the astronomical and geographical papers, those relating to zoological, botanical, and mineral subjects, with the Indian vocabularies, and statistical tables relative to the Indians. Of the astronomical and geographical papers, if the committee will be so good as to give me a statement, I will, as soon as a Secretary at War is appointed, propose to him to have made, at the public expense, the requisite calculations, to have the map corrected in its longitudes and latitudes, engraved and published on a proper scale; and I will ask from General Clarke the one he offers, with his corrections. With respect to the zoological and mineralogical papers and subjects, it would perhaps be agreeable to the Philosophical Society, to have a digest of them made, and published in their transactions or otherwise. And if it should be within the views of the historical committee to have the Indian vocabularies digested and published, I would add to them the remains of my collection. I had through the course of my life availed myself of every opportunity of procuring vocabularies of the languages of every tribe which either myself or my friends could have access to. They amounted to about forty, more or less perfect. But in their passage from Washington to this place, the trunk in which they were was stolen and plundered, and some fragments only of the vocabularies were recovered. Still, however, they were such as would be worth incorporation with a larger work, and shall be at the service of the historical committee, if they can make any use of them. Permit me to request the return of General Clarke's letter, and to add assurances of my respect and esteem. P. S. With the volumes of MS. journal, Mrs. Barton delivered one by mistake I suppose, which seems to have been the journal of some botanist. I presume it was the property of Dr. Barton, and therefore forward it to you to be returned to Mrs. Barton. TO MR. CORREA. POPLAR FOREST, November 25, 1817.
