(From an Arabic word, athan). Among the chemists it is a sort of digesting furnace, contrived to maintain its heat a long time, communicating with its chimney by a lateral canal, as the furnace for a sand bath. It is carried to a considerable height above the part where this canal enters, filled with fuel to the top, and closely covered: as the lower part of the fuel consumes, it is supplied by what is above, which falls down into its place: thus a constant and equal heat is maintained a long time without any attendance. See Fornax.

(From to sustain, or to carry). The name of the first vertebra of the neck; so called because it sustains the head, as Atlas was supposed to sustain the earth. It is a bony ring, and in its back part it receives the processus dentatus of the second vertebra; it hath no spinal process; its transverse processes are very thick; instead of the two superior oblique processes, which the other vertebrae have, there are two oblong holes, which receive the condyles of the os occipitis, and the inferior oblique processes are horizontal to admit of rotation.
