To W. C. Williamson   18 August [1880]1

Cambridge

Aug. 18th

From Mr. C. Darwin,

Your specimens, which have been forwarded to me here; are interesting; but I think the slowness of the change might have been expected under the circumstances, as in the case of tadpoles.—2

C. D.

The year is established by the relationship between this letter and the letter from W. C. Williamson, 10 August 1880.
Williamson had sent seedlings of Drosera capensis (Cape sundew), whose habit of growth when several plants were grown in close proximity resembled that of D. rotundifolia, the common or round-leaved sundew, and D. intermedia, the spoonleaf sundew. See letter from W. C. Williamson, 10 August 1880 and nn. 2 and 3. CD alludes to the fact that tadpoles will not develop into frogs in overcrowded conditions.
