Dear Sir,

Having just returned from a journey I find your very kind letter, which I hasten to answer at once.¹ I am highly pleased at the consenting remarks upon my: “Geschichte der Bestäubungstheorie,” especially as they are made by you who are the most competent judge, in our particular sphere of science.² I had made it my task in that essay to point out the merits both of some dead and living botanists from a point of view as objective as possible, and your kind consent is the more satisfactory to me as my critical examination and the results of it differ from the opinions of most of our reasoners. I am very much obliged to you for your great kindness and beg to say, that whenever in time to come I shall produce any new scientific work of this kind, it will be my endeavour to follow your trace, though I know that I shall hardly be able to bring forth anything like you. I shall soon forward to you an ample essay on: “Die Nectarien der Blüthen. Anatomisch-physiologische Untersuchungen”, in which relying upon your theory of natural selection I shall try to illustrate the anatomical structure of the nectaries.³ I hope you will agree with me in this point too.

I remain Dear Sir | Your respectfull and | obliged | W. Behrens.
