From G. H. Darwin 28 January 1878
Summary
Has been reading Samuel Haughton on geological time ["Notes on physical geology, no. III", Proc. R. Soc. Lond. 26 (1877): 534–46]. It is utter rubbish. Asks whether CD thinks GHD should write a critical note on the subject [see Nature 17 (1878): 509–10].

CD at first thought GHD should not answer Haughton [see 10689], but Hooker thinks if no correction is made Haughton’s error will be quoted for 20 years. CD is now inclined to agree.
