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.

CD responds to information about residue of milk digested by Drosera. Is obliged for information on strength of acids and albumen and now has little doubt acid had impaired the leaves. Awaits word on pepsin and papaw juice.

CD wants to see TLB before he leaves London. Much obliged for his aid.
