Diseases of the Stomach, 63 
easily excited than in any other of the lower species. We 
have abundant proof of this in the administration of 
medicines, and in common observance during exercise, 
when their instinct teaches them to seek what is termed 
“ dog-grass,” the effect of which after swallowing is quickly 
manifested. 
Vomiting may be a symptom of disease, the result of an 
overloaded stomach, or the presence of irritating matters 
within it or applied to the fauces. or it may take place from 
cesophagal obstruction. Worms are a very frequent cause 
of vomition. (See “ Worms.”) 
The vomit may consist of mucus, bile blood, or food 
mingled with other offending matters. 
Vomiting is medicinally induced by agents termed 
“emetics,” the favourite one being tartarised antimony— 
and a dangerous one it ig when given injudiciously. 
Fortunately, however, the dog’s stomach, as previously ob- 
served, quickly responds to its call, and it is for the most | 
part thrown off; otherwise dogs would by quacks be killed 
by the score. If his more unfortunate companion, the 
horse, were equally capable of performing the same act, 
antimony would speedily cease to exist in the never-failing 
condition-powders of the groom and chemist. For all 
ordinary purposes, plain warm water or water in which (if 
immediate action be desired) a little salt and mustard is 
mixed, is sufficient; in fact, I have readily produced 
vomiting with the latter, when I have failed with antimony. 
The treatment of vomiting must be directed to the cause. 
WORMS IN THE STOMACH. 
Dogs are frequently troubled with worms in the stomach. 
Their presence gives rise to severe gastric disturbance, and 
is often productive of convulsions and death.

ing and vomiting, foetid breath, a dry, husky cough, ‘intesti-
