Sends sodium carbonate for Drosera experiments. Will try to determine what the solvent is.
Is going to Switzerland, so analysis of Drosera washings will be delayed. Agrees with CD that solvent is probably pepsin.
CD’s discovery of acidity of Drosera secretion is interesting. EF explains how hydrochloric acid can be detected and identified. [See Insectivorous plants, p. 88.]
Has sent CD some pure distilled water for his Drosera experiments.
The results of EF’s tests for acids in the secretion of Drosera are largely negative [see Insectivorous plants, p. 88].
Sends some litmus paper for CD.
