Hydrosulphide \Hy`dro*sul"phide\, n. (Chem.)
   One of a series of compounds, derived from hydrogen sulphide
   by the replacement of half its hydrogen by a base or basic
   radical; as, potassium hydrosulphide, KSH. The
   hydrosulphides are analogous to the hydrates and include the
   mercaptans.

	Sulphydrate \Sul*phy"drate\, n. (Chem.)
   A compound, analogous to a hydrate, regarded as a salt of
   sulphydric acid, or as a derivative of hydrogen sulphide in
   which one half of the hydrogen is replaced by a base (as
