To G. R. Gray [20 November – 11 December 1840]
12 Upper Gower St
My dear Sir
I have been obliged to defer from the state of my health, until to day, the pleasure of thanking you for your very obliging present of your volume of the Genera of Birds.1 It is a work, which cannot fail, I should think, of being very useful to ornithologists & indeed to describers in other branches of Natural History.
I trust now you have completed this work, you will oblige me by kindly finishing the remaining M.S. for the Birds of Beagles Voyage.— I had hoped before this to have finished that part, but I have of late been so frequently unwell that all my plans have disarranged.2
I shall esteem it a great favour should you be able to finish at once Gould’s M.S.3 & Believe me, | My dear Sir | with many thanks | Yours very truly | Chas. Darwin
Thanks GRG for his gift [A list of the genera of birds (1840)] and trusts that now GRG will be able to finish John Gould’s MS for Zoology.
