Offers to experiment on the digestibility of chondrin and chlorophyll by Dionaea for CD.
Has noticed that painters depicting complex expressions give different expressions to the two sides of the face.
Is interested in comparative nutritive values of chondrin and gelatin. The former seems to excite Drosera more, though albumen does so to a higher degree than either. Also asks if chlorophyll is digested by animals; Drosera digests it hardly at all.
