EPIZOOTIC AMONGST EOWLS IN THE DEPARTMENT 
OP GIRONDE. 
By M. Dupont, Bordeaux. 
For about fifteen years the fowls in the department of 
Gironde have been visited by an affection which carries off 
yearly a great number of them. This malady from its 
commencement assumed the character of an epizootic which 
has not yet been described. In 18.54-5, it destroyed 
nearly all the fowls in several villages hygienically the most 
favorably situated in the department, and has since visited 
all the districts, and carried off the fowls of many farm¬ 
yards. It differs essentially both in symptoms and lesions from 
the epizootic which prevailed in 1851 in the north of France, 
and wdiich w^as the subject of a communication to the Academy 
of Medicine, by the then Director of the Veterinary School 
of Alfort, M. Renault. 
Left to itself, this malady is very destructive. Its dura¬ 
tion is from five to eight days. It does not attack at once 
all the fowls of a farmyard, but at short intervals, one by 
one, and selects generally the best fowls. It is very contagious. 
Isolation and disinfection at thebeginningoften stop its course. 
The continuance on the premises of a diseased or a dead fowl 
only for one day suffices to propagate the malady. It makes 
its appearance almost periodically in the spring in the envi¬ 
rons of Bordeaux, in places wdiere it has previously pre¬ 
vailed. 
Symptoms ,—It attack is sudden, a little dulness is perceived, 
the locomotion of the bird is slow^er, but this is hardly per¬ 
ceptible the first day ; it soon increases, however, to a real 
difficulty. Thus, at the commencement the bird can still run 
and fly, less fast, it is true, than the healthy ones, but the next 
day it is unable to do either; the habits of the birds become 
greatly modified,they isolate themselvesfrom the others,do not 
seek for food, do not roost, the sight is altered, the voice hoarse 
and short, the respiration becomes slightly croupy; if we now 
examine the inside of the beak we are struck with the w^an 
appearance of the tongue; if we lift up this organ, by slightly 
drawing it out, w e perceive on the sides of the dorsum, at its 
base, some small spots of a greyish colour shaded with 
black; examined by a lens, these appear like a granular 
eruption, or a simple hypertrophy of the papillary follicles. 
The paleness of the tongue is a strong contrast with the
