To Asa Gray 27 November 1876
Down, | Beckenham, Kent.
Nov 27. 76.
My dear Gray,
Many thanks for your pleasant letter, & for the correction of my stupid blunder.1 I hope that you will have received by this time a nearly complete set of sheets; but in case they should have failed, I send another set with the exception of the four or five last pages & title page which will come very soon.2 I shall be delighted to send you sheets in advance of the Orchid book, & have written for them today3
Only yesterday I discovered that I had overlooked one of your papers on Platanthera, from which I could have extracted two or three good facts, & this has vexed me. I find it very difficult to keep references distinct for various subjects.4
Ever yours very sincerely | Charles Darwin
Thanks for a correction. Hopes AG now has all the sheets of Cross and self-fertilisation.
