My dear H.

Your magnificent present of Aldrovanda has arrived quite safe.² I have enjoyed greatly a good look at the shut leaves, one of which I cut open. It is an aquatic Dionæa, which has acquired some structures identical with those of Utricularia!³

If the leaves open, & I can transfer them open under the microscope I will try some experiments, for mortal man cannot resist the tempation.— If I cannot transfer, I will do nothing, for otherwise it w^d require hundreds of leaves.—

You are a good man to give me such pleasure

Yours affect | C. Darwin

Pray thank Oliver very much for his paper; they seem marvellous little bladders & unlike those which I have examined.⁴
