Dear Sir

I hope that you will not object to accept from me, as an old man & a lover of Science, a copy of M^r Wallace’s work, which I have despatched by post today.¹ M^r. W. has since published a work in 1 volume on the same subject, which he has made more popular & it is very interesting, but I do not think that it would be so useful to you.—²

I am glad that you have begun to work so energetically. You cannot expect to get any results, until several years have elapsed, & allow me to advise you to keep notes & go on accumulating facts, & then you will probably be able to publish hereafter a valuable essay.—

With respect to the plants which you have collected, I will communicate with Sir J. Hooker on the subject in the course of a few weeks, for at present he is much engaged.— I fear that the heights are hardly sufficient for any very high interest, but it may be otherwise—³

With all good wishes | Dear Sir | yours faithfully | Charles Darwin
