All letters were written to Adanson in French, unless indicated otherwise. The number of pages stated refer to the number of written pages; a leaf written on both sides is counted as two pages. The address, when on the back of a leaf, is not included in the page-count. All rectos and versos of the letters were scanned and are included in the PDFs. Letters are arranged alphabetically by the name of the originator. In many of these letters Adanson wrote (often interlineally) either a copy of his reply or a trial draft of same. In other instances the mss. consists only of a draft in his hand, identified below as “draft.”

The abstracts given below are selective and do not include all subjects treated nor all names of persons or places mentioned. None of the passages is to be considered a direct or free translation of the original letter. Spelling of dates cited are as in originals, as is that of all passages.
