To Robert Fitch 6 January 
Down Farnborough Kent
If you will have now the kindness to lend me your Pollicipes,1 I shd be very much obliged.— I have given up in despair the lot from Copenhagen;2 but I now have 40 or 50 specimens here. I hope that you will allow me to keep your specimen a week for I really shall hardly be able to compare all my specimens under this time.—
If you have any separate valves3 & wd be pleased to entrust them to me, I shd be grateful for the assistance.
I will immediately on receipt of the specimen acknowledge its arrival. & return stamps for its registry &c.—
I beg to remain | Dear Sir | Yours faithfully | C. Darwin
Asks to borrow some more cirripede specimens.
