Thanks for THH’s address [to Geological Society, Q. J. Geol. Soc. Lond. 25 (1869): 28–53]. Admires it and enjoyed attack on William Thomson hugely, but would tremble if he were in THH’s boots. Distinction made by THH between evolutionists and uniformitarians is too great. CD’s sentences on age of world in Origin will do, but he might have been less timid had he read THH.
