646 ROYAL AND CENTRAL SOCIETY OF AGRICULTURE. 
M. Blavette, V.S. at Bayeux, in the department of Calvados, 
has sent several cases of urethral lithotomy, complete dislocation 
of the hock, and of the cervical vertebrae ; the reduction of 
umbilical hernia in colts by the use of the suture entortillee # ; 
the successful treatment of palsy of the hind leg in a mare ; 
and fracture of the bones of the nose, and the extraction of a 
portion of them, from a colt. 
We propose tnat the society should make honourable mention 
of MM. Didry, Sarget, and Blavette. 
2. M. Canu,V.S. ofTorigny, in the department of La Manche, 
has sent us some observations on a malady produced by the use 
of clover hay as the food of colts. It is a species of gastric 
bilious fever, which attacks them during the winter, and espe- 
cially those that have been lately weaned. When taken at its 
commencement, it has yielded to bleeding and antiphlogistic 
treatment. 
Some remarks are added on a malady improperly called the 
marsh disease, because it attacks the colt bred on the upland 
ground, as well as those that are pastured upon the marsh. It 
approaches very nearly to anasarca, and its name indicates the 
principal cause of it. It attacks the colts in the winter, and 
often much perplexes the veterinary surgeon. It attacks almost 
every colt that is pastured on the marshes of Isigny during a wet 
season. On the uplands, and in dry years, it is occasioned by 
drinking unwholesome water, by suppressed perspiration, pecu- 
liarly frequent w 7 hen cold nights succeed to the burning days of 
autumn. It rarely attacks them after they are three years old ; 
it destroys great numbers of them, and the treatment, which is 
the same as for lymphatic diseases generally, is not always suc- 
cessful. 
M. Canu has also related a case of strangulated inguinal her- 
nia, in which the protruded intestine was much ecchymosed, 
covered with yellow and black spots. It was cured, contrary to 
all expectation, after the return of the intestine and the operation 
of castration. 
M. Roche Lubin, of St. Affrique, has sent a memoir, accom- 
panied by cases, on the most frequent diseases of ewes, during 
the period of their being milked in the neighbourhood of Roch- 
fort, preceded by an account of the agriculture of that district, 
and the manufacture of the Rochfort cheese. The diseases are 
all of an inflammatory character, and occasion very considerable
