294 The Management and Diseases of the Dog. 



largement 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 a large 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 

 nature, 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 

 metjhowever, with casesof 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 mamms. Amongst the cases I have 

 recorded, there will be found an interesting one in the 



This I have since accomplished successfully.
