134 SPECIAL CATTLE THERAPY 



When the duct is dissected free from its surround- 

 ing's to the depth of half an inch, a catgut ligature is 

 applied around it, close to the proximal end. Just be- 

 fore the ligature is tied, the duct is swabbed with tur- 

 pentine, the latter for the purpose of setting up an irri- 

 tation to hasten the formation of adhesions. The ex- 

 ternal 'wound is treated as an injury and heals 

 promptly. 



Unless the operator has been unclean in this opera- 

 tion the results will be all that can be expected. 



The ligature requires no attention, and all trace of 

 the fistulous opening gradually disappears. The tur- 

 pentine swab must not be forced into the duct too far, 

 as in that event it may do harm in the glandular por- 

 tion. Some rudimentary teats appear to obtain their 

 duet directly from the acini instead of from the sinus 

 lactiferus.
