ROYAL AND CENTRAL SOCIETY OF AGRICULTURE. 
PUBLIC SITTING, APRIL 10, 1836. 
By M. Huzard, Sen. 
Report of the Works , Memoirs and Cases relating to Practical 
Veterinary Medicine , presented at the Concours . 
The Society has received fifteen printed works, and thirty-four 
memoirs or cases, addressed to them by twenty-nine veterinary 
surgeons, civil and military, natives and foreigners, and also by 
medical men, and the proprietors of cattle. 
The committee cannot dissemble that several of these works 
and memoirs wander, more or less, from the special object of the 
society; nevertheless, they prove the zeal and industry of the con- 
tributors, and'theirdesire to be useful, and tomerityourapprobation. 
It would be impossible in the space allotted to this meeting 
to analyse all these productions, and the committee will confine 
itself to the enumeration of i,hose practical works that appear to 
be most valuable ; and they propose that the honours and prizes 
should be awarded in the following order : — 
1. M. Didry, veterinary surgeon to the arrondissement of 
Montmedy, in the department of the Meuse, who obtained the 
large silver medal at the concours of 1830, and the gold medal 
in that of 1831, has addressed to you this year a memoir on 
u staggers in the horse.” This disease prevailed as an epizootic 
in 1831 and 1832 in the arrondissement, and was frequently fatal. 
M. Didry had occasion to examine thirty-eight horses after 
death. He attributes the malady to the bad forage of 1830, the 
constant dampness of the air, local inundations, and over-work. 
Colts and horses that did not work hard seemed to be exempted 
from its attack. 
M. Sarget, V.S. in the department of the Correza, and who 
obtained honourable mention in 1828, has contributed some 
observations on the employment of the chloride of sodium in the 
typhoid fever of cattle, both internally and externally. His 
cases, which shew that the exhibition of it is attended with con- 
siderable advantage, deserve to be repeated, and put thoroughly 
to the test.
