sulphosinapicacid

Chem . C3H5CNSH2S. Known only in combination with a base. Its salts are formed by the direct union of allylic sulphocyanate with a metallic sulphydrate, as in the case of the pota ium compound (C3H5) CNSKHS, which is obtained in large transparent rhombic crystals, readily decomposing on exposure to the air.

The solid, SO2, melts at-79°, and the liquid oxide boils at-10. Its specific gravity=1:45, and it is irrespirable and incombustible. Sulphuric oxide is obtained by the oxidation of sulphurous anhydride, and crystallizes in beautiful white slender needles. In the liquid state it forms a liquid thinner than oil of vitriol. It boils at 35°, and has a specific gravity of 1.97. sulphur-rain, subst . Pollen from the Pinacese, Amentaceæ, ., which has been floating in the atmosphere, and is brought to the ground by rain. sulphur-salts, s . pl . Chem.: Compounds of sulphur acids and sulphur bases, e . g . , sulph arsenate of pota ium, 3K2S ASS5 =2K3ASS. sulphur-springs, s. pl. Phys. Geog.: Hot springs in which sulphur is mixed with the water. They usually occur in volcanic districts of intermittent activity. The sulphur springs of Rotomahana, New Zealand, were de stroyed by an eruption in June, 1886.
