Diarrhea 275 
of light sorrel, buckskin or dun color are more subject 
to diarrhea than those of more decided colors. 
As diarrhea is an effort of nature to remove an 
irritant, it follows that it should not be checked too 
suddenly. First, locate and remove the cause. A small 
dose (about two ounces for horses and cattle, and a 
half ounce for calves) of castor-oil combined with an 
ounce of landanum, and given as a drench with a little 
linseed gruel is excellent. For calves and lambs, a 
small quantity of dried blood (one teaspoonful to one 
tablespoonful), given in dilute milk or gruel three times 
daily, will usually stop the trouble. For calves, it is 
usually a good plan to dilute the milk with one-third 
lime-water, and to feed them frequently, but only small 
amounts at a time. Parched flour added to boiled or 
sterilized milk is also advisable. Lime-water can be 
made by pouring water on fresh lime. After the 
lime is slaked and settled, the water can be poured 
off and used. Equal parts of essence of Jamaica ginger, 
laudanum, and tincture of asafetida, mixed and given in 
hot water as a drench, is excellent. The dose is from 
two teaspoonfuls to two tablespoonfuls of the mixture. 
In persistent cases, use an astringent, such as oak-bark 
tea. This is made by steeping the inner bark of white 
oak. For a horse, a teacupful of this tea combined 
with an ounce of landanum should be given as a dreneh 
twice daily. Horses that are subject to diarrhea while 
on the road should be watered sparingly before and 
during the drive. Prepared chalk in one-half to ounce 
doses twice daily is useful in such cases,
