To William Ogle   17 January 1881

My dear D^r. Ogle.

Very many thanks for your trouble in copying & translating the passages, about which I know nothing.¹

It is always interesting & curious to see the first notices of any phenomenon; but I doubt whether they are of any real use.— The passage, however, about the summer solstice may indicate something new, though in our sunless climate any such phenomenon might be difficult to verify.—

My dear D^r. Ogle | Yours very sincerely | Ch. Darwin
