every four hours, whilst the symptom lasts. Build up the strength 

 of the mare hy the following: Sulphate of iron, three drachms; 

 gentian root, three drachms. Mix, and give in one dose every 

 day, for a week or ten days. Give good feeding. 



Caution. Unsafe to use ; will return again. 



Indigestion. — However much man, in the sedentary w^alks of 

 life, may be the subject of this disease, the horse with a task-mas- 

 ter is comparatively free from it. Cases do occur, occasionally, in 

 our large cities, where in too many cases the horse is left standing 

 in the stable twenty out of the twenty-four hours. Idleness be- 

 gets indigestion, and indigestion begets crib-biting, or wind-suck- 

 ing, and between them the poor horse loses flesh, condition and 

 spirit. (See Crib-biting.) 



Treatment. Send the horse to pasture, and when he returns give 

 him regular feed, and regular work to prevent a return of it. 



Infection. — (See Contagion.) 



Inflammation. — Inflammation of the various portions or parts 

 of the body will be found treated of under the name of the organ 

 or part aflected. 



Influenza. — This is a name which is properly applied to an 

 epizootic catarrh of frequent occurrence in the spring of the year. 

 Indeed, it is verv rare that we see a cold run its course as such, 

 without some complication of one kind or another. 



Sijmj^toms. A chill or shivering fit, succeeded by increased heat 

 of the body, with fever and irritation. Loss of appetite, cough, 

 discharge of miicus from the nose, watering of the eyes, great 

 prostration of strength, followed in a day or two with swellings of 

 the legs, and in bad cases, of the belly, breast, and in males, of 

 the sheath ; such is a true and succinct account of the s\'mptoms 

 of this disease. The symptoms will vary, as in other diseases, 

 with the intensity of the afi'ection. 



Causes. A subtle poison in the air, sudden changes in the dry- 

 ness or moisture of the earth's surface, easterly winds, cold accom- 

 panied with dampness in the air. These are conditions wdiich too 

 often accompany or precede influenza, which differs from an at- 

 tack of common cold, chiefl}^ in the severity of its eff*ect, causing 

 more fever and greater debility. In England it was first observed 

 in 1819, and again in 1832, and more or less ever since. In the
