run at grass, may be taken as an indication that bots are 

 present within the stomach. 



Treatment. Improve the condition of the horse, so that 

 the debilitating eifects of the bots' presence may not inter- 

 fere with the general health and condition of the horse; 

 for it must be borne In mind that no medicine can, or will, 

 dislodge or destroy these parasites short of killing the 

 horse, also. Once the eggs are in the stomach, which 

 seems to be the natural nursery both for their protection, 

 and the propagation of their species, they cannot be re- 

 moved by force. In one year from the time the eggs are 

 taken Into the stomach, will the bot be a perfect chrysalis, 

 and will fall from the coats of the stomach, and be expelled 

 with the excreta or dung. In a short time after, it will be 

 provided with icings^ and fly about, commencing the prop- 

 agation of its species, which must pass through the same 

 period of probation or incubation, as its progenitors. 

 Give iron and gentian, in addition to good feeding, to 

 prevent the bots from debilitating the animal too much. 

 Take powdered sulphate of Iron and gentian root, each 

 three drachms; mix, and make one dose, to be repeated 

 twice a week. 



(2.) Fundament Bot. — Like that of the stomach, but 

 also the result of a run to the grass. Instead of the eggs 

 being deposited upon the legs, they are stuck to the muzzle 

 or lips of the horse, and are the color of the skin, hence 

 not often seen. 



Symptoms. The following year, during the summer 

 months, the larva of this species will be seen sticking 

 about the anus, and under the tail, which In spirited horses 

 prove a source of great uneasiness and Irritation. 



Treatment. Injections of linseed oil, or tobacco smoke.
