OF THE CEREBELLUM IN A HORSE. 
239 
The cause of all the symptoms which I have described and of 
the death of the animal was found in the cerebellum. Towards 
the median line of that body, in the thick part of its substance, 
between the ventricle and its superior surface, and extending 
through the whole length of the organ, was a winding cavity of 
many compartments, almost isolated, filled with a substance 
of a white or slightly yellow colour, and of the consistence of pus. 
The walls were somewhat less firm than the remaining portion of 
the cerebellum, but their colour was not altered. I could not find 
any trace of hemorrhage either in this softened substance or 
in the encephalic mass generally. The vessels were not even 
injected. 
This case is remarkable in the triple relation of the seat of the 
rarnollissement, its extent, and the almost complete discolouration 
of the softened cerebral mass. 
If this rarnollissement had been accompanied or caused by any 
hemorrhage, that hemorrhage could not have been very great, for 
the duration of the illness was not sufficiently long to permit any 
great quantity of blood to be absorbed. That which appeared to 
me to prove that the hemorrhage could not have been very con¬ 
siderable even if it existed at all, was, that the dissolved substance 
exactly filled the cavity in which it was found. 
I should also remark, that during life this horse had not exhi¬ 
bited that excessive sensibility which I remarked in another patient 
that died of inflammation of the cerebellum. 
Finally, there was no excitation of the genital organs, or erection 
of the penis. After all, it is very probable that the softening of the 
nervous centres might have taken place without any inflammation 
preceding or accompanying it, and without hemorrhage. On 
this ground we can explain the serious nature of the lesion, and 
the non-effect of every medicine that was resorted to.

We are aware of but one other recorded case of rarnollissement 
of the cerebellum, and that we extract from the Recueil de 
Med. Vet. for 1825. It is related by M. Ollivier, of St. Maximin. 
Being requested to visit a young horse that had suddenly 
dropped when at work, I found him dead. The owner gave me 
the follow'ing account of him. That he had begun to work him in 
a cart at three years old ; that he was at first full of spirits, threw 
himself honestly into the collar, and was in excellent condition. 
After some months, however, he began to get too fat, and some¬ 
what lazy. One day his appetite seemed to fail, nevertheless he 
was put to his usual work. lie hung his head, crept slowly and 
listlessly along, and even a severe application of the whip would 
scarcely make him quicken his pace. (.)n tlie following day he
