204 The Management and Diseases of the Dog. 
{argement was movable and soft. As it was too extensive 
to remove without blemishing the dog considerably, and as 
it did not cause any pain or inconvenience, I deemed it 
advisable to let it alone. In a week or ten days after- 
wards, my farrier-major brought me a portion of a 
dog’s lung, which he said was obtained from this setter, 
it having suddenly died the day before. The surface 
of the lung was covered with round, soft, globular 
masses, as black as ink, varying in size from a millet-seed 
to alarge pea. He had opened the dog, and stated that 
he found the swelling on the leg full of black matter. The 
liver, heart, other portions of the lungs, and beneath the 
skin over the body, were all in the same condition as the 
portion of lung which he brought to me. Examination of 
the latter proved that the deposits were of a melanotic 
mature, and no doubt had been the cause of death.” 
I have at the present time, 1888, a melanotic subject 
under treatment, a young black retriever. The tumour, 
which is mulberry-like, has continually for some time past 
broken out, the discharge being like thick tarry ink. The 
deposit is situated on the withers between the shoulders. 
I purpose removing it by excision.* 
CANCER. 
The same varieties of cancer exist in the dog as occur 
in the human being. Scirrhous and encephaloid are the 
most prominent forms met with in canine practice. I have 
met, however, with cases of melanoid, osteoid, and gum cancer. 
Cancer of the mammary gland has already been men- 
tioned in chapter xi. though the majority of such so-called 
cases are spurious. I have, since writing that section, had 
several decided illustrations of true cancer growth in con- 
nection with the mamma. Amongst the cases I have 
recorded, there will be found an interesting one in the
