My dear Gray
I thank you much for the 2 seeds of Megarrhiza: I hope that they may germinate for I shd. very much like to see a longitudinal section & the proportion of the parts, when the (apparent) root is only or of inch out of the seed-coats.
You must not suppose that what is obvious to you is so to me; for as the confluent petioles of the Cots. of the Delphinium are not tubular at first, I was astonished to see the young leaves coming out of a hole or slit at their base.
Very many thanks for all your information about the Megarrhiza, the germination of which has interested me greatly.—
I was much amused by your little article on the Philadelphia lawyer. You are a first-rate hand in touching up a fool.— The lawyer is a cool man in trying to make me out a rogue; but this seems the fashion & according to Mr S. Butler in the Athenæum I am a rogue of the deepest dye, because I forgot to state that Dr Krause had altered his article on Erasmus Darwin before sending it to England for translation.
Ever yours sincerely | Ch. Darwin
