefferson Papers)
The long delay of the MS. of Col o Byrd which you were so kind as to send me , needs apology. on the 26 th of June I wrote to mr Benjamin Harrison of Berkley from whom the other had been borrowed, to ask permission to send it to the Philosophical society with a view to it’s publication. the following is an extract from his answer of July 11.
5Thomas Jefferson to Peter S. Du Ponceau, 7 November 1817 (Jefferson Papers)
A part of the information of which the expedition of Lewis and Clarke was the object has been communicated to the world by the publication of their journal; but much & valuable matter remains yet uncommunicated. the correction of the longitudes of their map is essential to it’s value; to which purpose their observations of the Lunar distances are to be calculated & applied. the new subjects...
6Thomas Jefferson to Peter S. Du Ponceau, 30 December 1817 (Jefferson Papers)
An absence of 6. weeks has occasioned your letters of the 5 th & 11 th inst to lie thus long unacknoleged. after I had sent off the two other Westover MSS. I recieved a 3 d of the same journal. on perusing it, I am not sensible, by memory, of any thing not contained in the former, except 8. pages of a preliminary account of the abridgment of our limits by successive charters to other colonies....

Your favors of the 5 th & 6 th are recieved, and I am sorry it is not in my power to interest any of the Indian agents for you & particularly those of the 4. Southern tribes . these are all new men to me. mr Meigs Agent with the Cherokees would be the most likely to be useful to you. I recieved last night a letter from mr Harrison , who had been so kind as to give me the pocket MS. of Westover...
10Thomas Jefferson to Peter S. Du Ponceau, 7 November 1817 (Jefferson Papers)
Th: Jefferson presents his compliments to M r Duponceau , & his thanks for his pamphlet on Phonology. he supposes, with him, that all sud d en reformation of our orthography is as desperate as it would be inconvenient. he presumes the slow process of amendment will continue, which has been going on for ages; that this may in time reduce the power of the letters to greater uniformity, as has...
11Thomas Jefferson to Peter S. Du Ponceau, 19 February 1818 (Jefferson Papers)
your favor of Jan. 24. was duly recieved, and I now inclose you the supplements for the three hiatuses in your MS. all your references were found satisfactorily except that of March 9 th to the words ‘bush, which is a beautiful evergreen, & may be cut into any shape.’ I found no such words under that date in the folio MS. and therefore had the whole of that day copied. it is the only instance...
