The Cause. There is no question but what this disease is 

 caused by a germ which has been described by Nocard and Bang. 

 This germ cannot be killed very readily and on account of it be- 

 ing in the discharge from the vagina and also on the male ani- 

 mal it is important that the stalls and floors be thoroughly dis- 

 infected and that the bedding which may have been contaminat- 

 ed be burned and also the foetus. Cows affected should be iso- 

 lated and should have one attendant who does not take care or 

 come in contact with the healthy cows. It is important that one 

 person be assigned to the affected herd and use the necessary pre- 

 cautions so that he does not walk into the stables where healthy 

 cows are kept. Before he leaves the infected herd he should 

 thoroughly disinfect himself and leave the infected garments in 

 a suitable place so that they can do no harm. If a cow aborts in 

 the main stable she should be immediately removed and the prem- 

 ises should be as carefully disinfected as possible, using a strong 

 lye solution with plenty of hot water and a five percent solution 

 of carboHc acid. The most painstaking disinfection should be at 

 once commenced. The animal in the quarantine pen should be 

 treated immediately as follows : If the afterbirth has not come 

 away within five to eight hours it should be taken away by one 

 who knows how to perform this operation. The animal should 

 then be irrigated with a two percent solution of permanganate of 

 potash and the Hmbs and tail, etc., should be washed with soap 

 and water, and then with this permanganate of potash solution. 

 One capsule containing oil and kreso is then placed into the va- 

 gina which dissolves and disinfects the vagina. The vagina 

 should be irrigated every day with this permanganate of potash 

 solution and a capsule inserted. In addition to this the cow 

 should be fed carbolic acid in the feed. The carbolic acid 

 should be prepared as follows : Crude carbolic acid is liquified and 

 a small amount of glycerine is added to this to keep it in liquid 

 form. You start in by mixing with the bran, two drams of this 

 solution and then gradually increase the dose until about 6 drams 

 have been given a day. This is increased according to the viru- 

 lence of the disease. Best results have been obtained by giving
