drops of the wine of ipecacuanha. If it is rejected 
by vomiting before it has had time to act, mix from 
twenty to sixty drops of tincture of opium in a lit- 
tle thin starch gruel and give as an injection per 
rectum. If this does not stop it give hypodermic- 
ally one-sixth of a grain of morphea in twenty 
drops of pure water. One drop of creosote at a 
dose and repeated if needed is sometimes very use- 
ful. Some place great confidence in chloroform 
in doses of from five to twenty drops. This may 
be tried if the others fail. 
MORBID APPETITE. 
There are two forms of this derangement: first, 
an animal may eat enormous quantities of food 
and still not be fat; second, it may eat unusual sub- 
stances. In the first case the animal should be al- 
lowed only a reasonable quantity of good food for 
several weeks until the stomach becomes accus- 
tomed to it. The second form is usually called de- 
praved appetite (Pica). In this disorder there is a 
desire, which seems to be irresistible, for sub- 
stances wholly unfit for food. This is often a 
habit, but may be caused by some deranged state 
ofthe stomach. The desire for earths, lime, stone, 
etc., would indicate that the animal’s stomach was 
in an acid condition. 
Treatment: In the first case regulate the food 
so that the animal cannot get too much. The 
stomach and bowels are usually in a weakened 
condition and require toning up, which is best done
