To Thomas Henry Huxley 17 July 
Down Farnborough Kent
My dear Sir
I beg to thank you for your very kind note of the 10th & your Report,1 which has interested me much, as I was ignorant & wished to learn about the metamorphoses of the Class in question.— I agree with your fundamental distinction between individuals & zooids,2 but I doubt whether it can be expected that creatures having so plainly the stamp of individuality as have many of your zooids will ever cease to be called individuals.
With many thanks | Pray believe me | Yours faithfully | Charles Darwin T. H. Huxley Esqe
Thanks for report [on echinoderms, Ann. & Mag. Nat. Hist. 2d ser. 8 (1851): 1–19]. Wanted to learn about metamorphosis of the class. Agrees with THH’s distinction between individuals and zooids, but thinks zooids will never cease to be called individuals.
