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.

From J. S. Burdon Sanderson 25 April 1874
Summary
Purpose of experiments was to determine digestive activity of liquids containing pepsin. Gives required amounts of hydrochloric, propionic, butyric and valerianic acids. Describes experiment and gives results. Also experimented on digestive activity of butyric acid at greater temperatures than the termperature of the body.

From J. D. Hooker 17 August 1874
Summary
Describes his work on Nepenthes.
Cephalotus is a beast.
His address is a history of Dionaea, Sarracenia, and Drosera.
Thiselton-Dyer has helped enormously except with the observations; but his health is so poor that JDH thinks he is "evidently cut out for a Literate not a working botanist".

From J. D. Hooker 22 July 1874
Summary
Stupefied by CD’s trouble and kindness. All he wanted for Belfast meeting was assurance that mention of published work on Drosera, etc., in Nature, etc., would not interfere with CD’s book.
Would like his Nepenthes results to go to CD or to Royal Society, but prefers CD take them.
Cephalotus very puzzling.
Peas and cabbage grow twice as fast after two days’ immersion in Nepenthes as when placed in distilled water, but four days’ immersion seems to kill them.
Has a splendid Australian Drosera twice as big as D. rotundifolia.
