832 SYNOPSIS OF CONTINENTAL VETERINARY JOURNALS. 
mass, fairly consistent, and of a bad odour. On scraping 
the ulcerated surface with the finger we may detach material, 
of about the size of a small pea or bean, which yields 
between the fingers, and becomes a sort of confused mass by 
loss of all traces of organisation. The living tissues thus 
exposed are of a red colour, bleed readily, and here and there 
may be seen greyish points, indications of necrotic invasion. 
The centre of the mortified mass is strongly adherent to the 
tissues of the cheek, and in the cleansing of the wound, 
which was immediately performed, some difficulty was ex¬ 
perienced in separating the deeper parts. Everywhere else 
the mouth is healing. 
Treatment .—Cleanse the two ulcerations twice a day, 
removing as much of the necrosed material as possible with¬ 
out causing bleeding. Dress twice daily with solution of 
perchloride of iron. Nourish well, giving a little coffee daily, 
and exercise moderately in the fresh air. 
February 19th.—The case has become aggravated. On 
the outer surface of the two cheeks and on a level with the 
ulcerations, are two hard tumours, and painful on pressure. 
The ulcerations much larger than on the 15th. They have 
become black, evidently in consequence of the chloride of 
iron used as a lotion, and showing no sign of cicatrization. 
The calf drinks well, but has fallen away in flesh con¬ 
siderably. Pulse 82, and rather small; conjunctivse some¬ 
what injected ; considerable debility ; prognosis unfavorable. 
The owner urged more energetic measures. Consequently 
six grammes of chloride of potash was administered daily 
in addition to the measures previously adopted. This was 
continued for five days, when there was evidently no longer 
any room for hope of a cure. The animal lay stretched out 
on its side, the mouth was filled with frothy saliva impreg¬ 
nated with greyish matter ; respirations much accelerated ; 
pulse imperceptible ; conjunctive of a deep red colour. 
Severe diarrhoea had been present for two days and the 
posterior parts of the body were covered with filth. The 
calf was destroyed and autopsy proceeded with forthwith. 
It disclosed a sanguineous suffusion of the last part of 
the colon, pneumonia of the inferior two thirds of each 
lung; but the principal and essential lesions were found in 
the head. The trachea and larynx contained a little frothy 
mucus. The vocal cords were slightly cedematous and of a 
dark red colour. Mucous lining of the pharynx thickened, 
of a violet tint, but nowhere showing the slightest trace 
of gangrene. By means of a lens magnifying about four or 
five times, might be easily seen here and there some points
