Dear Madam,

I am obliged for your kind letter, & it pleases me to hear that any of my works have interested you.¹ I am glad to hear of M^r. Henderson’s intended experiment. A similar one begun by me on Drosera failed owing to an accident.² Will you be so good as to tell M^r. Henderson that several considerations make me suspect that the good derived from an animal diet will be shown only by the production of a larger number of seeds & by the more luxuriant growth of the plants on the ensuing year.

I believe to remain | Dear Madam, | Yours faithfully | Ch. Darwin

P.S. I sh^d. much like to hear the results of M^r. H’s experiments.
