. Elements of chemistry ... 242. A matrass^ Fig. 37, is a glass vessel, inthe snape of an egg: with a long neck. It isemployed in effecting the solution of such sub-stances as require heat, and long-continued di-gestion, for that purpose. When used, they arecommonly placed in a sand bath, that is in sandmoderately heated. 243. A retort and receiverare represented at Fig. , «, are egg shapedvessels, with the neck tur- -ned on one side. These ves-sels are of various capaci-ties, from a gill to a barrel,or more. They are made of glass, metal, or earthen ware, but most commonly of glass.

In the process of distillation, in collecting the gases,in concentrating the acids, and in a great variety of otheroperations, this vessel is universally employed. The receiver, b, is a necessary appendage to the retort,and is destined to receive whatever comes over from it,during the process of distillation. For common purposes,these vessels are made of gla
