To Ernst Haeckel 9 March 1864
Down. | Bromley. | Kent. S.E.
Mar 9. 1864
Dear & Respected Sir
You must permit me to thank you sincerely for the present of your paper1 & for the Stettin Newspaper.2 I am delighted that so distinguished a Naturalist should confirm & expound my views, and I can clearly see that you are one of the few who clearly understand Natural Selection.3
I feel sure that you do good service by boldly expressing how far you agree with me.
Many men in this country & elsewhere really go nearly or quite as far as I do on the modification of Species, but are afraid openly to express such views. I have been particularly struck & interested by your remarks on the individual variability of Sapphirina. This sentence will be remembered by me & quoted hereafter.4
With sincere respect I remain dear Sir | yours very faithfully | Charles Darwin
Thanks for paper ["Über die Entwicklungstheorie Darwins", Amtl. Ber. Versamml. Dtsch. Naturforsch. Aerzte 38 (1863): 17–30]. Delighted EH confirms his views. Many in England afraid to express views openly.
