    DESCRIPTION OF THE PLATES. Plate I. Fig. 1. Represents an apparatus useful for many kinds of distillation. A the furnace, B a tubulated re- tort containing the materials to be distilled. D a glass balloon, supported by the stand E, to receive the first products of the distillation. C is an adopter for con- necting the retort with the receiver, so as to keep the latter at a sufficient distance from the heated materials. F a series of tubulated glass bottles, connected together by bent tubes, and forming what is usually called a Woulfe’s apparatus. Fig. 2. represents a common glass retort; an instru- ment much used in chemical laboratories for various purposes. Fig. 3. is a tubulated retort, that is, an instrument like the latter, with an orifice at the bend and with a ground stopper to fit it. This is the most useful kind of retort, as materials may be put in through the tubu- lure during an operation. Figs. 4. 5. and 6. are crucibles of various descriptions. They may be made of metal, of black-lead, or of any re- fractory argillaceous earth. Those made of baked and raw clay, and of the shape marked fig. 4. are usually called Hessian crucibles; fig. 5. is the common shape of the black-lead crucible; and fig. 6. is commonly called a melting-pot. Plate II. Fig. 7. is a glass-bell to be inverted over water and
