changing their appearance—“bishoping” the teeth. For instance, a three- 
year old may be made to appear older by drawing the teeth which would 
soon drop out, thus allowing a more rapid growth to the permanent teeth; 
ora cavity is cut into the surface of the corner teeth and darkened with 
a hot iron or other means, to make a horse look younger. 
COLIC. 
This should not be mistaken for inflammation of the bowels (enteritis), 
or for stomach staggers. 
The following table will aid one in distinguishing 
it from the former, as well as from other disorders. 
ENTERITIS. 
The attack comes on gradually; restless- 
ness and fever-symptoms being present five 
or six hours before the violent symptoms. 
Pain continuous, with but slight intervals 
of comparative ease. 
Pressure on the abdomen gives pain. 
The pulse quick and full, or hard and 
thready; as the disease advances, rising to 
double the number of beats, or even more. 
The extremities cold. 
COLIC, 
The pain comes on suddenly, without 
any symptom, and is violent from the first. 
Pain comes on in paroxysms, with 
marked intervals of ease. 
Pressure or friction on the abdomen 
gives relief. 
The pulse not affected, except during the 
paroxysms of pain, or after the latter has 
continued some time. It is thus variable; 
sometimes natural, at others small and 
feeble, then full and quick. : 
The extremities warm. 
Colic is of two kinds, the spasmodic and the fatulent or windy, and the 
two kinds require separate description and treatment. 
SPASMODIC COLIC. 
This form is caused by impure air and irregular exercise, with dry, poor 
food and insufficient water. It is aggravated or excited by sudden chills, 
chiefly after hard work; free drinking of cold or mineral water; constipa- 
tion; gritty lumps in the intestines; violent purging; green food in undue 
quantities. 
Symptoms of Spasmodic Colzc.—Severe pains in the abdomen coming 
on in paroxysms; the horse, in apparently previous good health, turns his 
nose toward the flanks with a frightened look, paws, and is uneasy. 
As 
yet the pulse is natural; an appearance of ease is now observed for a short 
period, then the symptoms return and are aggravated; the horse stamps
