sciences, and it is only in the moment of imbecility or mental in- 
firmity that an attempt has been made to separate the one from the 
other. The only legitimate distinction between them is, that the 
patient of the one is far superior to that of the other in the duties 
of the present scene and his future destination. It is not impossible 
that, at some future period, it will again be as it was in the early 
times of medical science, the medical attendant of the human being 
will be consulted with regard to the ailments of the brute. 
A case which occurred in our hospital may, perhaps, have con- 
tributed to suggest to us the line of thought which we have now 
pursued. About the same time that M. Bonnet removed a tu- 
mour, weighing fourteen pounds, from one of his patients, we were 
called upon to extirpate one of fifty pounds that had grown on the 
neck of a mule. 
The form and disposition of this enlargement on the neck of the 
mule was very remarkable. It was composed of three parts of 
unequal volume. The first, and the most voluminous, hung down 
on the right side, and reached below the inferior border of that divi- 
sion of the upper part of the neck : it was a foot and a half in length, 
and measured two feet at its base. The second tumour was smaller. 
It was nine inches in height, and only seventeen inches in circum- 
ference : it hung from the left side of the neck, and reached to the 
border of the lower jaw. The third was the smallest of the whole : 
it grew between the other two, and was not above six inches in 
height or circumference. 
It would be imagined that such a tumour would very much 
annoy the animal, and would prevent it from executing its ordi- 
nary work. His pace was slow, and he did exhibit some degree 
of embarrassment. He carried his head unusually low. The 
blood in the jugular vein, impeded in its course, had distended the 
parietes of the vessel, and produced several varicose portions, and 
its stagnation in the vein produced a kind of permanent cerebral 
congestion. 
A tumour on the same place had been removed by us eight years 
previously, and when it was far less voluminous than the present : 
it had, however, been reproduced with very great rapidity. On 
carefully examining it, the existence of various lobular masses was 
ascertained, of different sizes, rather dense, separated by con- 
densed laminae of cellular tissue, and the whole provided with a 
strong pedicle. The integument was sound, and the hair had the 
same appearance as on other parts of the body. 
The proprietor of the animal having been made aware of the 
danger of extirpating so great a mass, we consented to operate on 
the animal, for he had now become incapable of work. We 
determined to operate by tying the jugular vein as near to the head
