Profoundly grateful for AG's article in Nature; he is especially pleased by what AG says about teleology.

My dear Gray
I have now read your article in Nature, & the 2 last paragraphs were not included in the slip sent before. I wrote yesterday & cannot remember exactly what I said, & now cannot be easy without again telling you how profoundly I have been gratified. Everyone, I suppose occasionally thinks that he has worked in vain, & when one of these fits overtakes me, I will think of your article, & if that does not expel the evil spirit, I shall know that I am at the time a little bit insane, as we all are occasionally.
What you say about teleology pleases me especially, & I do not think anyone else has ever noticed the point. I have always said you were the man to hit the nail on the head.
Yours gratefully & affectionately | Ch. Darwin
