erfectly cold.
Either of the following may be administered:--

1.

Tincture of cantharides One drachm.
Camphor mixture One pint.

2.

Tincture of nux vomica One drachm.
Tincture of tolu One drachm.
Water One pint.

3.

Tincture of cubebs One drachm.
Liquor potassae One drachm.
Camphor mixture One pint.

4.

Solution of nitrate of silver One drachm.
Distilled water One pint.

Any of the above may be employed, from a tablespoonful to a common
wine-glass full being used for a dose. The pile ointment will likewise be
beneficial, by facilitating the passage of the faeces, allaying local
irritability, and correcting that tendency to piles which is generally
attendant upon, if not the original cause of the affection.

From what has been described, the reader will have seen that the diseases
of the dog's rectum are neither few nor insignificant. Fistula in ano is
said to be often beheld; but I have never seen a case in which it assumed
in the dog that serious form which characterises it in man. In the canine
race I have mostly let it alone, and hitherto I have had no reason to
repent my forbearance. Blaine and Youatt both speak of the affection, and
give directions for its treatment by operation. The most active remedy I
have found it necessary to resort to has been an astringent or mildly
caustic injection; the solution of the chloride of zinc I prefer to every
other, but the sulphates are also not to be despised. Injections, when not
designed to be immediately operative, or meant to distend the gut and to
act through being ejected, are best given by means of the India-rubber
bladder, which allows the fluid to be more gently and silently thrown up.
The less noise or force attending the operation the less likely is the
animal to be alarmed or excited, and the probability is the enema will be
retained. Small quantities are to be administered when the fluid is wished
to remain; and by attracting the attention of the dog at the time, and
amusing him after the business is finished, the object in view is
considerably favored. The administration of an injection is in the first
instance almost certain to alarm the animal, who can neither understand
nor passively sanction the strange liberty the operation implies. A little
