To Ernst Haeckel   1 February 1866

Down Bromley Kent

Feb 1. 1866

My dear Sir

I write merely to say that I received safely this morning the photographs.1

I thank you cordially for all the trouble you have taken. I value them much & all the more as I did not know that some of these distinguished men had ever taken any part in the discussion on the modification of species.2

Believe me my dear Sir | yours truly obliged | Ch. Darwin
