From W. H. Dallinger 10 January 1876
Summary
Has confirmed CD’s observations on Drosera.
Asks whether CD agrees that it is "no longer a fact" that the bladders of Utricularia vulgaris enable the plant to become lighter for fecundation and heavier when that act is accomplished. Plans to undertake further observations, under very high-powered microscopes, of mechanism of digestion.

The results of WHD’s long series of investigations of effects of steadily and slowly altered environment on putrefactive organisms "palpably demonstrate [CD’s] great doctrine".
