To Edward Frankland 16 July [1873]
Summary
Thanks EF for his offer of assistance. Could the viscid secretions [in glands of Drosera] contain pepsin? Will the sodium carbonate render the testing of organic matter difficult? [See 8979.] Will send the fluid in a fortnight.

To Edward Frankland 21 September [1873]
Summary
Although CD’s experiments with pepsin were unsuccessful, he observed that the glands [of Drosera] as far as acid is concerned act just as the stomach of a mammal. Further experiments detailed. The secretion must contain something analogous to pepsin. [See 9062.]
