Abstract
DURING a study of the amino-acids of the hæmolymph of insects, a substance was isolated from the blood of Melolontha vulgaris which turned out to be asparagine. This finding may be of interest because, to my knowledge, this substance has not been met with in animal fluids or tissues before, while it is a characteristic constituent of many plants.
