cal work that has made the family name a household word in the 
science of all countries. 
On the death of his father in 1841 he succeeded to the author- 
ship and editorship of the “Prodromus systematis naturalis regni 
vegetabilis,” the great work in which the elder De Candolle hoped 
to concisely describe all the known plants of the world, his name 
appearing on the title page of the eighth volume, issued in 1841, 
and continuing up to the issue of the seventeenth, in 1873, when 
the work was abandoned, its place being taken by the “ Monogra- 
phiz Phanerogamorum,” a series of seven thick volumes of which 
has been printed. Among his earliest works is the noteworthy 
“Monographie des Campanulées,” a quarto of 384 pages and 20 
plates, issued in 1830, M. De Candolle being then but 24 years 
old. In later years he devoted himself to the study of geographi- 
cal distribution, and in 1855 his‘*Geographie botanique raisonée”’ 
appeared in two volumes of 1366 pages. He was the moving 
spirit in the International Botanical Congress, held at Paris in 
1867, when the modern laws of botanical nomenclature were 
framed ; and if these had been carried out in the way they were 
intended, there would have been no necessity for the recent move- 
ments to secure a stable system of plant names. More recently 
he has critically investigated the origin and history of cultivated 
plants, and published numerous papers on this subject, bringing 
together in his “ Origin of Cultivated Plants,” in 1882, about all 
the reliable information that was then extant. 
In view of the loss which botanical science has experienced by 
his death, we recommend the adoption of the following resolution : 
Resolved, That by the death of Alphonse De Candolle, after a 
long life rich in contributions to the knowledge of mankind, 
botanical science has suffered an irreparable loss; and 
Resolved, That the sympathy of the Torrey Boranicat Cxvs is 
extended to the family of the deceased savant.
