LIVER OF ANTIMONY—is a medicine possessing a very powerful and active property; and would not have been introduced in this place, but with a view to _prevent_ some of the MISCHIEFS which would probably happen, from too free a use of so dangerous an article, when in the unrestrained hands of the illiterate, the injudicious, the unthinking, or the inexperienced. It will create some surprise with the considerate, that this preparation, (known also by the name of CROCUS METALLORUM,) from _two_ to _six_ grains of which will operate as a violent _emetic_ with an adult of the human species, should be given in doses of _half an ounce_ each by common farriers to a horse, and that probably _three_ or _four_ times in twenty-four hours; under an impression, that it would, and does operate _only_ by perspiration, or as an alterative; beyond which, probably, their ideas or intentions may not extend. When it is taken into consideration, that the horse does not possess the power of regurgitating by _vomit_, it then becomes a matter of due deliberation, how far it may be consistent and proper, to permit valuable horses to be drenched with medicines of this description in such immoderate quantities; a very _few grains_ of which will excite such violent operations with one of the human species. Those who administer it as an ALTERATIVE, will, perhaps, prudently conceive, two drachms a day, in doses of a drachm each, full as much as ought to be ventured upon, incorporated with such other articles as the urgency of the case may seem to require. LIVER.—The liver in a horse is liable to disease, as obstructions by tubercles, indurated tumefactions, and schirrosity; either of which may be produced by various means, and treated as JAUNDICE, which SEE. LOCKS—are elastic leather pipes, or circular pads, stuffed with does' hair, about the size of a second finger in circumference, and made to buckle just above the fetlock of either leg, as a preventive to cutting with the other. There are others of a different form, made flat, having a padded oval in the center, which are called cutting-boots: the former, however, have the preference, as they occasion less stricture upon the tendons.
