To J. T. Moggridge   12 June [1874]1

Down Beckenham

June 12th.

My dear Sir

It is very good of you to write me so interesting a letter, for I have so many to write that I never can make a fitting return. It has pleased me much to hear of M. Duval-Jouve, some of whose writings I have read, and had formed a high opinion of him, but did not know that he was an evolutionist. I suppose I shall receive, the Almond-Peach stones tomorrow or hereafter. I am delighted to hear of your great success with the trap-door spiders.2

Possibly I may have to tell you something about seeds being affected by very weak acids, to which I have been led by a very different course from the ants; but I do not know yet whether my experiments will not turn out to be complete failures.3

Pray believe me | Yours very sincerely | Ch. Darwin

Your drawings always make me bitterly envious.4 If I could draw such sketches I would have them framed and glazed.

The year is established by the relationship between this letter and the letter from J. T. Moggridge, 11 June 1874.

See letter from J. T. Moggridge, 11 June 1874, and especially nn. 1, 5 and 6. For a complete list of Joseph Duval-Jouve’s publications, see Flahault 1884, pp. 176–82; there are two papers by Duval-Jouve in the Darwin Library–CUL that predate this letter (Duval-Jouve 1865 and 1870).

Moggridge had carried out experiments to test the effect of formic acid on seeds in order to explain why seeds collected by ants did not germinate (letter from J. T. Moggridge, 7 March 1874, nn. 3 and 6). CD was investigating how the acid secretions of insectivorous plants were stimulated, and their role in the absorption of nutrients from organic matter (see letter to Asa Gray, 3 June [1874] and n. 8), but he also demonstrated that exposing seeds to the secretions of Drosera (sundew) inhibited germination (Insectivorous plants, pp. 127–8).
