We send you herewith text and manuscript of your paper. The three plates (finished with the exception of the lithographic keys) are, we understand from Messrs Edkins, in your hands. Will you now add the necessary lettering to these plates? We will shortly send you proofs of the tracings, which we shall be obliged if you will number and indicate their places in the text; then return the whole to me and I will supply headlines for the plates and proceed with the printing off.
