CANCER OF THE TESTICLE — UNSUCCESSFUL ATTEMPT TO INOCULATE. 405 



remove the left, which was retained in the abdomen. A ventral hernia 

 had developed beneath the second operative wound. 



On the 5th May the animal was fixed on the table and chloro- 

 formed. After disinfecting the parts M. Almy made an incision of 

 about three quarters of an inch in the long axis of the hernia, dividing 

 the subcutaneous tissue and afterwards opening the hernial sac. The 

 left testicle was found at the entrance to the pelvis, was withdrawn, 

 and removed by torsion. The muscular wound was closed by inter- 

 rupted silk sutures, and the cutaneous incision by sutures of silkworm 

 gut. The wound was painted with collodion containing salol, and the 

 abdomen covered with a dressing. 



On the loth the dressing was removed. The wound only contained 

 a little blood-stained serosity. 



On the 13th the sutures were cut and removed : two thirds of the 

 wound had healed. During the following days the parts were simply 

 washed with an antiseptic solution. The animal left hospital on the 

 19th May. 



CANCER OF THE SCROTUM. 



113. A seven-year-old setter dog, left in hospital 15th October, 

 1898. 



Had suffered for four months from a tumour on the scrotum, which 

 had become ulcerated, and had been unsuccessfully treated by cauteri- 

 sation with nitrate of silver. 



State on Entry. — The tumour appeared as a rounded, reddish patch 

 the size of a two-shilling piece, covered with fine granulations, slightly 

 painful on touch, sharply defined, and with hardened margins. From 

 a distance, and at the first glance, it resembled a patch of moist 

 eczema, but on closer examination its nature was clearly apparent. It 

 was in fact an ulcerated cancer. The inguinal glands were not 

 infected, and the animal's general health was good. 



Treatment. — On the 17th October the tumour was removed. The 

 region having been prepared and disinfected, complete excision, without 

 injury to the deeper structures of the scrotum, proved easy, as the new 

 growth only extended to the superficial layer of the dartos muscle. 

 The lips of the wound were united with silk sutures, and a cotton- 

 wool dressing, kept in position by a bandage, was applied. Despite 

 the precautions taken, the centre part of the wound suppurated, and 

 was not completely healed until the 4th November. 



The animal left hospital on the 8th. Recovery was perfect. There 

 was no return. 



The tumour was a lobulated epithelioma. Sections stained with 

 picro-carmine appeared formed of a more or less abundant fibrous 

 stroma, enclosing masses of newly formed epithelial cells and epidermal 

 " nests." 



CANCER OF THE TESTICLE— UNSUCCESSFUL ATTEMPT TO 



INOCULATE. 



114. A ten-year-old entire horse, entered hospital on the 4th Feb- 

 ruary, 1898. During the previous four months the right testicle had 

 progressively increased in size.
