By this term we are to understand such substances as will expel worms from the intestines of the dog, their action being either poisonous to the worm itself, or so irritating as to cause them to evacuate. All ought either to be in themselves purgative, or to be followed by a medicine of that class, in order to insure the removal of the eggs, as well as the worms themselves. More detailed directions will be fouad in the chapter of Worms.

Aperient-worm bolus.

64 - Calomel, 2 to 5 grains. Jalap, 10 to 20 grains.

Mix into a bolus, with molasses.

For general worms. Not aperient, and therefore to be followed by castor oil:

65 - Recently powdered areca nut, 1 to 2 drachms.

Mix with broth, and give to the dog directly, as there is no taste in it until it has been soaked some time, when the broth becomes bitter. If the dog refuses it he must be drenched. Four hours after, give a dose of castor oil. N. B. - The exact dose is 2 grains for each pound the dog weighs.

For round-worms, or maw-worms:

66 - Indian pink, 1/2 ounce. Boiling water, 8 ounces.

Let it stand for an hour, then strain, and give half to a large dog, a quarter to a middle-sized dog, or an eighth to a very small one. This, however, is a severe remedy, and is not unattended with danger. It should be followed by castor oil in six hours.

Mild remedy, unattended with any danger:
