To J. S. Henslow 14 May 
Down Bromley Kent
My dear Henslow
I have been greatly interested by your letter to Hooker;1 & I must thank you from my heart for so generously defending me as far as you could against my powerful attackers.— Nothing which persons say hurts me for long, for I have entire conviction that I have not been influenced by bad feelings in the conclusions at which I have arrived. Nor have I published my conclusions without long deliberation & they were arrived at after far more study than the publick will ever know of or believe in.— I am certain to have erred in many points, but I do not believe so much as Sedgwick & Co. think. Is there any Abstract or Proceedings of the Cambridge Phil. Soc. published? If so & you could get me a copy I shd like to have one.—2
Believe me my dear Henslow I feel grateful to you on this occasion & for the multitude of kindnesses you have done me from my earliest days at Cambridge.—
Yours affectionately | C. Darwin
P.S. I think I remember your observing that the pistil in different flowers of cowslips & Primroses varies much in length.3 From observations which I have been making I have strong suspicion that they (& Auriculas)4 are dioicous; but I shall know this autumn, for I have marked what I consider the male & female plants.5 Why I mention this to you, is that I have a vague remembrance of your stating that some other plants varied greatly in length of pistil; if so I shd much like to know what, that I might carefully observe them. Do not think of writing unless you can tell me of any such plants.—
Thanks JSH for his defence [see 2794].
He is not hurt for long by what his attackers say. His conclusions were arrived at after long study. He has certainly erred, but not so much as "Sedgwick and Co." think.
Asks JSH to send names of plants that vary greatly in length of pistil.
