My dear M^r Judd.

If you are in London & disengaged on Friday the 20^th. would you come & lunch with me at 1 oclock at my Brothers House 6 Queen Anne S^t Cavendish Square—² I should very much like to have $\frac{1}{2}$ an hour geological talk with you— I ought to come to you but it is a rather long journey for me in a rough Cab to S. Kensington.³ If you cannot come to lunch & are inclined to call at any other hour on Friday—I would stay in if you would inform me when you would call.— We return home early on Saturday morning.

I remain. | Yours very faithfully— | Charles Darwin.

Since poor dear Lyell’s death⁴ I rarely have the pleasure of any geological talk with any one.—
