s house to open the parcel
(within which was a cover stamped and directed to myself) and return
it to me. This servant, I suppose, opened the box and dropped the glass
tube on a stone floor, and perhaps put his foot on it, for the tube and
shell were broken into quite small fragments. These were returned to me
with no explanation, the box being quite uninjured. I suppose you would
not care for the fragments to be returned or the Dytiscus; but if you
wish for them they shall be returned. I am very sorry, but it has not
been my fault.

It seems to me almost useless to send the fragments of the shell to the
British Museum to be named, more especially as the umbo has been lost.
It is many years since I have looked at a fresh-water shell, but I
should have said that the shell was Cyclas cornea. (402/1. It was Cyclas
cornea.) Is Sphaenium corneum a synonym of Cyclas? Perhaps you could
tell by looking to Mr. G. Jeffreys' book. If so, may we venture to call
it so, or shall I put an (?) to the name?

As soon as I hear from you I will send my letter to "Nature." Do you
take in "Nature," or shall I send you a copy?

LETTER 403. TO C. LYELL. Down, April 27th [1860].

I cannot explain why, but to me it would be an infinite satisfaction to
believe that mankind will progress to such a pitch that we should [look]
back at [ourselves] as mere Barbarians. I have received proof-sheets
(with a wonderfully nice letter) of very hostile review by Andrew
Murray, read before the Royal Society of Edinburgh. (403/1. "On Mr.
Darwin's Theory of the Origin of Species," by Andrew Murray. "Proc. Roy.
Soc., Edinb." Volume IV., pages 274-91, 1862. The review concludes with
the following sentence: "I have come to be of opinion that Mr. Darwin's
theory is unsound, and that I am to be spared any collision between my
inclination and my convictions" (referring to the writer's belief in
Design).) But I am tired with answering it. Indeed I have done nothing
the whole day but answer letters.

LETTER 404. TO L. HORNER.

(404/1. The following letter occurs in the "Memoir of Leonard Horner,
edited by his daughter Katherine M. Lyell," Volume II., page 300
(privately printed, 1890).)

Down, March 20th [1861].

I am very much obliged for your Address (404/2. Mr. Horner's Anniversary
