DISEASES OF THE HOESE. 507 



their area of invasion. The alterations of meningitis and lamiiiitis are 

 identical with those of sporadic cases of founder and iniiamniation of 

 the brain. 



Treatment. — While the appetite remains the patient should have a 

 moderate quantity of sound ha}^, good oats, and bran; or even a little 

 fresh clover, if obtainable, can be given in small quantities. It is not 

 so important that a special diet shall be observed as that the horse shall 

 eat a moderate quantity of nourishing food, and he may be tempted 

 with any food of good quality that he relishes. The sick horse slioukl 

 be placed in a well-ventilated box stall away from other horses. 

 Grass, roots, apples, and milk may be offered and, if relished, allowed 

 freeh'. To reduce the temperature, the safest simple plan is to inject 

 large quantities of cold water into the rectum. Antipyrene may be 

 used with alcohol or strj^clmia. Derivatives in the form of essential 

 oils and mustard poultices, Imths of alcohol, turpentine and hot water, 

 after which the animal must be immediately dried and blanketed, 

 serve to waken the animal up from the stupor and relieve the conges- 

 tion of the internal organs. This treatment is especiall}^ indicated 

 when complication by congestion of the lungs, intestines, or of tie 

 brain is threatened. Quinine and salicylic acid in 1-dram doses wil. 

 lower the temperature, but too continuous use of quinine in some cases 

 increases the after depression. Iodide of potash reduces the excessive 

 nutrition of the congested organs and thereby reduces the tempera- 

 ture; again, this drug in moderate quantities is a stimulant to the 

 digestive tract and acts as a diuretic, causing the elimination of waste 

 matter by the kidneys. Small doses of Glauber's salts and bicarbon- 

 ate of soda, used from the outset, stimulate the digestive tract and 

 prevent constipation and its evil results. 



In cases of severe depression and weakness of the heart, digitalis 

 can be used with adv^antage. At the end of the fever, and when con- 

 valescence is established, alcohol in one-half pint doses and good ale in 

 1-pint doses maj^ be given as stimulants; to these may be added 1-dram 

 doses of turpentine. 



In complication of the intestines camphor and asafetida are njost 

 frequently used to relieve the pain causing the colics; diarrhea is also 

 relieved b}^ the use of bicarbonate of soda, nitrate of potash, and 

 drinks made from boiled rice or starch, to which may be added small 

 doses of laudanum. 



In complication of the lungs iodide of potash and digitalis are most 

 frequentl}^ indicated, in addition to the remedies used for the disease 

 itself. 



Founder occurring as a complication of influenza is difficult to treat. 

 It is, unfortunatel}^, frequently not recognized until inflammatory 

 changes have gone on for some days. If recognized at once, local 

 bleeding and the use of hot or cold water, as the condition of the ani-
