Summary

Is delighted to hear that Pinguicula and Drosera digest fibrin. Suggests diluting gluten in weak hydrochloric acid to remove starch. Enamel was nearly digested [by Drosera] overnight. Would like to try separating the digestive ferment of Pinguicula.

Summary

CD has helped leading physiologists to prepare a draft bill for legislation with regard to vivisection, and he hopes Lord Derby will support the bill and mention it to ministers of the Cabinet. Has heard that other groups are preparing bills for the same purpose, and feels it important that the science of physiology be protected as well as animals.
