 of the duct by contraction of its walls or by a membra-

 handle, but which can be pressed out of its case so as to 

 cut to any extent desired) and a silver or gutta-percha 

 teat tube to be kept tied in the newly made channel until 

 it heals. It is well to leave these surgical operations un- 

 til the milk is dried up. A simple instrument is in use 

 by dairymen, consisting of a steel probe flattened out to 

 two lines at one extremity and with finely sharpened 

 point. 



BOEE TEATS. SCABS. WAETS. 



Sores, chaps and scabs on the teats are to be treated 

 by soothing apphcations. One ounce each of spermaceti 

 and almond-oil melted together wiU often suffice. Or 5 

 grains each of balsam of Tolu or Peru may be added. 

 Or a solution of 5 grains of sugar of lead or chloral-hy- 

 drate and J oz. each of glycerine and water. But no plan 

 will succeed without gentle milking, with dry teats, espe- 

 cially in winter, or in bad cases without the use of a milk- 

 ing tube. Warts are to be removed by the knife, scissors 

 and caustic.

 are met with in all species of domestic quadrupeds and 

 demand removal with the knife.
