How of milk ; the latter may be due to lack of removing 

 all the milk; jilso "caked bag" or mammitis may be a 

 sequel to lack of removing all the milk. Moreover, there 

 is some danger to non-immune milkers and possibly to 

 non-vaccinated children. 



Treatment consists in isolating the affected cows and 

 allowing the same milker to milk the diseased cows and 

 no others. The milker should keep his finger nails cut 

 close and smooth and thoroughly wash and disinfect his 

 hands after and before milking with a 2 per cent, solution

Tannic acid 1 ounce; 



Salicylic acid 4 drams ; 



Vaseline 3 ounces.

 children. Apparently it has no bad effects on calves not 

 alowed to suck. 



Varicella or false cow pox is characterized by having 

 single celled vesicles and hj its rapid course, passing 

 through the papular, vesicular, pustular and healing 

 stages in six to twelve days. The scab or crust is thinner 

 and not depressed in its centre as in cow pox. The ves- 

 icles and pustules have the same outline as those of cow 

 pox, but are smaller in varicella than in cow pox. 



Notice that these are variations in degree rather than 

 in kind; this makes it difficult to distinguish true cow 

 pox and false cow pox in some instances — especially in 

 the early stages. In varicella there may be successive
