REMARKS ON ENTOZOA.

then excreted on the surface of the bowels ; but from the fact of 
entozoa occurring in the substance of nerves, in the testicle, 
in muscles, there is almost conclusive evidence that the 
germs have been deposited by means of the circulatory 
current. 
Much relating to this interesting subject yet remains wholly 
within the region of conjecture ; and it is only by the patient 
observation of numerous experiments that we may hope to 
fathom it correctly. Still we think such observations are 
not so common as they might be. In the pursuits of the 
veterinary profession, what extensive opportunities of inves- 
tigating such subjects might be found, if its members would 
devote themselves more zealously to the study of compara- 
tive anatomy ! In fact, this branch of study should be 
taught at all veterinary schools ; and this is even more neces- 
sary to the veterinarian who professes to be acquainted with 
the diseases of all the lower animals, than to the medical 
man, who has only the human species as his patients. Many 
say that the veterinary surgeon, during his short course of 
study, has at present enough to acquire without this addi- 
tion of another branch. This is certainly too true ; and the 
only remedy is to lengthen the period of attendance at 
College. This must, in the end, be done. Two courses of 
even six months’ duration, are not sufficient to enable the 
student to acquire, creditably, all the subjects he undertakes ; 
and until the colleges exact a better preliminary education, 
and a longer period of professional study, the veterinary 
profession cannot hold the position to which it is justly 
entitled. 
DEATH CAUSED BY PHYSICKING. 
To the Editor of 6 The Veterinarian 
Sir, — On the 4th of the present month I was requested 
by E — E — , Esq. to go to his farm, about a mile from this 
town, to examine the dead carcase of a bay horse, that died 
early that morning, and of which he was anxious to ascertain 
the cause. I shall feel obliged if you will give me your 
opinion whether or not the ball administered was the pro- 
bable cause of the horse’s death. 
Yours very truly, 
G. M. Marshall.
