=Horse Bot Fly.=--Everyone is familiar with the common nit fly and the yellow nit that is attached to the hair on almost all parts of the horse, but especially on the chest and legs. The young larvæ or even the egg may be transferred from these regions of the body into the mouth by the horse biting these parts. The grub passes into the stomach where it attaches itself to the mucous lining and continues its development. The bot is not so dangerous as it is popularly supposed to be. They may, when attached in large numbers to the right side of the stomach, interfere with digestion and be responsible for some of the digestive disorders and colics. They are uniformly present in the stomach of all horses that are kept in the open where flies can get at them. A carefully groomed animal may be free from them. The eggs may be destroyed by rubbing the body with a rag wet with kerosene. One of the most common remedies for bots, and at the same time the most useless, is a mixture of molasses and milk. Bots are hard to dislodge from the stomach until they have completed their development there and pass out of their own accord. Half-ounce doses of turpentine three hours apart until three doses are given, followed by an ounce of powdered aloes as a physic, is a good remedy and easily administered. Mix the turpentine with half a pint of milk or gruel and give on an empty stomach. Carbon bisulphide is a good remedy. Take two drachms or one-fourth of an ounce of this and shake with a pint of cold water and drench. Repeat this every two hours until an ounce of bisulphide is given, then give a physic of aloes. These remedies should be given on an empty stomach. [Illustration: HORSE BOTS IN STOMACH The bot fly lays its eggs on the hair of the horse. These, taken into the stomach, hatch out and give rise to horse bots or young maggots that attach themselves to the walls of the stomach. After becoming grown they loosen themselves and pass out with the feces.]
