HYDATID IN THE BRAIN OF A HORSE,

Secondly^ it is universally believed that the habit arises from 
indigestion. Thirdly^ that if continued, structural alteration 
of parts will take place; diudi, fourthly, it is shown that such 
horses are more liable to colic than others. It does not, 
therefore, follow that because an animal looks well, feeds well, 
and does his work well, that his inward parts are not diseased. 
If we turn to the human subject, we find numberless instances 
of men whom we know to have diseased structures; still 
they do their ordinary business, but certainly not with the 
same degree of comfort to themselves as if they were free from 
disease. It does not prove, then, that diseased structure does 
not exist because we are not in a position to demonstrate it. 
A crib-biting horse is, to all intents and purposes, an unsound 
one. He would be denominated usefully sound.

A CASE OF HYDATID IN THE LATERAL VEN¬ 
TRICLE OF THE BRAIN OF A HORSE, OCCUR¬ 
RING IN THE PRACTICE OF MR. WOODGER, 
M.R.C.V.S., PADDINGTON. 
Communicated by Professor Varnell. 
The particulars of this unusual and very interesting case 
were furnished me by Mr. A. Woodger, M.R.C.V.S., Pad¬ 
dington. The novelty of the occurrence induced me to lay 
the case before the members of “The Veterinary Medical 
Association,” together with the brain, which Mr. Woodger 
had taken from the horse the subject of these remarks. 
It appears that the animal was the property of the “London 
General Omnibus Company,” in whose service he was used 
as long as it was found practicable to do on account of his 
peculiar comportment when at work. Mr. Woodger in¬ 
formed me that originally the attention of one of the super¬ 
intendents of the company was directed to the animal on 
* account of his not performing his work as he ought to do. 
In the stable, however, nothing whatever could be detected 
as being wrong with him; he ate and drank well, and his 
secretions and excretions were natural. When at work his 
place was on the “ off side,” but instead of going forward as 
he should do he continually bore away from the pole, and 
sometimes to such an extent that the driver had very great 
difficulty in avoiding coming in contact with other vehicles. 
As an experiment, he was placed on the near side, when it
