Excerpt from Lectures on the Elements of Chemistry, Delivered in the University of Edinburgh, Vol. 1 H represents a cucurbit, with its capital ll. Its form is very nearly that of the common still. To promote the couden sation, the capital should be of a considerable diameter. Observe that the outer rim of the capital should be lower than the hole h in the middle or throat; otherwise, the vapour which condenses on the roof, and trickles down its inside slope, would fall back again into the body H. But the rim being lower, the condensed fluid collects there, and from thence goes into the spoffig, and runs down into the receiver. The form of a capital is not unlike a mushroom. Observe also, that the throat of the capital should go into the neck of the body, and not encompass it. If the neck fits into the throat, the condensed fluid lies on the luting of the joint, and is contaminated by it.
