ture of glycerine and acetic acid with gaseous hydrochloric acid. 
The chief product of the action is bihydrochloric glycerine, 
which may be separated by fractional distillation; or, by heat- 
ing the crude product with caustic potash, hydrochloric glycide 
is directly obtained. It isa colourless liquid, heavier than water, 
and smelling like chloroform. It boils at 118°—119°: it is 
metameric with Geuther’s hydrochlorate of acroleine, with 
Riche’s monochlorinated acetone, and with chloride of pro- 
pionyle. 
Monohydrochlorie glycide combines directly with fuming hy- 
drochloric acid to form dihydrochloric glycide, C° H4 Cl? : this body 
may also be formed by acting on hydrochloric glycide with pen- 
tachloride of phosphorus, an action which gives rise to the forma- 
tion of trihydrochloric glycerine, 
C® H® ClO?+ PCI’ = C® H® Cl + PCI 0?;

and this, decomposed by potash, loses hydrochloric acid, and the 
new body is formed, 
C° H® C8—HCl=Cé H4 Cl?, 
This body is identical with what Berthelot has called epibrom- 
hydrine. It is metameric with bichlorinated propylene, and 
with Geuther’s chloride of acroleine. Similar compounds con- 
taining bromine and iodine were also obtained. 
By the action of ammonia on bihydrochloric glycide a base is 
formed, which the author considers identical with that obtained 
by the action of amznonia on terbromide of allyle. 
Hydrochloric glycide unites directly with the oxyacids to form 
a glyceric ether, contaiming an equivalent of oxyacid and of hy- 
dracid. Thus,—

By the action of water, hydrochloric glycide fixes two equi- 
valents, and monohydrochloric glycerine is formed :—
