ing the same relation to alcohol with the formula CaHsO+-HO which 
SbOs-+ 3HO bears to +HO. e 3 stearines above mentioned 
will “os on this view the formulas CoeHsO3+Cs6H350s, 2HO, 
Colls03-+2Cs6H250s, HO. CoHsOs+48Cs6Hs5O0s ; while the gly- 
cerine ether of Berthelot and Luca will be CeHsOs-+CeHsQs, or 
more simply CeHsQs, bearing the same relation to CsHsO which 
SbOs bears to ZnO. We ought to expect by the action of dehydra- 
ting agents upon glycerine to obtain the body CeH4Q2, since CeHsOs, 
=CeH40O2z, and in like manner we should have the reac- 
tions CeHs03, 3HO—5HO=CeHsO, and CeHsO2, 3HO-6HO= 
eH2. Moreover we should have the acids CsoHeOs, and CeHsQOi0, 
produced by successive substitutions of Oz for Hz just as acetic acid 
is produced from alcohol by a similar substitution.—w. G 
On some new bodies sage to the Propionyl Series,—Zin1n 
has communicated the results of an investigation of the compounds of 
Propionyl which possess mie interest and importance. It will be re- 
» membered that propiony! is the radical of propionic acid and is homol- 
ogous with acetyl, its formula being CeHs. By the action of the iodid 
of this radical upon the salts of silver, Zinin has succeeded in prepar- 
ing an entirely new class of ethers of which the acetate, benzoate and 
carbonate are described. Acetate of Spe seis CeHs0+4C4H 20s (not 
to be confounded with acetate of propyl, CeH70+CsHsOs) isa color- 
less liquid, lighter than and but pee eel in water, but soluble ia 
all proportions in alcohol and ether. 1t has a neutral reaction, a sharp 
odor like that of acetate of ethyl, anda ans akesan! taste : it boils at 
acing the ibies and eyes. ‘The author does not give the constitution 
of this body, but it is doubtless the propionic aldehyde, the Teaction in

The io d of propionyl readily attacks mercury—much more easily 
than the vodide of methyl and ethyl. The product is the iodid of a new 
radical and has the formula CeHsHgel; it is therefore analogous to 
ethyl-mercury, methyl-mercury, &c. By double decomposition with 
the salts of silver it gives well defined crystalline salts, Hence the 
analogy between propiony! and ethyl is clearly established.—Bull. de

the interesting discovery that the volatile oil of mustard is the sulpho- 
eyanid of propionyl, and that it may easily be formed artificially ed 
distilling an alcoholic solution of sulpho-cyanid of potassium with 
thelot’s iodid of propionyl. (Am. Journal Sci., xix, 270). The oily 
fluid which separates from the distillate on the addition of water when
