To George Rolleston 7 March 1
Down Bromley Kent
My dear Sir
Though you so kindly tell me not to write, you must let me have the pleasure of thanking you, busy as you are, for taking so much trouble to explain to me, the curious point of cyanosis & the clubbed nails.2 It may work in well, yet the case seems very complex.— I sincerely thank you.—
Yours very faithfully | 〈Charles Darwin〉3
How truly I agree with your remark on “borrowing organs” “prophetic types” &c &c!4
I hope you will work out the point about the mucus tubes; & I wish you could at same time work out the relation of the mucus tubes in Annelids with tracheæ of Insects. This has, always, seemed to me a curious case.5 | C. D.
Thanks for explanation of cyanosis and clubbed nails.
Hopes GR will work out point about mucus tubes.
