106 The Management and Diseases of the Dog. 
CANCEROUS DEPOSIT IN THE LIVER AND 
SPLEEN IN THE. DOG, 
Veterinarian, Jan., 1870. 
“We are indebted to Messrs. Gowing & Son for the par- 
ticulars of two remarkable cases of cancer affecting the in- 
ternal organs of the dog. In each case the animal was aged, 
and in a hopeless condition when first seen by Messrs Gow- 
ing, consequently no treatment was attempted. 
“ Post-mortem examination was made soon after death, 
and the appearances satisfactorily explained the condition 
of the dogs during life. 
“Tn the first case, which was examined in the beginning 
of October, there was a large nodulated tumour, of a pale 
greyish-yellow colour at the root of the mesentery. Num- 
erous deposits of a similar character were found all over 
the liver, both covering the surface and extending to the 
interior of the gland. 
“ Under the microscope the deposit was found to consist 
of cells of various forms, caudate, spindle and fibre-cells, 
with many others containing nuclei, and evidently multi- 
plying by the endogenous process. 
“A considerable quantity of fine fibrous stroma gave to 
the deposit a density and hardness characteristic of scir- 
rhous growths. There was scarcely a trace of the milky 
juice which is an invariable constituent of encephaloid 
tumour. 
“The second animal presented appearances in some re- 
spects more marked than those which have just been de- 
scribed. The subject of the disease was a Maltese dog, 
aged fourteen years, which was seen by Messrs. Gowing 
only a few hours before its death. 
“On post-mortem examination the liver was found to be 
covered with yellowish spots, and a tumour of similar char- 
acter was detected in the spleen. 
“ Microscopic examination of the morbid deposit resulted
