the tail. Being very poisonous, it should be kept in a wooden barrel 

 out of the way of animals or children. Every morning the vulva, anus, 

 the back of hips, and root of tail should be sponged with this liquid, 

 and this is best applied to the whole herd. 



3. When any case of abortion has occurred the fetal membranes must 

 be removed b}' the hand without delay, and together with the fetus de- 

 stroyed by burning, or buried deeply, and the stall should be cleansed 

 and watered with the proper solution. Then the womb should be 

 washed out with one and one-half gallons of corrosive sublimate solution 

 injected through a rubber tube introduced to the depth of the womb 

 and with a funnel in its outer elevated end. This should be repeated 

 daily for a week. In the case of the other cows of the herd one injec- 

 tion of the same kind should be made into the vagina, after which they 

 need only have their external parts and tail washed with the solu- 

 tion daily. 



As a certain number of the cows will harbor the germ in the womb 

 when treatment is started, it is not to be expected that the abortions 

 will cease at once, but by keeping up the treatment the trouble may be 

 gotten rid of in the following year. As an aborting cow is usually of 

 little use for the dairy, it is best to separate and fatten her and apply 

 treatment to remaining cows. In this as in other delicate manipulations, 

 the stockowner will consult his own interest by employing an accom- 

 plished veterinarian, and avoiding such as have not had the privilege of 

 a thorough professional education. In addition to the above the removal 

 of all manure and contaminated litter and the immediate sprinkling of 

 the surface with the sulphate of copper solution is called for. Drains 

 should no less be thoroughly rinsed and disinfected. Mill ing stools and 

 other implements may be treated in the same way, or with carbolic acid 

 or boiling water. Great care should be taken to guard against bull or 

 cows from an aborting herd or district; streams even may be suspected 

 if there is an aborting herd near by and higher up on that stream. 

 Cows sent to bull from an aborting herd are to be denied, and workmen 

 that have attended on such a herd should be made to wash and disinfect 

 their clothes and persons. 



Duration of Pregnancy. From extended statistics it is found 

 that the average duration of pregnancy in the cow is two hundred 

 eighty-five days. A calf born at the two hundred fortieth day may 

 live, and a case is reported by Deitrichs of a calf born on the three hund- 

 red thirty-fifth day, and another by the American Journai, of
