small marble books ; the one brown book ; and eleven of the thirteen red 

 books. With these l)elong all the loose papers, as above said. 



2. The Jeirersou deposit, consisting of three bound volumes. Two of 

 these are small maible books, matching the other two deposited by 

 Biddle. Each is by both Lewis and Clark, and each consists of miscel- 

 laneous field notes, mainly on zoology and botany. They now form 

 Codices Q, R. Tiie third volume is one of the red books. It is a Clark, 

 and contains miscellaneous notes, chiefly on natural history. It is now 

 Codex P. These three were deposited by Mr. Jefferson in November, 

 1817, as appears by memorandum in eacli of ihem, in Riddle's hand. 



3. Unknown deposit : One of the thirteen red books, without record of 

 source whence obtained. This is a Lewis, and consists of certain astro- 

 iiomical observations and geographical notes. It is now Codex O. 



III. The Books and Papers as Arranged. 



I have gone very carefully through these precious manuscripts, and 

 arranged them in what appears to be their natural sequence or logical 

 order. All the red books, making the bulk of the collection, fall easily 

 together, preceded by two of the small marble books and by the brown 

 book, followed by the other two small marble books, and the set of bound 

 volumes is interspersed with the twelve parcels of unbound manuscripts 

 which I have made up from the loose sheets, securely fastened in stift 

 paper covers, and for the most part interleaved with onion-skin Avriting 

 paper. I have also paginated the whole of the manuscripts, which can 

 now be cited by codex and page throughout, as if by volume and page of 

 a published work. There is in all upward of 2,000 pages. Description 

 in detail of the now thirty (30) codices here follows :
