dogs. The appearance
of the ascaris in the dog's stools is, of course, _the_ diagnostic
symptom.

_Treatment_--I have cured many cases with santonin and areca-nut
powder (betel-nut), dose 10 grains to 2 drachms; or turpentine, dose
from 10 drops to 1-1/2 drachms, beaten up with yolk of egg.

But areca-nut does better for tape-worm, so we cannot do better than
trust to pure santonin. The dose is from 1 grain for a Toy up to 6
grains for a Mastiff. Mix it with a little butter, and stick it well
back in the roof of the dog's mouth. He must have fasted previously
for twelve hours, and had a dose of castor oil the day before. In four
or five hours after he has swallowed the santonin, let him have a dose
of either olive oil or decoction of aloes. Dose, 2 drachms to 2 ounces
or more. Repeat the treatment in five days. Spratts' cure may be
safely depended on for worms. [1]

recommended as a cure for worms.--Ed.

The perfect cleanliness of the kennel is of paramount importance.

The animal's general health requires looking after, and he may be
brought once more into good condition by proper food and a course of
vegetable tonics. If wanted in show condition we have Plasmon to fall
back upon, and Burroughs and Wellcome's extract of malt.

There is a round-worm which at times infests the dog's bladder, and
may cause occlusion of the urethra; a whip-worm inhabiting the caecum;
another may occupy a position in the mucous membrane of the stomach;
some infest the blood, and others the eye.

(2) _Tape-worms_--There are several kinds, but the treatment is the
same in all cases. The commonest in the country is the Cucumerine.

This is a tape-worm of about fifteen inches in average length,
although I have taken them from Newfoundland pups fully thirty inches
long. It is a semi-transparent entozoon; each segment is long compared
to its breadth, and narrowed at both ends. Each joint has, when
detached, an independent sexual existence.

The dog often becomes infested with this parasite from eating sheeps'
brains, and dogs thus afflicted and allowed to roam at pleasure over
fields and hills where sheep are fed sow the seeds of gid in our
flocks to any extent. We know too well the great use of Collie dogs to
the shepherd or grazier to advise that dogs should not be employed as
assistants, but surely it would be to their owners' advantage to see
that they were kep
