CANCEROUS TUMOUR IN A DOG. 
451 
the setter and pointer, the property of H. Lyne, Esq., Keyn- 
sham. The animal was sent to my infirmary last week, the 
servant stating that the dog had been ill about two months, 
and was supposed to have worms, for which some medicine 
had been given him. The symptoms which presented them- 
selves were an extremely emaciated condition, the respiration 
occasionally excited, but not laboured, at other times tranquil; 
pulse quick and weak; the abdomen tucked up, tense and 
hard to the feel; appetite pretty good. On more carefully 
manipulating the abdomen, I could feel that I was enabled 
to move something of large size backwards and forwards, and 
which appeared to occupy nearly the whole of that cavity. 
The owner of the dog called in the course of a few days, 
when I informed him that it was my opinion a tumour ex¬ 
isted in the cavity of the abdomen, and that nothing I could 
do would be likely to afford any relief to the animal, as I 
feared the consequences of an operation, from its size and 
situation, and therefore advised that the dog should be at 
once destroyed, with which the owner concurred. 
. Post-mortem appearances .—On cutting open the abdomen, I 
observed a large tumour, weighing 3^ lbs., occupying the 
greatest portion of that cavity. It was lying somewhat ob¬ 
liquely across the spine, resting upon the stomach, covered 
by the omentum, and attached by its peduncle around the 
aorta, near to the opening in the diaphragm. The stomach 
and intestines were healthy. The liver was natural in colour, 
but contained several tumours about the size of marbles; 
one, however, was as large as a pigeon's egg. The lungs were 
pale, and contained many of these tumours, varying in size 
from a pin’s head to a marble. The tumours in the liver 
and lungs appeared to be made up of the same peculiar 
structure as the one I have forwarded to you. 
If you think the case of any interest, I should feel greatly 
obliged by your opinion as to the nature of the disease, 
through the medium of your journal. 
[The tumour forwarded by Mr. Dring consisted of a mass 
of cancerous matter, involving the mesenteric glands. Soften¬ 
ing had taken place here and there, and collections of pus 
were likewise met with in various-sized cysts in the interior 
of the tumour. The appearances, on the whole, however, 
differed but little from ordinary - cancerous deposits as met 
with in the dog.]
