be distinguished by the gradual nature of tlie onset, by the ab- 

 sence of the conditions attending on the attack of hsemoglo- 

 binaeniia, and usually by the absence of haemoglobin, urea and 

 other nitrogenous products in excess in the urine. 



Prevention. The hard- worked or systematically exercised horse, 

 which is at the same time heavily fed must not be left in a state of 

 absolute rest in his stall for twenty-four hours. A fair amount of 

 exercise must be giv-en on every day in the week, and at the same 

 time, the food should be restricted in ratio with the restriction of 

 exercise. Turning for an hour or two daily into a yard may be a 

 sufficient precaution. When from any cause, rest- is imperative, 

 the diet must be materially reduced and given in part in a laxa- 

 tive form (bran, roots), or a slight laxative (Glauber salts) or 

 diuretic (saltpeter) may be added. Cleanliness and a free ven- 

 tilation of the stable, are also of value in obviating at once auto- 

 intoxication and the admission of poison through the lungs. In 

 the same way a free allowance of drinking water is beneficial as 

 favoring a general elimination from the various enuuictories, and 

 a dilution of the plethoric blood. 



These precautionary measures are especially important in the 

 case of horses which have passed through a first attack and which 

 are in consequence strongly predisposed to a second. Horses 

 fed liberally on highly nitrogenous food ( oats, beans, peas, cot- 

 ton-seed meal), will also require specially careful oversight when 

 at rest for a day or two only. 



Treatment. The first and perliaps the most important con- 

 sideration is absolute rest. If the subject is stopped instantly on 

 the appearance of the first symptoms, the disease may be often 

 aborted. It is better to avoid the exercise of walking to a .stable 

 until such time as the severity of the attack has somewhat mode- 

 rated and then to move the subject only in the slowest and quiet- 

 est possible way. If the patient is already down and unable to 

 ri.se, he may be carried to the nearest stable in an ambulance or 

 on a .stone-boat, and there helped to his feet and supported in 

 slings. Though he may be unable to continue in the standing 

 po.sition without the sling, yet if he can use his limbs at all for 

 support, and is prevented from lying down, the breathing will be 

 rendered .so much more free and quiet, that it may greatly lessen 

 the transfer of the poisonous elements into the general circulation
