Rosier, Francois (1734-1793) 
Cours complet d’agriculture theorique, pratique, econo- 
mique, et de medecine rurale et vet'erinaire. Ou Dictionnaire 
universal d’agriculture ... redige par Rqzier ... Precede 
d’vin discours sur 1’exposition ... de 1'economic rurale ... 
par M. A. Thouin. Paris, 1781-1805. 12 v. (Dept. Agr.j 
Lib. Cong.j Brit. Mus.) 
The Brit. Mus. Cat., from which our title and 
collation are taken, gives the dates as 1801-05, 
but the dates of volmes of the Dept. Agr. copy, 
v.1-10, run from 1785 to 1800. Volumes 1, 2, 3, 
6, are dated 1785; v.4, 7, 1786; v.5, 1787; v.8, 
1789; V.9, 1796; v.lO, 1800. The Lib. Cong, set 
likewise has v.1-10, 1785-1800. 
Pritzel, both eds., and Brunet, 4:106, both 
give 1781 as date when publication began. The 
Dept. Agr. copy of v.l, with date 1785, contains 
the "avis de I'editeur," p.vi, which apologizes 
for delay in the appearance of the first volume, 
which had been advertised for the end of 1780. 
On the opposite page is the "approbation," which 
is dated May 16, 1781. Dugour, in his sketch of 
the life and works of Rozier, in v.lO, p.i-xvj, 
states (p.x) that "Le premier volume du Cours 
d’agriculture parut en 1783." Altho we do not 
find any evidence of the issue of this work in 
parts, it is possible that some portion of v.l 
may have come out prior to the title date 1785. 
Pritzel states that the last 3 v., prepared 
after the death of Rozier in 1793, were edited 
by Andre Thouin and Antoine Augustin Parmentier. 
As a matter of fact, v.lO, 1300, was edited by 
Chaptal, Dussieux, Lasteyrie, Cadet-de-Vaux, Par¬ 
mentier, Gilbert, Rougier-Labergerie and Chambon, 
while the names of Thouin and Parmentier appear 
at the head of the list of editors of v.ll and 
V.12, both issued in 1805, according to Allg. Lit. 
Ztg., May 23, 1807, no. 123, col. 977-980; and Beck¬ 
mann, Phys.-Oekon. Bib., 23:259-266 (1805). The 
long intervals between the last 4 volumes may ac¬ 
count for some other incomplete copies, such as 
that of the Roy. Agr. Soc. in 10 v. (1797-1800), 
and one of 8 v. in the N. Y. Society Library.
