and it is not noc*essai\y to refer to the subject again, ex- 

 cept to urge that no animal be purchased from any herd 

 where the disease prevails, or has been known to exist 

 in enzootic or epizootic form. Equal care should be ex- 

 ercised over the bull's patronage where the disease i« 

 suspected in the vicinity. 



After the disease has appeared in the herd the affected 

 animals should be isolated, at any rate given a special 

 corner in the barn to themselves. And immediately after 

 the bull serves an infected cow the penis and prepuce 

 should be thoroughly disinfected. 



The different methods of treatment have given uncer- 

 tain results : 



1. Efforts have been made to control the disease by 

 injecting small quantities of some antiseptic, like car- 

 bolic acid, under the skin at long or short intervals, or 

 by requiring the animal to consume such remedies with 

 the food. But it is quite probable the only good accom-

 acquired immunity. 



2. Flushing the womb with solutions of disinfectants 

 have not been attended with the results expected. Per- 

 sons who have applied these remedies with the great '.'st 

 care and thoroughness have been surprised to see the dis- 

 ease appear again in the subjects treated. We have al- 

 readv considered the structure of the female generative 

 organs, and it is readily understood how the germ in- 

 habitinir tlu^ deener portions of the womb, cut off from 

 the outer portion with the exception of a small opening, 

 the OS uteri (7), could escape the most thorough effort 

 to apply remedies in such manner as to be efl&cient. 



3. Attempts to stamp out the disease by means of 

 antiseptics has met with so little success that some writ- 

 ers have recommended the slaughter of all animals af- 

 fected. Disposing of the animals with a vicAv to pur-
