Dear Sir
I am exceedingly obliged to you for your kind note & very obliging offer of examining my specimens2 I will send them tomorrow morning by our carrier to London & thence per coach to Ripley. The one without any apparent shells, is that which I want examining.— On looking round it, you will see the little, indistinct, embedded fragments. The specimens can be returned any time per coach, directed to me at “7 Park St. Grosvenor Sqre”3
I am very much obliged by your kind offer of sending me some slices of shells, but I have not an achromatic microscope.
With very many thanks, believe me | dear Sir | Yours sincerely | C. Darwin To | Dr. W. Carpenter
