To G. B. Sowerby 12 [November 1845]1
Down Bromley Kent
My dear Sir
I intend being in town this day week,2 & with your permission should be very glad on Thursday the 20th to come to your house as early as convenient to yourself & begin our work of going through the shells, it will probably take two or three or more mornings.3 If you can possibly so arrange it, would you oblige me by agreeing & send me note soon & please inform me at which hour; (the earlier the better for my health, after 9 oclock) it will suit you to receive me.— I will bring the specimens & M.S. with me.— You will remember, that you were so good as to acquiesce in my proposal (for in no other way could I permit myself to trespass on your valuable time) of keeping a memorandum of the number of hours I consume & allowing me to in some degree remunerate you for the loss.—
Pray believe me with apologies for troubling you. Yours very faithfully | C. Darwin
Supposing it impossible for you to receive me on Thursday morning the 20th, would you kindly inform me, what three or four first consecutive mornings you could spare; as I am pressed to get on & cannot proceed, till my species are ultimately worked out.
Asks for a meeting in order to go over the shells [which GBS was to describe in the appendix on Tertiary fossil shells in South America].
