stand until a tinu curd has formed. This will require 10 to J^O minutes. 

 Break tlie curd up into several pieces, heat to the boiling point and filter 

 through cheese cloth. Place the whey in sterile fruit jars and sterilize 

 by setting the jars in a boiler of water and boil for about 30 minutes to 

 one hour each day for three consecutive days. When boiling for the 

 first time the tops and rubbers should be placed loosely on the jars but 

 as soon as the boiling process ceases the top should be immediately tight- 

 ened. At subsequent boilings the tops should be left undisturbed. It is 

 suggested that some old towels or a wooden rack be placed in the bot- 

 tom of the boiler to prevent the jars coming in contact with the bottom 

 of the boiler. Whey put up in this way can be kept almost indefinitely. 

 When desired for use, take that quantity of whey needed for two days' 

 treatment and add a culture of the lactic acid organism and set in a 

 warm place. In one to two days, enough acidity should have developed 

 for use. Occasionally the lactic acid organisms fail to grow in whey, 

 therefore it should always be tasted before using. A sour taste indicates 

 that the organisms have been active. 



Method of injections. After abortion the injection should be made 

 into the uterus. The best way for the inexperienced man to accomplish 

 this is to secure a piece of rubber tubing about 4 or 5 feet long and lA 

 inch in diameter or a fiber male (horse) catheter. Attach one end of 

 either tube to a tin or glass funnel and into the other insert a metal 

 (aluminum) tube about 14 to 16 inches long. If the rubber tubing is 

 rather stiff (or if the catheter is used) it will not be necessary to use 

 the metal tube. Introduce the hand into the vagina a distance of about 

 8 to 10 inches and locate the mouth of the uterus. Then introduce the 

 metal tube through the mouth into the uterus. An attendant now pours 

 the solution into the funnel, raises it and allows it to gravitate into the 

 uterus. This treatment should be given every day as long as the mouth 

 of the uterus is sufficiently open for the tube to be introduced without 

 difficulty, then vaginal injections should be given two or three times a 

 week until the uterine and vaginal discharges have ceased. During the 

 treatment, the external genitals, buttocks and tail of the animal should 

 be kept clean by washing with some disinfectant. 



Treating the genital organs of the cow after abortion is a matter of 

 very great importance. Drastic or improper treatment is more injurious 

 than no treatment at all. Many coavs have been made sterile and others 

 have been killed by drastic treatment. 



In the first place the hand should not be forcibly introduced through 

 the mouth into the uterus. For a time after delivery the mouth of the 

 uterus is sufficiently open to admit the hand without difficulty. It grad-' 

 ually closes, the time required depending upon the course of the diseased 

 process in the uterus, until the hand cannot be introduced without force. 

 Before introducing the hand the finger nails should be cut short and 

 cleaned, the hand should be scrubbed with water and soap and then 

 washed in a 1 to 50 solution of compound solution of cresol or 1 to 1000 

 solution of bichlorid of mercury. 



Importance of selecting proper antiseptic. The selection of a solu- 

 tion for irrigation of the genital passages and the quantity to be used 

 is not a matter of indifference. Let it be emphasized that a disinfection 

 of the mucous membranes of the genital passages by strong disinfect-
