(J(5 DISEASES OP THE HORSE. 



make this chain of evidence complete, the poison may be discovered 

 in the organs of the horse by chemical analysis. In nearly all cases 

 of Castro-enteritis there is nervous depression. 



The poisons that are most irritant to the digestive tract are arsenic, 

 corrosive sublimate, sugar of lead, sulphate of copper, sulphate or 

 chloride of zinc, lye or other strong alkalies, mineral acids, and, 

 among the vegetable poisons, tobacco, lobelia, and water hemlock. 



The treatment will depend upon the cause, but if this can not be 

 detected, certain general indications may be observed. In all cases 

 food should be given in small amounts and should be of the most 

 soothing description, as oatmeal gruel, flaxseed tea, hay tea, fresh 

 grass, or rice water. The skin should be well rubbed with wisps of 

 straw and alcohol, to equalize the distribution of the blood; the legs, 

 after being rubbed until warm, should be bandaged in raw cotton or 

 with woolen bandages. The horse should be warmly blanketed. It is 

 well to apply to the abdomen blankets wrung out of hot water and 

 frequently changed ; or mustard paste may be rubbed on the skin of 

 the tally. Internally, opium is of service to allay pain, check secre- 

 tion, and soothe the inflamed membrane. The dose is from 1 to 2 

 drams, given every three or four hours. If there is constipation, the 

 opium should be mixed with 30 grains of calomel. Subnitrate of 

 bismuth may be given with the opium or separately in 2-dram doses. 

 Stimulants, such as alcohol, aromatic spirits of ammonia, or camphor 

 may ta given in 2-ounce doses, mixed with warm water to make a 

 drench. 



If putrid food lias been consumed, creolin may be administered in 



doses of ii drams, mixed with 1 pint of warm water or milk. If there 



.s obstinate constipation and a laxative must be employed, it should 



ta sweet or castor oil, from 1 pint to 1 quart. For the various 



poisons the remedies are as follows: Arsenic, oxyhydrate of iron 



solution, 1 pint to 1 quart, or calcined magnesia one-half ounce in 1 



pint of water; corrosive sublimate, the whites of a dozen eggs or 2 



ounces of flowers of sulphur; sugar of lead, Glauber's salts, 1 pound 



1 quart of warm water, to ta followed with iodide of potash, 3 



drains at a dose, in water, three times daily for five days; sulphate of 



'. milk, the whites of eggs, or reduced iron; sulphate of chlo- 



>.inc, milk, the whites of eggs, or calcined magnesia; lye or 



'c pot<i*h or *oda, vinegar, dilute sulphuric acid, and 



ith opium, 3 drams; mineral acids, chalk, or calcined 



sia, or baking soda ; later give linseed tea and opium.
