enema administered through an elastic catheter, and irritation and spasm 

 were controlled by sedatives administered by the rectum. The drugs 

 were mixed with about a drachm of warm starch, and injected with an 

 ordinary glycerine enema syringe. The most useful were belladonna, 

 morphia, ergot, cocaine, and iodoform. Ergot is the only one not 

 generally recommended for this condition, but the author regards it as 

 a valuable vascular sedative, especially for the genito-urinary system. 

 Two or more of the foregoing were usually given in combination — a 

 dose at night, and sometimes one or even two in the day. By such 

 means the dog was able to keep its bladder empty, or nearly so, with- 

 out much difficulty ; it had little or no cystitis, and the urine was 

 never ammoniacal. Occasionally when the bladder, which was care- 

 fully watched, became distended it was emptied with a catheter. 



It was decided if the symptoms could no longer be kept in check 

 bv the above means, that as there was a possibility of an impacted

stone, the abdomen should be opened above the pubes with the strictest 

 antiseptic precautions, and if the case proved hopeless an overdose of 

 chloroform should be given ; but if an impacted stone were found it 

 should be removed by a supra-pubic lithotomy, and the animal given 

 a chance of recovery. 



It occurred to Mr. Clarke that, considering the small calibre and 

 great length of the dog's urethra, and the probability of hypera^mia of 

 the corpus spongiosum after an operation, which would render free 

 access to the bladder and regular catheterisation difficult, it would be 

 a great advantage to establish artificially a shorter route. A perinaeal 

 listula is usually a curse to its owner, but this arises from the fact that 

 it is usually associated with advanced vesical mischief, loss of control 

 over the sphincter, and the constant dribbling away of ammoniacal
