Hearty thanks for all your kindness.
Do not hurry over Asa Gray.

He strikes me as one of the best reasoners and writers I ever read.

He knows my book as well as I do myself.
LETTER 113.

TO C.LYELL.15, Marine Parade, Eastbourne, October 3rd [1860].
Your last letter has interested me much in many ways.
I enclose a letter of Wyman's which touches on brains.

Wyman is mistaken in supposing that I did not know that the Cave-rat was an American form; I made special enquiries.
