]^ote. — This and R are the only codices of the whole series of which 

 Lewis and Clark are joint authors — though Lewis has a few entries in 

 Clark Codex C. 1 observe no marks by Biddle in the MS , and probably 

 he did not use this codex at all. It has some valuable descriptions, found 

 nowhere else, but on the whole is of much less importance to the natural- 

 ist than Codex P. It was long in Mr. Jefl'erson's hands, and deposited by 

 him in Nov., 1817.

Uordents. — (1) Letter to President Jefferson, dated St. Louis, Sept. 23, 

 1806, announcing the return of the Expedition. This is the rough origi- 

 nal, full of interlineations and erasures, from which a fair copy was 

 doubtless made and mailed to the President, Lewis retaining the present 

 MS. It is of great historic interest as a curiosity, but of no special value 

 otherwise. It is complete, with official signature and address ; it makes 

 5^ folios, or 11 pages, the second letter being on the same sheds as the
