    lead, mercury, tin ; in the second, those elements which are gases at the ordinary temperature, such as oxygen, hydrogen, &c., together with some solid elements, as sulphur, charcoal, &c. The number of the metals is much larger than that of the non-metals ; we are accpiainted with at least fifty-three metals, and with only fifteen non-metals. These sixty-eight elements constitute the material out of which the whole fabric of the science is built ; every description of matter which has been examined is made u]) of these elements, either combined together to form com])ounds or in the uncombined or free sttite. 'I'hc science of chemistry has for its aim the experi- mental examination of the properties of the elements and their compounds, and the investigation of the laws which regulate their combination one with another. The applica- tions of the principles of chemical science to the arts and manufactures are of the highest importance and interest ; they have exerted a most material influence upon the progress of civilisation, and have greatly tended to the elevation and benefit of mankind ; the instances are innumerable in which altogether new branches of industry ha\x- sprung up from the happy application of simple chemical principles, and there is scarceK* an article in common use in the productioir of which some application of chemistry has not proved of essential value. The following is a com[)lote list of the elementary bodies known at present (1891). The names printed in large capital italics, as BORON, arc the non-metals ; those in small roman capitals, as Aluminium, arc the more com- monly occurring metals ; those in small type, as Caesium arc the rarer metals. 2saj/u'^. • Alu.mimum • Antimony - A/OSEN/C Hariu.m Rerylliiini ttiSMurii JiORUN ■ BROJ\nNE C.ADMIL'.M 1 Fur :ui Symbols.
