Darwin Correspondence Project

To J. D. Hooker   [4 June 1866]

My dear Hooker.—

Many thanks for Asa Gray, as I always like to read him.1 I was very uncomfortable for two days & all the world looked dismal to me, but everything looks brighter again now.—2 I knew that you would not care a bit about my omission,3 but I was much vexed at my own stupidity & strange forgetfulness; it seemed to me on that day like softening of the Brain! & I could have improved my own work by considering all your excellent remarks.4 Well it is too late— Cordial thanks & farewell— Ask Oliver to do a little favour for me.5

C. Darwin


Hooker evidently enclosed a letter from Asa Gray with his letter of [2 June 1866]. There is a letter from Gray to Hooker, dated 10 May 1866, in the archives of the Royal Botanic Gardens, Kew (Asa Gray letters, ff. 411–12).
CD had complained of poor health and stomach troubles (see letters to J. D. Hooker, 31 May [1866] and [31 May 1866]).
See letter to J. D. Hooker, [2 June 1866] and n. 3.
Hooker had supported CD’s transmutation theory in his essay on Arctic flora (J. D. Hooker 1860a).
The favour was probably detailed in an enclosure. The enclosure has not been found; see, however, the letter from Daniel Oliver, 9 June 1866.


Thanks for Asa Gray’s letter, enclosed.

Knew JDH would not care about omissions but was vexed at his own forgetfulness.
