HOOKER.
(19/1.

Sir J.D.

Hooker's letters to Mr.Darwin seem to fix the date as 1845, while the reference to Forbes' paper indicates 1846.) Down [1845-1846].
I am particularly obliged for your facts about solitary islands having several species of peculiar genera; it knocks on the head some analogies of mine; the point stupidly never occurred to me to ask about.

I am amused at your anathemas against variation and co.; whatever you may be pleased to say, you will never be content with simple species, "as they are." I defy you to steel your mind to technicalities, like so many of our brother naturalists.

I am much pleased that I thought of sending you Forbes' article.
