d’en confirmer la parfaite exactitude.” He ag in addi- 
iquid bromine and concentrated ee acid act similarly 
upon both sulphids. Potassic hydrate, moistened with alcohol, 
absorbs both very rapidly. inte is and a hydro- 
carbons dissolve them both with fi mmo however, 
either gaseous or in solution, is the best ane for dangling 
these two bodies from each other. While the vapor of carbonic 
disulphid reacts only very slowly upon liquid ammonia, carbonylic 
sulphid gas . abso ae d immedi ately. The vapor of €S, mixed 
With air, remain many hours in contact with ammonia gas,

with dry ammonia forms immediately a beautiful crystalline 
compound which is deposited a the walls of the cont ves-
