116 THE OEANGE COUNTY 



Poisons 



principally exert their influence. The yew is the most fre- 

 quent vegetable poison. The horse may be saved by timely 

 recourse to equal parts of vinegar and water ejected into the 

 stomach, after the poison has been as much as possible re- 

 moved by means of the stomach-pump. For arsenic or cor- 

 rosive sublimate there is rarely any antidote. 



Spasmodic Colic 



is too frequently produced by exposure to cold, the drinking 

 of cold water, or the use of too much green meat. The horse 

 should be walked about, strong friction used to the belly, 

 and spirit of turpentine given in doses of two ounces, with an 

 ounce each of laudanum and spirit of nitrous aether, in warm 

 water, ale or gruel. If the spasm is not soon relieved, the 

 animal should be bled, and injections of warm water with a 

 solution of aloes thrown up, if constipation exists. This spas- 

 modic action of the bowels, when long continued, is liable to 

 produce 



Introsusception, or entanglement, 

 of them; and the case is then hopeless. 



Superpurgation 



often follows the administration of a too strong or improper 

 dose of physic. The torture which it produces will be evi- 

 dent by the agonized expression of the countenance, and the 

 frequent looking at the flanks. Plenty of thin starch or 

 arrowroot should be given both by the mouth and by injec- 

 tion; and twelve hours having passed without relief being 

 experienced, chalk, catechu, and opium, should be added to 

 the gruel 



Worms 



in the intestines are not often productive of much mischief, 

 except they exist in very great quantities. Small doses of 

 emetic tartar or calomel, with a little ginger, may be given 

 to the horse half an hour before his first meal, in order to 

 expel the round white worm; it must be worked off with lin- 

 seed-oil or aloes, and injections of linseed-oil or aloes will 

 usually remove the ascarides, or needle-worms.
