appetite, with increased temperature and cold extremities. Visible mucous
membranes are injected, pupils of the eyes are contracted, and there is a
watery discharge from the eyes and nostrils. Remotely it exerts a
depressing influence on the functions of the brain and slight coma, and
occasionally convulsions, from which the animal is easily aroused. The
kidneys also suffer. The urine is dark colored and has the characteristic
odor of coal oil. Death may result from gastroenteritis or convulsions.

_Treatment._--The patient's strength should be fostered by the frequent
administration of mild stimulants, of which aromatic spirits of ammonia is
perhaps the best. The animal should be encouraged to eat soft feed and
given mucilaginous drinks.

Crude coal oil is sometimes applied to the skin to kill parasites. If too
much is used, especially in hot weather, great weakness and depression may
be caused and in some cases death may result.

CARBOLIC-ACID POISONING.

Although one of the most valuable antiseptic remedies, carbolic acid in a
concentrated form, when taken internally or used over a large surface
externally, is likely to produce poisonous effects. It causes whitening,
shrinking, and numbness of the structures with which it comes in contact,
and, besides its irritant effect, exerts a powerful influence on the
nervous system. Being readily absorbed, it produces its effect whether
swallowed, injected into the rectum, inhaled, or applied to wounds, or even
to a large tract of unbroken skin. Used extensively as a dressing, it may
produce nausea, dizziness, and smoky or blackish colored urine. The last
symptom is nearly always noticeable where the poisonous effect is produced.
In more concentrated form, or used in larger quantities, convulsions,
followed by fatal coma, are likely to take place. Even in smaller
quantities, dullness, trembling, and disinclination for food often continue
for several days. In a tolerably concentrated solution it coagulates
albumen and acts as an astringent.

_Treatment._--As an antidote internally, a solution of sulphate of soda or
sulphate of magnesia (Glauber's or Epsom salt) may be given. The white of
egg is also useful. Stimulants may be given if needed. When the poisoning
occurs through too extensive applications to wounds or the skin, as in
treatment of mange, cold water should be freely applied so as to wash off
any of the acid that may still remain unabsorbed. As a surgical dressin
