Thanks for work on Lacerta muralis coerulea [Zoologische Studien auf Capri 2 (1874)].

On colour changes in rabbits. Suspects JBI’s is of impure origin.

Is correcting proof of Insectivorous plants.

Thanks DN for references.

The Apocyanaceae that catch Lepidoptera represent the most gratuitous case of cruelty in nature known to CD, since the captured butterfly is of no use to the plant.

Much obliged for GHK and MHC’s General glaciation [of Iar-Connaught (1872)].

Thanks for copy of translation of Variation

and the "admirable work on the microscopical structure of rock" [C. G. Ehrenberg, Mikrogeologische Studien (1873)].

Returns a Drosera, from which he cut a piece for microscopic examination.

Utricularia montana just arrived.

CD has never before seen the Utricularia DN has sent. Hooker had told him about it. Asks that her gardener observe young Utricularia: CD is interested in internal structure of little balls on bladders.

Sends photograph.

Stupidly missed Utricularia bladders, which he assumed were with the leaves. Has now found true bladders on roots and has evidence of captive prey. Thinks bladders capture subterranean insects. Thinks the large bladder-like structures are water reservoirs. DN’s plant has given him a most enjoyable day of work.

Received Darlingtonia; cannot explain its fructification.

Declines invitation.

Is happy to send his autograph.
