MAMMARY ADENOMA IN THE BITCH WITH PULMONARY METASTASIS. 517 



right limb from the haunch downwards became greatly swollen, as did 

 the sheath and subcutaneous connective tissue under the abdomen. 



The horse was killed on the 17th January, the autopsy revealing 

 the above-described tumour, which weighed fifty pounds. There was 

 evidence of chronic peritonitis ; the abdomen contained several gallons 

 of sanguineous fluid ; all the abdominal and thoracic organs were 

 healthy. 



Microscopical examination showed the growth to be a round-celled 

 sarcoma. 



The testicle was soft and pulpy ; all the testicular substance ap- 

 peared to have been destroyed ; the structure of the cord up to the 

 point of junction with the abdominal tumour was normal. The abdo- 

 minal growth was for the most part firm, glistening on section, and 

 here and there showed evidence of haemorrhagic infiltration.

CARCINOMA OF THE KIDNEY IN A HORSE. 



203. An eight-year-old half-bred bay gelding. 



History. — Four months before examination the animal seemed to be 

 easily fatigued, and had fallen away in condition. When turned out 

 to grass it wasted rapidly, and swellings appeared under the belly, in 

 the sheath and hind limbs. On the right side the asternal ribs were 

 outwardly displaced, apparently by some abdominal growth. Pulse 

 50, weak ; temperature ioi° F. During the subsequent stages the 

 temperature varied between ioi° and 104° F. 



Diagnosis. — Enlarged liver. 



Slaughter was advised, but a delay of some weeks occurred before 

 the advice was put in practice. 



Post-mortem examination showed the right kidney to be enormously 

 enlarged. It was attached above to the psose muscles, on the right 

 to the abdominal wall, and below to the double colon. Before incision 

 it weighed seventy-nine pounds, and measured four feet six inches in 

 circumference. The left kidney was nearly double its ordinary size, 

 but otherwise normal. 



Microscopical examination showed that the mass was almost entirely 

 composed of a carcinomatous new growth, with a small amount of 

 stroma and epithelial cells of the spheroidal or glandular type.

MAMMARY ADENOMA IN THE BITCH WITH PULMONARY 

 METASTASIS. 



204. A collie bitch suffering from a tumour about the size of a 

 hen's egg in the mammary gland. Removal was not attempted. The 

 patient had been unwell for about a week, but dyspnoea only appeared 

 two or three days before death, and did not become distressing until 

 twenty-four hours before the end. 



On autopsy both lungs were found to be enlarged, and did not 

 collapse on opening the chest. The surface of the visceral pleura was
