Against alkalies there does not exist the same objection; carbonate of magnesia, carbonate of soda or of potash may, in quantity, be mixed with gruel and horned down; both opium and ether may be blended with the drink. Should the pulse be low, a drachm of carbonate of ammonia may be added to each dose of the other ingredients. Should corrosive sublimate be in any degree suspected to be the agent employed, mix one dozen eggs with the other components; these will in no way detract from the operation of the drench. The mixture should be given in as large quantities as the animal can be induced to swallow. The gruel should be quite cold, and one quart should constitute a dose. No bleeding should be permitted the abstraction of blood promotes absorption; to prevent the absorption of the poison is the present endeavor. The following draught contains all that can be recommended, so long as ignorance of the actual poison it is desired to counteract, exists. When the information is positive, of course Morton's Toxological Chart will be a far better guide than any observations the author has ability to offer. Sulphuric ether and tincture of opium Of each three ounces. Carbonate of magnesia, of soda or potash Four ounces. Gruel (quite cold) One quart. To these may be added, should the pulse be of a sinking character:-- Carbonate of ammonia One drachm. If corrosive sublimate is known to have caused the agony, one dozen raw eggs ought to be blended with the drench. Use discretion in the administration; but repeat the drinks as often and as quickly as can be accomplished without adding to the distress of the horse. Regard the state of the animal, and, if weakness be present, take time when giving the drench. Should delirium be displayed, do not trust to the natural functions; employ Read's pump, with the horse catheter attached, and inject, with all dispatch, the whole quantity at once through the nostril. [Illustration: HOW TO GIVE PHYSIC, WHEN THE USUAL MODE OF ITS EXHIBITION IS ATTENDED WITH DANGER.] The symptoms of poisoning are various; they are also modified by the strength upon which they act. The annexed list, however, contains the general appearances by which poisoning is announced, though the whole of the symptoms are never simultaneously exhibited: Loathing of all food; extreme thirst; redness of the nasal and conjunctival membranes; discharge of ropy saliva; frequent eructations, which smell pungently fetid; colic, rolling on the ground, pawing, striking at the abdomen, etc.; tucked-up flanks; heaving; panting; small, quick pulse; superpurgation; violent straining; passing of mucus in large quantities; protrusion and inflammation of the opening; glances at the abdomen; prostration of strength; convulsions; madness and death.
