    diagram at page xxxviii, causing 1 atom of oxygen to be liberated from that substance, which uniting with the hydrogen of the muriatic acid, as in the former case, water is generated, and the chlorine of the muriatic acid escapes in the state of gas. By this method suU 'phate of soda and sulphate of manganese are left in the retort, but no muriate of manganese is formed, the whole of the muriatic acid being decomposed in the manner explained. The latter way of procuring chlo- rine, being cheaper than the former, is resorted to when chlorine is required on the large scale for the purposes of bleaching, &c. Chlorine is a greenish-coloured gas, whence its name it has a very disagreeable, peculiar smell, and astringent taste, is powerfully destructive of life, and produces a most suffocating effect even when inhaled in a state of very great dilution with atmospheric air. Like most other gases which prove fatal by inhalation, it acts by producing spasm as well as irritation of the glottis. It is considerably heavier than atmospheric air, its sp. gr. being about 2.5 : 100 cubic inches, ac- cording to Dr. Thomson, weigh 76.25 grains, at the standard temperature and barometrical pressure. Its atomic weight is estimated at 36. When submitted to a pressure equal to that of about 4 atmospheres, it becomes a limpid, bright yellow-coloured liquid; but on the pressure being removed, it again assumes its gaseous form. It unites with some bodies, giving rise ^ From gvee^i. /3
