Sir C.
Lyell and Dr.Hooker, who both knew of my work--the latter having read my sketch of 1844--honoured me by thinking it advisable to publish, with Mr.Wallace's excellent memoir, some brief extracts from my manuscripts." LETTER 72.

TO J.D.HOOKER.

Down, May 3rd, 1859.
With respect to reversion, I have been raking up vague recollections of vague facts; and the impression on my mind is rather more in favour of reversion than it was when you were here.
In my abstract (72/1.

"The Origin of Species.") I give only a paragraph on the general case of reversion, though I enter in detail on some cases of reversion of a special character.

I have not as yet put all my facts on this subject in mass, so can come to no definite conclusion.
