THIRTY-SEVENTH ANNUAL CONVENTION. 137 



sure to take place. In treating animals for this disease it is well 

 to make a special vaginal syringe; a gravity apparatus is used 

 consisting of a large funnel, several feet of rubber tubing with a 

 canula attached. A rubber tube ten feet in length, 38-inch bore 

 and 3.4 inch outside diameter is to be recommended for both 

 vaginal and uterine irrigation used with a funnel, attached to any 

 enema pump, a pail or tank fitted with a stop-cock, or with a 

 sufficiently large tube holder and suction plate to keep it down 

 and prevent kinking. It is sometimes possible to suspend a large 

 pail above and behind the cows and to pull it along the shed ; 

 this facilitates the work very much in large herds and econo- 

 mizes the cowmen's time. The irrigations with mild solutions 

 are carried out twice daily for a few days, then once da*liy, be- 

 coming less frequent after two or three weeks. After washing 

 out the whole vaginal canal insert a Bissulin Capsule once daily 

 for a time, in capsule or pencil form; the pessary is best intro- 

 duced as far as possible with the fingers. 



It is absolutely necessary to prevent the animals from copu- 

 lating until all inflammtery pneumonia has disappeared, and 

 for a short time afterward, roughly six weeks. The irritation 

 sometimes produced by coition, even in the chronic cases, has 

 already been alluded to. Recovery is retarded, and infection may 

 be conveyed in this way. It is good practice to syringe out the 

 vagina with a one per cent solution of bicarbonate of soda be- 

 fore going to bull, in case an acid or neutral state of the mu- 

 cous exists ; the reaction should be feebly alkaline, and various 

 conditions of the genital tract may alter this. 



Little more need be said in regard to prophylaxis. If 

 the sound animals are few in number, and other premises are not 

 available, they should occupy stalls apart from the other cows to 

 which the drainage does not flow, e. g., at the higher end of the 

 shed. The sound cows should be dressed first, and all fresh ar- 

 rivals disinfected and kept under observation. A garden syr- 

 inge is useful for spraying the hind parts after cleansing the 

 soiled vulva and tail.
