WORMS 



Drachm doses of tartar emetic (given every other night in 

 food) are useful for the destruction of tape worms. Perhaps 

 the best remedy of all is that of male fern, either as an emulsion 

 or in the form of liquid extract. 



THE GAD-FLY. 



The gad-fly usually attacks animals whilst they are 

 grazing, and commonly during June, July, August, September 

 and October. The fly is yellowish brown, and has black 

 markings. 



The hinder end of the female's body is provided with a 

 prolongation known as the ovipositor. The eggs are laid during 

 the months stated, and deposited upon the inner sides of the 

 knees, on the mane and shoulder, etc. They cause the horse 

 some discomforture, and it is quite possible that the animal 

 licks the parts ; in this way the immature parasite finds its 

 entrance into the horse's stomach. 



It takes from five to twenty-one days for the ova to develop 

 into the maggot stage. The larva attach themselves to the 

 upper portion of the lining membrane of the stomach, and in 

 this situation they remain for eight to ten months, subsequently 

 being expelled with the excrement. These are called " bots." 

 After their expulsion — all things being favourable — they 

 develop into the fully developed fly. This occupies about six 

 or eight weeks. 



Treatment. — {Prevejitive). — House when flies are likely to 

 be about. Give 2 ounces of turpentine and half a pint of 

 linseed oil once or twice a week. 



Externally. — Apply a dressing composed of i ounce of 

 creolin, 2 ounces of terebene, and i pint of linseed oil, mixed 

 together. Repeat if necessary.
