is easily rendered soft and
pliant in warm water; and by this peculiarity and its property of
adhering like glue, large plates of horn can be made by cementing
together the edges of small pieces rendered flat by a peculiar process,
as a substitute for glass. Imitation of tortoise-shell can be given to
horn by means of various metallic solutions. Horn, also, when softened,
can be imprinted with any pattern, by means of dies.

Diseases and their Remedies

Under this head it is proposed to notice such diseases as are most
common among cattle, together with their symptoms, and to suggest such
treatment of the same as has been found in the practice of the author,
in the main, effective. He is aware that much more space might have been
appropriated to this head, as has been the case in other treatises of
this class; but he doubts the propriety of multiplying words about
diseases which are of very rare occurrence, deeming it more fitting to
leave such instances exclusively to the intelligent consideration of the
reliable veterinary practitioner.

For convenience of reference, the diseases here noticed have been
arranged in alphabetical order; the whole concluding with information as
to two or three operations which cannot be uninteresting to, or
unprofitable for, the reader.

ABORTION.

The cow is, more than any other animal, subject to abortion, or
slinking, which takes place at different periods of pregnancy, from half
of the usual time to the seventh, or almost to the eighth month. The
symptoms of the approach of abortion, unless the breeder is very much
among his stock, are not often perceived; or, if perceived, they are
concealed by the person in charge, lest he should be accused of neglect
or improper treatment.

The cow is somewhat off her feed--rumination ceases--she is listless and
dull--the milk diminishes or dries up--the motions of the foetus
become more feeble, and at length cease altogether--there is a slight
degree of enlargement of the belly--there is a little staggering in her
walk--when she is down she lies longer than usual, and when she gets up
she stands for a longer time motionless.

As the abortion approaches, a yellow or red glairy fluid runs from the
vagina (this is a symptom, which rarely, or never, deceives) her
breathing becomes laborious and slightly convulsive. The belly has for
several days lost its natural rotundity, and has been evidently
falling,--she begin
