horses out to pasture in the summer months, and are produced 

 from the eggs laid or glued to the fore legs of the horse by the hot fly. 



Symptoms. An unthrifty coat, and loss of flesh after a 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 de- 

 bilitating effects of the bots' presence may not interfere 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 para- 

 sites short of killing the horse also. Once the eggs are in the 

 stomach, which seems to be the natural nursery both for their pro- 

 tection 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 vnngs, and 

 fly about, commencing the propagation 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. Injection of linseed oil, or tobacco smoke. 



(3.) Strongylus. — This variety, and a species of Filaria, are 

 sometimes found in the blood vessels, and are similar in effects 

 produced in the horse, to those seen in sheep affected with rot. 



Cause. Feeding on wet and marshy land, and pasture having 

 been flooded with water. Who has not heard of the effects pro- 

 duced from this cause, in animals grazed upon the course of the 

 river Nile, in Egypt, after each inundation?
