248. The author's views regarding the diastase-secreting activity of the aleurone- 

 layer of Grasses have met with opposition in various quarters. The principal objec- 

 tions have already been discussed in the third [German] edition of this work (Note

 ment with N. J. C. Muller and Hanstein, but in opposition to De Bary) that secretions
