On the Replacement of Alcoholic Radicals. 37 
made at a somewhat lower temperature, and where only traces 
of benzoate of amyl were produced, that the benzoate of ethyl 
is decomposed by an alcohol with more difficulty than the acetic 
ethers. It will be remembered that this body is also less easily 
decomposed by water and alkaline bases than they; the reac- 
tion, however, takes place, and the extent of the decomposition 
effected is without doubt onl y a question of time and temperature. 
We next studied the action of an alcohol on the ether of a 
agree acid, a reaction which is capable, evidently, of giving 
e toa ereater number of products than those which were 
formed in the preceding cases; for, by the successive replace-
