To Albert Gaudry 17 September 1
Down. | Bromley. | Kent. S.E.
I received some time ago your kind present of your Considerations Génerales … de Pikermi; but I have delayed thanking you until I had time to read your work.2 I have now done so with the greatest possible interest. Your observations on many points, especially on the various intermediate fossil forms, seem to me most valuable;3 & I formerly read with great interest some of your memoirs in the Bull. Soc. Geolog. de France, especially that on fossil monkeys.4 I will venture to make one little criticism, namely that you do not fully understand what I mean by “the struggle for existence, or concurrence vitale;5 but this is of little importance as you do not at all accept my views on the means by which species have been modified.
With my sincere appreciation of the value of you paleontological discoveries, & with my thanks for your obliging present
I have the honour to remain | Dear Sir | yours faithfully & obliged | Charles Darwin
Thanks AG for Considérations générales [sur les animaux fossiles] de Pikermi . The observations on the various intermediate fossil forms seem most valuable.
AG does not fully understand what CD means by "the struggle for existence, or concurrence vitale".
