My Dear Darwin

Your note of the 15^th ult. just in.¹

I have read it to two good observers,—who say the “vermiform piles” are common enough here,—and I should think, if not as common as with you thro’ the season, it was owing to interruption in the dry part of our hot summer.

I know nobody now at hand here who could give a comparison with your country. Perhaps I may find some one in Canada to ask.

Now, pray don’t run off on some other track till you have worked out and published about Drosera & Dionæa²

My wife³ joins in kindest regards to you and yours | Ever Yours sincerely | Asa Gray
