Darwin Correspondence Project

To Louis Agassiz   1 March [1841]

12 Upper Gower St | London


I take the liberty of sending you a copy of my Journal, published some time since.— I have lately enjoyed the pleasure of reading your work on Glaciers,1 which has filled me with admiration. As I have briefly treated of the boulders of S. America in the accompanying volume I thought you possibly might like to posses a copy; and sending it you, is the only means I have of expressing the regret I feel at the manner in which I have alluded to (although probably the fact is unknown and quite indifferent to you) your most valuable labours on the action of Glaciers.2 I trust you will excuse the liberty I now take simply for my own satisfaction, and I beg to remain with feelings of much respect.

Sir | Your obedient servant | Charles Darwin

March 1st.—


L. Agassiz 1840.
CD had sharply criticised a number of Agassiz’s papers on glaciers in the Addenda to Journal of researches, pp. 617–18.


Has enjoyed reading LA’s book [Études sur les glaciers (1840)].

Hopes LA will pardon manner in which CD has alluded to his work on glaciers in his Journal of researches, of which he sends a copy.
