700 PATHOLOGY OF PARTURITION. 



syphon, or a piece of thick carbohsed catgut, introduced. Zundel 

 mentions that Liithi and Strebel have been very successful by this 

 method of operating. 



In all cutting operations on the teat, every precaution must be adopted 

 for the prevention of mastitis ; and this must chiefly consist in follow- 

 ing out the antiseptic method of treatment of the incisions as closely as 

 possible. 



Fistula of the Teat. • 



We have seen several cases of fistula of the teat which proved very 

 troublesome to cure during the period of lactation. From injury or 

 disease, an opening is established between the milk sinus and the side 

 of the teat ; so that the milk, instead of passing through the canal in 

 the extremity, escapes in a jet at the side, and its flow is nearly con- 

 stant. This is a source of loss, and has often an unpleasant appearance. 

 If it is decided to cure the fistula during the lactation period, and the 

 opening is towards the middle of the teat, then the ring teat-syphon 

 must be kept in the sinus for some time, and the fistula treated accord- 

 ing to surgical principles. When the fistula is towards the extremity 

 of the teat, however, the case is more difficult, and the teat-syphon only 

 too often renders it worse. Then it is generally necessary to wait until 

 the Cow is " drj'," when, with a little attention, the fistula is readily 

 cured.
