There are two sorts of cucurbitals: the one of copper, the other of horn. That of copper is open at the one end, and close at the other; that of horn is likewise open at one end, and at the other has a small hole. Into the copper one burning linen is put, and its mouth is clapt close to the body, and is prest down, till it adhere to it. The horn kind is only applied to the body, and after that, when a person has sucked out the air by the small hole, and that is closed with wax, it sticks, as well as the other. Both of these are made not only of these two materials, but of any thing else. Where no better can be got, a small cup with a narrow mouth is fit enough for the purpose. When it adheres, if the skin has been cut before with a scalpel, it will bring out blood: if the skin is whole, air. Wherefore when the offence is from matter contained within, the first method is to be pursued: when it is only a flatulency, the other is commonly used.
