My dear Sir
I am sorry you have had so much trouble. I cannot imagine how the sheet could have been lost unless opened by the post office, or unless I sent the sheet by mistake to France or Russia in which case I hope it will be returned & it shall be sent to you.2
In the meantime I send by this post a corrected revise which I trust will serve your purpose—
Dear Sir | yours very sincerely | Ch. Darwin
