On his recent talk at the Anatomical Department in Philadelphia. On drosophila wing experiments. On Martha's improving health condition.
Review of F. O. Schmitt's chapter in "Analysis of Development". "He has not a single word for all my efforts trying to relate the lipo-protein structure of the cell membrane (of which he speaks a lot) to the biological phenomena of cellular adhesion, locomotion, cell division, differentiation. Instead he glorifies the blah-blah of Weiss."
