to a quarter of a pound, in a
quarter of a pint to a quart of water--may be administered. A more active
injection will be, from half a drachm to four drachms of turpentine,
beaten up with the yolks of so many eggs as there are drachms of the oil,
and mixed with the quantity of water just named.

Either of these will relieve the bowel; but the condition of one part
justifies an inference as to the state of another, and the enema probably
will not unload the caecum, which there is reason to suppose is also
clogged. A gentle dose of castor-oil, or of the pills directed on page
116, will accomplish this intention; and, afterwards, measures must be
adopted to regulate the digestion, either by tonics or such medicines as
the symptoms suggest, but not by the constant repetition of laxatives.

Costiveness will sometimes produce such violent pain that alarm is
created, and dogs have been destroyed under the idea that they were rabid.
To guard against so fatal a mistake, I shall only here say, that rabies
does not come on suddenly, or, save in the latest stage, appear to
influence the consciousness, which it never entirely overpowers. The agony
caused by costiveness is greater than in any other affection to which the
dog is liable. Apparently well, and perhaps at play, a cry breaks forth,
which is the next instant a shriek, expressive of the acutest torture. The
animal takes to running, and is not aware of surrounding objects; it can
recognise nothing, but will bite its master if he attempts to catch it,
and hit itself against anything that may be in its way; it scampers from
room to room, or hurries from place to place; it is unable to be still or
silent; and perhaps getting into a corner, it makes continuous efforts as
though it wished to scramble up the wall, remaining there jumping with all
its strength, and at the same time yelling at the top of its voice. This
excitement may last for an hour or more, and then cease only to be
renewed: till at length the powers fail, and in half a day the animal may
be dead. Just prior to death, a mass of compact faeces is usually passed;
and blood, with dysentery, is generally witnessed for the short period the
animal survives. After death, general inflammation of the intestines is
discovered, and the dog is reported to have perished from an attack of
enteritis which no medicine could subdue.

In such cases, the first examination should be directed to the rectum; the
finger, moistened or
