Mammary Fistula is most frequently associated with 

 cancer. It has been mentioned in connection with 

 mammitis under the heading of Lacteal Fistula, but such 

 cases are very exceptional. The surgical treatment, when 

 the disease is not associated with cancer, is much the same 

 as in other forms of fistula. Injections of iodine are some- 

 times useful. 



Fistula in the Teat, though common in bovines, seldom 

 occurs in the bitch, and when it does so, the opening 

 usually takes place at the base of the teat. Lactation 

 retairds the treatment, and if the patient is suckling, it may 

 be necessary to wean the puppies, or wait until the bitch is 

 dry before adopting direct surgical treatment. 



Gastric and Biliary Fistulce being purposely promoted 

 for experimental purposes, need no description in this 

 work. 



EXCISION OF SEROUS CYST. 



In the early part of 1883 I was consulted by Mr. H. E. 

 Marston relative to a swelling in front of the throat of a 

 small, smooth white terrier called "The Colonel." The 

 enlargement proved to be a serous cyst, or abscess. The 

 contents were then evacuated with a trochar and canula, 

 and as I was informed it had preyiously been opened and had 

 refilled, I gave instructions with a view of preventing the 

 latter result. On the 14th of January, 1884, I received 

 another visit from Mr. Marston and "The Colonel," and 

 the old story of evacuation and refilling was once more 

 told. An examination revealed considerable enlargement 

 of the fruitful cyst, and, as a final measure, I recommended 

 its complete excision. So, on the i6th, "The Colonel" 

 came to my infirmary, and submitted with a nerve of iron 

 to the knife, the operation proving a long and tedious one.
