THE LIFE AND LETTERS OF CHARLES DARWIN

My dear Darwin,

I have just finished your volume and right glad I am that I did my

best with Hooker to persuade you to publish it without waiting for a

time which probably could never have arrived, though you lived till

the age of a hundred, when you had prepared all your facts on

which you ground so many grand generalizations.

It is a splendid case of close reasoning, and long substantial

argument throughout so many pages; the condensation immense,

too great perhaps for the uninitiated, but an effective and important

preliminary statement, which will admit, even before your detailed

proofs appear, of some occasional useful exemplification, such as

your pigeons and cirripedes, of which you make such excellent use.
