“The Expression of the Emotions,” and “ Climbing Plants,” or his numerous scientific memoirs; but we append a list of them, taken from Nature of June 4, 1874.

It is hardly necessary to say that Mr. Darwin has received many scientific honours. He is an honorary member of various foreign scientific societies; he has received the Wollaston Medal from the Geological Society; and from the Royal Society, in 1853, one of the Royal Medals; and, in 1864, the Copley Medal. No man living has exercised so great an influence on biological science. In German scientific catalogues “Der Darwinismus” is a recognised heading; and indeed, there is scarcely one of Mr. Darwin's works which may not be said not only to have been a valuable contribution to our knowledge, but to have pointed out relations hitherto unsuspected, and to have opened up new lines of thought. A list of Mr. Darwin's works ma be found useful for the student, and is appended below. We are glad to be able to add that more than one of Mr. Darwin's sons has already made valuable contributions to science.

Although Mr. Darwin has done so great an amount of scientific work of the very highest class, he has for many years past been in very delicate health. This has prevented him from taking any active part in the management of our scientific bodies, and from mixing much in general society. No man, however, is more beloved by those who have the privilege of his friendship.
