flowed from the nostrils. The animal died on the 25th 
day of his illness, after having passed an immense quantity of 
pus through the nose. After death, the mucous membrane of 
the larynx was found much thickened, the sinuses of the glottis 
filled with pus, and abscesses of various dimensions surrounded 
the larynx. 
It appears that in these chronic cases of laryngitis the mucous 
membrane was always thickened. In one case Rinquet ob- 
served three greyish ulcers, with jagged edges, and, here and 
there, deposits of tuberculous matter. Rinquet says, these 
lesions constituted what might be designated e( Laryngeal 
phthisis . 55 
The causes of this disease have not been studied. The 
roaring occurred so suddenly that it was often thought to be 
due to impaction of foreign substances in the oesophagus. 
The treatment adopted consisted in fumigating the nostrils, 
bleeding and blisters. Indeed, much the same as in the 
horse. — Journ. des Vet. du Midi, June, 1855. 
Youatt, in his work on cattle, says a very few words on 
laryngitis, at page 395. He says it is attended with loud and 
laborious breathing. Rychner, in his Beyatrik, gives a long 
history of the affection. 
Reflections on a Tooth extracted from the Vi- 
cinity of the Ear. — M. Lafosse,* professor of clinical me- 
dicine in the veterinary school of Toulouse, had under his 
treatment a four-year-old mare, that, two months before 
admission into the infirmary, was affected with a phlegmonous 
tumour in the vicinity of the left ear. This was opened ; the 
wound that resulted rapidly contracted, but a fistula remained. 
On the 8th of February, 1855, when Lafosse first saw the case, 
he found a painful tumour, with a granulating wound just be- 
hind the scutiform cartilage, and near the upper part of the 
parotid gland. The mare was restless, and the parts could only 
be examined in a complete manner the day after, when she 
was cast. By probing, he ascertained that at the bottom of 
the fistulous tract was some hard substance, which he sup- 
posed to be the scutiform cartilage in an ossified state, or a 
portion of the temporal bone exfoliating. A severe operation 
was performed, and the solid object, with some difficulty, 
extracted. It was double, deeply seated, and firmly adherent 
to surrounding textures. Slight hemorrhage occurred, from 
division of the anterior auricular, which was easily stopped ; 
the wound was dressed, and the animal soon recovered, having 
shown only a few symptoms of sore throat after the operation.
