   sulphydric acid, or as a derivative of hydrogen sulphide in
   which one half of the hydrogen is replaced by a base (as
   potassium sulphydrate, {KSH}), or as a hydrate in which the
   oxygen has been wholly or partially replaced by sulphur.

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
