MISCELLANEA.

tremely black, and of a disagreeable smell. I collected some in 
a glass, to enable me to examine its physical characters. While I 
proceeded in the bleeding, and which yielded only a feeble jet of 
blood, although the vein was largely opened, the animal threw 
himself once more on the ground, and died in violent convulsions 
in the space of some minutes. 
Examination of the blood . — The coagulation had taken place in 
ten minutes. The clot preserved its colour of blood — a deep brown. 
The cohesion of the parts constituting the clot was very feeble ; 
it was reduced to a species of deliquium, so that I seized it with 
my hand, in order to examine its physical character. 
The post-mortem examination . — Two hours after the death of 
the animal, the swelling began to commence : the pectoral organs 
did not present any thing remarkable, except the deep colour and 
the little consistence of the clots enclosed in the ventricles of the 
heart — the red tinge of the internal membrane of the pulmonary 
veins, and of the serous membrane which lines the auricles and 
ventricles of the heart. 
At the opening of the abdomen I found about four pints of blood 
effused in the diaphragmatic region of that cavity. I then care- 
fully examined the haemorrhage that had taken place. I saw that 
the spleen, double its natural size, presenting at its surface there 
sanguineous tumours, placed immediately under the splenic cap- 
sule. One of these tumours, situated at the base of the spleen 
near the grand scissures, was opening and had run, and given 
space to the blood which I had met with. It formed a wound 
five centimetres in length, the bottom of which presented a deep 
lobulated matter, and might be compared with the matter of melanosis 
in its state of ramollissement. 
The second of these tumours, placed at fifteen centimetres from 
the first, contained an extreme red fluid serosity. 
The third, placed at the opposite face and near the point, had 
two lobes of the size of a common nut. 
As to the general alterations of the spleen, I have already said 
that its volume was of double the usual size. Its colour was not 
changed ; and its consistence, which I thought would do so, was 
not diminished, but, on the contrary, augmented, for she presented 
the characters which M. Andral assigned as induration of the spleen. 
The other abdominal organs presented nothing worthy of notice, 
except the mesenteric veins and the vena porta, the serous mem- 
brane of which presents that red tint of which I have spoken. On 
the whole, this is a very remarkable case of splenitis in the horse. 
But what is the cause of this affection 1 Of that I confess that I 
am ignorant. I think that it will be of considerable importance 
strictly to inquire into this.
