Dr. J. Gruess has adapted the reaction between diastase, guaiacum, 
and hydrogen peroxide to the microchemical recognition of diastase. 
The alcohol is then allowed to evaporate and the object brought into 
a more or less dilute solution of H,O,, which colors the precipitated 
diastase of the cells a beautitul blue. By the use of this test, con- 
trolled by others, Griiss claims to have established the theory of Hab- 
erlandt which ascribes the secretion of diastase to the aleurone layer 
of grass seeds. He also finds that diastase is produced by the endo- 
sperm and cotyledonary tissues, and refutes the statements of Brown 
and Morris. (Cf. Ber. d. deutsch bot. Gesells. 13: 1. 1895.)
