GANGRENOUS CORYZA IN THE OX. 
By M. Lubin. 
GANGRENOUS coryza is one of the most fatal diseases that in 
the whole of my practice in the south of France I ever met with. 
It is considered as incurable in the districts in which I have seen 
it. It is curiously called the casque, doubtless because the head is 
the seat of the disease, and the animal seems to have this part, in 
a manner of speaking, borne down by the weight of a casque. Very 
seldom are the animals cured, and, out of the number which 1 have 
treated during the last twenty years of my practice, I have been 
able to save but very few. 
From the commencement of the disease the animal is dull, totters 
as he walks — the thirst is very great — the appetite diminished — the 
rumination seldom — the hair rough — the anterior part of the dorsal 
vertebra and the under part of the breast painful — the skin dry and 
adhering to the sides, and the pulse full and quick. To these 
symptoms, which are common in many diseases, are joined an abund- 
ant weeping, tumefaction of the eyelids and of the end of the nose, 
and dryness of the nasal membrane. This latter membrane and 
the conjunctiva are red — the pituitary membrane tumefied — the 
tongue very hot — the muzzle dry — the skin, and particularly about 
the ears and horns, absolutely burning — the respiration slightly 
laborious, and the flanks tucked up. 
About ten or twelve hours after the appearance of these symp- 
toms, which increase in intensity every hour, the appetite disap- 
pears, and the rumination entirely ceases. The animal falls into a 
complete state of stupor — he moves his head from side to side as if 
to get rid of something which annoys him ; but he seems to announce 
by the slowness and precaution with which he moves, an intense 
affection of the head. He is seized with shiverings, accompanied 
by convulsive movements of the muscles of the chest and face ; 
the pulse becomes hard and frequent ; and a thick viscous greenish 
matter runs from the nostrils. This running is not, as in other ani- 
mals affected by coryza, preceded by a more or less abundant 
running of serosity; it is thick from the first, and a very few hours 
are sufficient to render it so abundant as to oppose the free pas- 
sage of the air. There is slight pain in the aqueous humours — - 
the breathing more laborious — the excrements black and hard — the 
urine thick and rare and the animal indifferently standing or lying. 
Ere four-and-twenty hours are elapsed, all these symptoms are
