BOTS. The larvæ of the gad-fly. The eggs are deposited by the female fly on the horse’s shoulder and on parts of the body within reach of the tongue, by which they are carried to the mouth and find their way to the stomach. They usually resist all attempts to expel them. The most promising treatment consists in rubbing down in hot water about 2 or 3 drms. each of aloes and assafœtida; and when the solution has cooled, adding to it 1 oz. each of turpentine and ether. Repeat this dose two or three times a week, omitting the aloes if necessary.

BOUGIE (bōō′-zhē). [Fr.] Syn. Ce′reus, Cere′olus,[227] Cande′la probato′′ria*, L. In surgery, a long slender instrument, originally of wax,[228] introduced into the urethra, œsophagus, or rectum, in stricture and other diseases of those organs.

[227] Properly, a ‘little bougie.’

[228] Hence the name.

Prep. 1. (Prof. Pickel’s.) Amber (melted), 1 part; boiled oil, 3 parts; mix, cool a little, and further add of oil of turpentine, 1 part; spread the mixture, at 3 successive intervals, upon loose spun-silk cord or web; dry in a heat of 150° Fahr., and repeat the process until the instrument has acquired the proper size; lastly, polish it, first with pumice-stone, and afterwards with tripoli and oil. This is the original receipt of the once celebrated French professor Pickel, and is still generally used, slightly modified, on the Continent. At the present time, in Paris, a little caoutchouc, equal to about 120th of the weight of the oil employed, is generally added. For the best ELAS′TIC BOUGIES the process usually occupies from 6 to 8 weeks, to allow full time for the drying and hardening of the composition. When the bougie is required to be hollow, a piece of polished metallic wire is introduced into the axis of the silk; or tin-foil is rolled round the wire and the composition applied as before. When dry and hard the wire is withdrawn.

2. (Hunter’s.) Yellow wax, 2 parts; red lead, 3 parts; olive oil, 6 parts; slowly boiled together until combination takes place; strips of soft linen (rather wider at the one end than the other) are then dipped into the composition, rolled up firmly, and finished off on a polished slab.

3. (Piderit’s.) Olive oil, 1 part; wax, 6 parts; as before.

4. (Bell’s.) Lead-plaster, 11 parts; yellow wax, 4 parts; olive oil, 1 part.
