To Nicolai Krohn   18 December 18811

[4 Bryanston Street, London.]

[…] The number of worms in your garden is astonishing […] it will be an interesting observation, how soon the land is again stocked with worms, & whether the grass grows better before this happens.—2 I neglected to observe whether worms distruct[?] the roots of grasses.— You will probably be able to borrow […] my book ‘On the Formation of Vegetable Mould’ […] in which […] you will find a good deal about the natural history of worms3 […]

Footnotes

The date is provided by the sale catalogue; according the catalogue, the letter was addressed from Down.
See letter from Nicolai Krohn, 16 December 1881 and n. 1. Krohn had watered his lawn with a solution of perchloride of mercury, and observed a large number of dying earthworms emerge from underground.
Krohn mistakenly thought that CD had written an article in The Times on earthworms and had asked CD for a reference (see letter from Nicolai Krohn, 16 December 1881 and n. 2). Earthworms was published on 10 October 1881 (Freeman 1977).
