though glycine is a stronger acid than base;' with ethyl butyrate the difference in the two solutions is the same in sense but not so great. Summary. Glycine, glutamic acid and aspartic acid exert a varying lipolytic action on methyl, ethyl, glyceryl tri-and phenylacetates, ethyl butyrate, and ethyl and phenyl benzoates. If these be arranged in the order of decreasing amounts of hydrolysis, the order will be different in the three cases where the action is caused by water, by glycine, and by

The effect of sodium chloride, sodium sulfate, and magnesium sulfate in solutions from 0.2 to 2 normal is not marked or consistent enough to be important for this work. The hydrolytic action of solutions of glycine and acetic acid on methyl acetate and ethyl butyrate is less than that of corresponding solutions of acetic acid alone; this difference is proportionately much less with ethyl butyrate. This indicates selective action.
