those of the dog being liable to suffer. Throwing cold 

 water over the animals is quite unnecessary, because if 

 the dog be restored to its natural position separation may 

 in a short time be effected without difficulty. Copulation 

 is prolonged, not only to allow an ample amount of semen 

 to gradually be expelled from the epididymis and vas 

 deferens, but also to secure free evacuation of the secre- 

 tions of the highly developed prostate. 



Posthitis, inflammation of the glans penis, has already 

 been dealt with in discussing gonorrhoea, of which it is a 

 very frequent accompaniment. It is denoted by constant 

 semi-erection of the penis, the glans of which is large 

 and heightened in colour, or the seat of slight vesicular 

 eruption around its base. There is constant irritation of 

 the part, and not unfrequently some paraphymosis. This 

 disease is attributed to debility, for it occurs in animals 

 which have recently recovered from severe disease, and 

 especially in high-bred pet dogs in which the constitution 

 is languid and the nervous temperament predominates. 

 The treatment is simply antiphlogistic ; with subsidence 

 of the inflammation the turgescence will pass off and 

 oedema of the prepuce be lessened, so that the parts will 

 resume their natural appearance. 



Warty Growths of a non-malignant character are not 

 seldom found on and within the prepuce, and sometimes 

 on the glans. We have no evidence as to the identity of 

 this with "sweeps' cancer" in man, although the appear- 

 ances are rather similar to simple cases of the latter. 

 The epithelial growths are confluent or separate^ and occa- 

 sionally form masses of a spongy character and somewhat 

 considerable size, probably what Blaine describes as 

 "Polypi of the Sheath." These fungous growths may 

 become ulcerated, generally in consequence of injury, and 

 a thin watery discharge, intermingled with blood, trickles 

 from them. Whenever, after expulsion of urine, a few 

 drops of blood are passed, the glans penis and lining 

 membrane of the prepuce should be examined for these 

 growths. They should be promptly treated by removal 

 of the larger ones with scissors or knife as required, and
