alone, and agents given to cheek the excitement of the labor pains. 

 Laudanum in doses of 1 ounce for a small cow or 2 ounces for a large 

 one should be promptly administered and repeated in three or four 

 hours, should the labor pains recur. This may be kept up for days or 

 even weeks if necessary, though that is rarely required, as the trouble 

 either subsides or abortion occurs. If the laudanum seems to lack per- 

 manency of action use bromide of potassium, or better, extract of vibur- 

 num pruuifolium (40 grains) at intervals of two or three hours until 

 five or six doses have been given. 



Treatment of contagious abortion. So far as this differs from the treat- 

 ment of sporadic abortion, it consists in the free use of germicides or 

 disinfectants. 



(1) Scrape and wash the ba<jk part of the stall and gutter and water 

 it with a solution of 5 ounces sulphate of copper (bluestone) in 1 gallon 

 pure water. Kepeat this cleaning and watering at least once a week. 

 This should in all cases be applied to every stall where an aborting cow 

 has stood and to those adjacent. To treat the whole in the same way 

 would be even better, as it is impossible to say how many of the cows 

 harbor the germ. This is the more needful that in three or four years, 

 if the aborting cow is kept on, she becomes insusceptible and carries 

 her calf to full time. A cow may therefore be infecting to others though 

 she no longer aborts herself. 



(2) Dissolve 1 dram corrosive sublimate, 1 ounce each of alcohol and 

 glycerine, and shake this up in a gallon of water, to use as an injection 

 into the vagina and a wash for the parts about the vulva and root of 

 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, 

 back of the hips, and root of the tail should be soonged 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 by the hand without delay, and together with the fetus 

 destroyed by burning, or boiling, or buried deeply, and the stall should 

 be cleansed and watered freely with the copper solution. Then the 

 womb should be washed out with 1 gallons of the corrosive sublimate 

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

 womb and witli 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 injection of the same kind should be made into the vagina, after 

 which they need only have their external parts and tail washed with 

 the solution daily. 



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

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

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

 quit of in the following year. As an al>orting row is usually of little 

 use for the dairy, it is bct to separate and fatten her and apply treat-
