Gal prepared also ethylic butyro-glycollate, i Soka by treating 
Potassic butyrate with ethylic monobromacetate; ethylic butyro-butyl- 
lactate (better butyro-oxybutyrate), { ple and ethylic aceto-oxy-

aan The last is isomeric with butyro-glycollic ether, 
— containing €,H,,@,. The number of mixed acids which can 
a be formed is, as Gal observes, very great; especially when not only
