My dear Hooker
I was very much pleased to get your last letter, received about a fortnight ago; I cannot remember its date & it is locked up with your others at Down; I am writing this at Malvern, whither I have come for a week of extra aqueous treatment. You thank me for my letters,—you apologise for not having written oftener to me, & in doing both, you stab me & remind me how neglectful I have been about letters; but my case is too bad for apologies, so I will say no more.—
Your verses on stratification are capital, & I feel their truth even more than
when I wrote my S. America (N.B that you
By the way you sometimes speak of other people having philosophical minds, as if you had nothing of the sort; now this is one of the greatest falsehoods ever told by implication,—read your own Galapagos paper & be ashamed of yourself— compare any half-dozen-pages of the Antarctic Flora with other systematic works, dull as they generally are, & you will never have the face to depreciate yourself again.—
With regard to myself I have not been quite so well for some months past,—though the sickness has not come on, & my life altogether is bliss compared to what it was formerly: I find I do not improve in strength to withstand excitement; but my Water Doctor continues to give me hopes & I am got absolutely to like my aquatic life except the dressing & undressing. Everyone tells me that I look quite blooming & beautiful;—& most think I am shamming, but you have never been one of those.
At last I am going to press with a small, poor first fruit of my confounded cirripedia, viz the fossil pedunculated cirripedia. You ask what effect studying species has had on my variation theories; I do not think much; I have felt some difficulties more; on the other hand I have been struck (& probably unfairly from the class) with the variability of every part in some slight degree of every species: when the same organ is rigorously compared in many individuals I always find some slight variability, & consequently that the diagnosis of species from minute differences is always dangerous. I had thought the same parts, of the same species more resembled than they do anyhow in Cirripedia, objects cast in the same mould. Systematic work wd be easy were it not for this confounded variation, which, however, is pleasant to me as a speculatist though odious to me as a systematist.— Your remarks on the distinctness (so unpleasant to me) of the Himmalaya rubi willows &c compared with those of N. America &c are very interesting; if my rude species=sketch had any small share in leading you to these observations, it has already done good & ample service, & may lay its bones in the earth in peace.—
I never heard anything so strange as Falconer's neglect of your letters: I am
extremely glad you are cordial with him again, though it must have cost you an effort.
Falconer is a man one must love— pray give him my kindest
Your affectionate friend | C. Darwin

- f5 1339.f5The first volume of Fossil Cirripedia was not published until early in 1851. CD's ‘Journal’ for 1851 states, ‘early part [of year] finished fossil Lepadidae’ (Correspondence vol. 4, Appendix I). The correspondence of the rest of 1850 indicates that the delay was due partly to the arrival of more specimens from Japetus Steenstrup but mainly to James de Carle Sowerby's slow progress in engraving the plates. In 1851 there were further delays in production and distribution of the volume.
