groups of muscles, especially of the adductors of the hind limbs and 

 superficial gluteal muscles ; nodules in the liver and spleen, and hyper- 

 trophy of the sublumbar lymphatic glands. Bacteriological examina- 

 tion showed these lesions to be of tuberculous origin, though bacilli 

 were very scanty. 



Up to the present time only two cases of dermic and hypodermic 

 tuberculosis in the horse have been published. Excluding the lymphan- 

 gitis and inflammation of lymphatic glands, the symptoms are those of 

 subcutaneous sarcoma — a disease which formed the subject of a previous 

 lecture, but is also very rare. 



The case I am about to mention is exceedingly instructive from the 

 clinical point of view. It is shortly as follows. 



At the commencement of May last we received into hospital a very 

 well nourished seven-year-old entire horse, bought in 1894, which had 

 done excellent service for nearly two years, viz. until February, i8g6. 

 It had simply shown swelling of the scrotum. As, however, the 

 swelling increased in size until finally it interfered with the action of 

 the hind limbs, the animal was brought here to be castrated. 



On examination we detected chronic inflammation of the right 

 testicle and its envelopes. The animal not having reacted to mallein, 

 castration was performed. The testicle, enlarged to three times its 

 normal dimensions, was removed with the ecraseur ; its parenchyma 

 had undergone httle change; the head of the epididymis was as large 

 as an orange, its tissue whitish and sclerosed ; the cord was healthy, 

 except that its serous covering was dotted over with reddish granula- 

 tions varying in size between that of a millet seed and a small pea. 

 These granulations were regarded as innocent inflammatory products. 

 Considerable swelling occurred round the wound, but soon became 

 absorbed, and the wound itself appeared to heal regularly. 



At the owner's request the other testicle was removed fifteen days 

 after the first operation, the ecraseur again being employed. It was 

 about one third larger than normal, the vaginal tunic contained a little 

 lemon-coloured liquid, the cord was slightly swollen, and its serous 

 covering partly dotted over with granulations like those seen on the 

 former occasion. 



During the following days the general condition and appetite were 

 good. Nevertheless fever was marked, the temperature rising nearly 

 to 40° C. (104° F.). The scrotal swelling was large. This condition 

 persisted for a week without any appreciable change except that the 

 animal became rather thinner. One morning, however, the horse was 

 found dead in its stall. On the previous evening it had eaten all its 

 food, and the student in charge had noted nothing alarming.
