cording to the circumstances and modes of preparation. In conclu- 
sion, the author states that when propylene gas is exposed to fuming 
muriatic acid it is slowly absorbed. The action takes place more read- 
ily ata higher temperature. The product is a neutral liquid insoluble in

It is clear that this tribasic alcohol must yield 3 species of ether, since 
if R represents the radical of an acid, 1, 2 or 3.eqs. of hydrogen in the 
above formula may be replaced by 1, 2 or 3 eqs. of R. Thus the three. 
species of stearine will have the formulas,

All these combinations, as well as a triacid nitrate, a biacid sulphate 
and a uniacid phosphate, have been obtained already. As the radical 
CeHs is tribasic and equivalent to 3 eqs. of hydrogen, we ought to ex-

tained by Berthelot and Luca. In conclusion, Wurtz points out tha 
there ought to exist 8 glyceric ammonias, in which 1, 2, or 3 eqs. of NH 
may be supposed to replace 1, 2, or 3 eqs. of Oz, just as ethylamine 
nso be considered as derived from alcohol by replacing Oz in CsHeOz

considered as water with a single double or treble equivalent, a certain 
number of equivalents of hydrogen being replaced by other radicals. 
We may consider glycerine with the formula CeHs0z+3HO, as hay-
