9 St. Mark's Crescent, N.W. Wednesday, [August or September, 1867].
Dear Darwin,—I am very sorry I was out when you called yesterday. I had just gone to the Zoological Gardens, and I met Sir C. Lyell, who told me you were in town.
If you should have time to go to Bayswater, I think you would be pleased to see the collections which I have displayed there in the form of an exhibition (though the public will not go to see it).
If you can go, with any friends, I should like to meet you there if you can appoint a time.
I am glad to find you continue in tolerable health.—Believe me yours very faithfully,
ALFRED R. WALLACE.
What do you think of the Duke of Argyll's criticisms, [pg 188]and the more pretentious one in the last number of the North British Review?
I have written a little article answering them both, but I do not yet know where to get it published.—A.R.W.
