My dear Sir.

We are interested on so many points in common that I should much like to be permitted to make your personal acquaintance.— But the only time on which I could call would be on Sunday morning about 10 o’clock—& I would leave before eleven.

Perhaps this would not be convenient to you but should it be so will you kindly send me a line here

Believe me dear Sir | Yours faithfully | Ch. Darwin

P.S. I am bound to add that my health is so doubtful that I may fail to appear, if you permit me to come—& then you will understand that I am not well.
