4G8 OSSEOUS TUMOURS COMPLICATED WITH GLANDERS. 
and the membrane of the nose thickly set on both sides with 
chancres covered by black scabs. There was considerable pros- 
tration of strength, and .discharge of black feeces of a most 
offensive smell. 
I remarked on different bones a great number of tumours, 
hard, deep, fixed, large at the base, and with a rounded summit, 
and not in the slightest degree painful when pressed upon. These 
tumours appeared all at once, or, at most, in the space of two 
cr three days; the horse labouring, at the time, under the highest 
degree of fever, and being covered with a profuse perspiration. 
They gradually increased in size for three weeks; they then 
seemed to be stationary, and the other symptoms, of which an 
account has been given, appeared, and made rapid progress. 
After due consideration of all the circumstances, I advised 
that the horse should be destroyed, to which the owner readily 
consented. 
The sublingual glands were discoloured, and were four times 
their natural size. The pituitary membrane on both sides was 
almost destroyed by large chancres, covered by black scabs, as 
already described . Other portions of the membrane were blanched 
and thickened. The turbinated bones contained a purulent matter, 
similar to that which had been discharged from the nostril. The 
septum of the nose was also thickened. The sphenoidal, frontal, 
and maxillary sinuses contained a little white pus. There was 
nothing peculiar in the spinal cavity. 
The lungs, of a violet colour, contained a great many tubercles, 
some of which were miliary, and others larger than a nut. The 
posterior portion of the right lung contained a vomica, into which 
two fingers might be introduced : there was adhesion between 
the pulmonary and intercostal and diaphragmatic pleurae at the 
situation of this vomica. 
The other thoracic viscera, and all those of the abdomen, pre- 
sented a healthy appearance. 
I conclude with, an account of the osseous tumours to which I 
have alluded. The largest was situated on the transverse apo- 
physis of the third cervical vertebra on the right side ; and the 
next in size on the superior extremity of the apophysis of the 
right olecranon. There were others on ten of the ribs, six on 
the right side, and four on the left. Six of these ribs presented 
only one tumour, but the other four had two or three tumours on 
each of them. 
These tumours, all of which seemed to be part of the bones 
on which they were found, were true cysts with bony walls, and 
whose centre contained a cavity filled with a thick grumous 
yellow fluid.
