t in a state of health and cleanliness.

_Treatment_--We ought to endeavour to prevent as well as to cure. We
should never allow our dogs to eat the entrails of hares or rabbits.
Never allow them to be fed on raw sheep's intestines, nor the brains
of sheep. Never permit them to lounge around butchers' shops, nor eat
offal of any kind. Let their food be well cooked, and their skins and
kennels kept scrupulously clean. Dogs that are used for sheep and
cattle ought, twice a year at least, to go under treatment for the
expulsion of worms, whether they are infested or not; an anthelmintic
would make sure, and could hardly hurt them.

For the expulsion of tape-worms we depend mostly on areca-nut. In
order that the tape-worm should receive the full benefit of the remedy,
we order a dose of castor oil the day before in the morning, and
recommend no food to be given that day except beef-tea or mutton broth.
The bowels are thus empty next morning, so that the parasite cannot
shelter itself anywhere, and is therefore sure to be acted on.

Infusion of cusco is sometimes used as an anthelmintic, so is wormwood,
and the liquid extract of male fern, and in America spigelia root and
pumpkin seeds.

The best tonic to give in cases of worms is the extract of quassia.

Extract of quassia, 1 to 10 grains; extract of hyoscyamus, 1/2 to 5
grains. To make one pill. Thrice daily.

PARASITES.--EXTERNAL.

FLEAS.

Washing with Spratts' medicated soap. Extra clean kennels. Dusting
with Keating, and afterwards washing. This may not kill the fleas, but
it drives them off. Take the dog on the grass while dusting, and begin
along the spine. Never do it in the house.

TICKS.

I have noticed these disagreeable bloodsuckers only on the heads and
bodies of sporting or Collie dogs, who had been boring for some time
through coverts and thickets. They soon make themselves visible, as
the body swells up with the blood they suck until they resemble small
soft warts about as big as a pea. They belong to the natural family,
_Ixodiadae_.

_Treatment_--If not very numerous they should be cut off, and the part
touched with a little turps. The sulphuret of calcium will also kill
them, so will the more dangerous white precipitate, or even a strong
solution of carbolic acid, which must be used sparingly, however.

LICE.

The lice are hatched from nits, which we find clinging in rows, and
very tenaciously too, to the hairs. The insects themselves are m
