Down, Bromley, Kent, S.E.

March 6

My dear Sir

I am extremely much obliged to you for your great kindness and all the large amount of trouble which you have taken to oblige me.2 Your information is sufficient: I feared that Dr. C. might not have given whole case.3

With very sincere thanks | Yours very faithfully | Ch. Darwin
