Hydric selenide. 
Hydric telluride. (Telluretted hydrogen.) 
With regard to the combinations of hydrogen with nitrogen, phos- 
phorus aud, carbon, into which the ali enters in multiple pro- 
portions, they may be indicated by numbers as 
Monohydric phosphuret.(59) 
Bihydric phosphuret. Protophosphuretted hydrogen. 
Trihydric phosphuret. Perphosphuretted hydrogen. 
Hexahydric phosphuret.
