My dear Dyer

I do not know whether you have returned, but when you do & when you have got through the first rush of business, will you kindly enquire whether you have seeds or plants of the enclosed 5 names.—²

Pfeffer says that they all move considerably their leaves at night, but I cannot make out from what he says whether the leaves rise so as to stand vertically or almost vertically, at night, in which case they would be said to sleep.³

I want to know about the distribution of sleepers in the general system. Perhaps you could get M^r Lynch to look at any of them which you may possess at night—⁴ I sh^d. however like seeds of any if you chance to have such seeds.—

I hope that you & M^rs. Dyer have returned or will return refreshed & invigorated by your tour.⁵

I have nothing to say about myself, except that we have almost finished the experimental part of our work, & must now begin modelling an enormous pile of notes into some sort of fashion, & this will be an awful job.⁶

Yours very sincerely | Ch. Darwin
