DISEASES OF THE HORSE 21 



having selected its place of residence, attaches itself to 

 the membranes lining the stomach and intestines, and 

 derives its sustenance during its stay from the wound 

 made by its hooks. In the summer the larva, after 

 living inside the horse for about ten months, quits its 

 hold and is expelled with the feces. Having concealed 

 itself near the surface of the ground it becomes changed 

 into a chrysalis from which the gadfly issues after an 

 inactive existence of from thirty to forty days. The 

 female fly becomes impregnated, lays her eggs on those 

 parts of the horse from which they can be most easily 

 licked off, and thus completes her cycle of existence. 



Symptoms : Membranes about the eyes and mouth are 

 very pale, as though the animal had lost a large quantity 

 of blood; they will also be subject to colicky attacks, hair 

 faded, dull, rough appearance, appetite poor and mani- 

 fests a pot belly. 



Prevention : The best means of prevention are spray-

 Carbolic Acid, 10%; Oil of Tar, 25%; Crude Oil, 65%. 

 Mix thoroughly. This prevents the gadfly from depos- 

 iting her eggs on the animals. 



Treatment : Withhold all food for twenty-four hours, 

 then administer Oil of Turpentine, one ounce; place in 

 a gelatin capsule and give with capsule gun. Follow 

 this in six hours with a physic consisting of Aloin, two 

 drams ; Ginger, two drams. Place in a gelatin capsule 

 and give with capsule gun. Repeat the above treatment 

 in a week or ten days to insure the expulsion of Bots 

 that might have escaped the first treatment. 



BRONCHITIS 

 Cause: It may be the result of debility, constitu- 

 tional diseases, inhalation of impure air, smoke, or 

 gases. Sometimes brought on by drenching by the 

 escape of liquid into the windpipe; remember, a horse 

 cannot breathe through his mouth. It may also be
