Vetermary Journal for February, 1880, the subject being 

 the deerhound bitch " Teilda." On making a section of 

 the growth I removed, which weighed, over half-a-pound, 

 the scirrhous type of cancer, in both stages, hard and 

 soft, -was found to be well marked — the former in the 

 centre, the latter towards its circumference. The external 

 appearance of the cancerous gland, before operation, was 

 glazed, tense, and of a varied livid hue. In several places 

 it was puckered, and the nipple retracted. There were 

 three fistulous woundsj^from which a thin offensive dis- 

 charge issued. In 1886 I operated on two very typical 

 cases from Hastings and Battle, but, in both instances, 

 secondary growths elsewhere took place. 



Cancer frequently invades the canine liver. A case 

 (encephaloid) involving the liver and spleen of a retriever 

 dog, nine years old, is recorded by the author in the 

 Veterinary Journal for June, 1880. Also another very 

 remarkable case in the Live Stock Journal for July 13th, 

 1883 ; the subject being a pointer, nine years old, in 

 which death occurred from embolism of the posterior 

 vena cava. A post-mortem examination revealed, 

 amongst other complications, large deposits of medullary 

 cancer in the liver. In making this autopsy, I had the 

 misfortune to become inoculated on the forefinger of 

 the right hand, and had a narrow escape from death. 



Two cases of melanoid cancer will be found under the 

 heading of " Melanosis." 



Osteoid cancer (osteo sarcoma) is most frequently met 

 with in the bones of the fore-arm. I have had two well- 

 marked cases in my hospital practice, the one subject 

 being a mastiff dog, bred by myself, the other a St. Ber- 

 nard bitch. In both instances the radius, ulna, and carpal 

 bones were involved, an enormous mass of honeycomb- 

 like osseous deposit being especially thrown out on the 

 radius. These cases, with full particulars, are recorded in 

 the Veterinary Journal, Amputation might successfully
