The Bot Fly.
A correspondent of a northern paper gives the following interesting particulars in regard to the bot fly : —The stomach seems to be the natural nursery for the protection and the propagation of the stomach bot. When the eggs have remained in the stomach for a year they become a perfect chrysalis (that is, the form of a butterfly before it reaches the winged state), and then they release their hold of the stomach ani are expelled with the dung. It will be provided with wings in a short time, and fly about commencing the propagation of its species which passes through the same period of incubation.
They are of two kinds, stomach and fundamental bots. The stomach bots are the result of turning horses into pasture in the summer months, and are produced from the eggs, laid on the forelegs of the horse by the bot 11 v.
Symptoms arc rn unthrifty coat, and loss of flesh after running out to pasture. All horses which ran out to grass are sure to have hots in their stomachs. JTo medicine can be given which will affect the hot. and will not destrov tho coating of tho stoma hi, am! injure or kill the horse, bo veterinary surgeon can distinguish tho symptoms of bo's from those of colic. In fact, thorn is but littlo doubt that 99 out of every 100 cases of belly ache arc no more nor less than colic and nor bots. Treatment. Too general condition of the horse should be impiMved so that the debilitating ciiV-ss of bots may not interfere with the general health of tho horse, xt us generally considered impossible to i expel or destroy the bots. Give the
following tonic medicines to improve the general condition i —Pulv. gen-tian"-jib, pulv. copperas -£lb, pulv. fenugreek -£lb, pulv. elecampane -£]b. Mix well and give a large tablespoonful once a day. The fundamental bot, like the stomach bot, is also the result of running out to grass. Instead of the eggs being deposited on the legs they are deposited on the lips of the horse. They are found in the rectum, and often seen about the anus and under the tail.
Treatment.—lnjections of raw linseed oil, or of tobacco solution.
