I have read your article ("Some disputed Points in Music."--'Fortnightly Review,' July, 1876.) with much interest, except the latter part, which soared above my ken. I am greatly pleased that you uphold my views to a certain extent. Your criticism of the rasping noise made by insects being necessarily rhythmical is very good; but though not made intentionally, it may be pleasing to the females from the nerve cells being nearly similar in function throughout the animal kingdom. With respect to your letter, I believe that I understand your meaning, and agree with you. I never supposed that the different degrees and kinds of pleasure derived from different music could be explained by the musical powers of our semi-human progenitors. Does not the fact that different people belonging to the same civilised nation are very differently affected by the same music, almost show that these diversities of taste and pleasure have been acquired during their individual lives? Your simile of architecture seems to me particularly good; for in this case the appreciation almost must be individual, though possibly the sense of sublimity excited by a grand cathedral, may have some connection with the vague feelings of terror and superstition in our savage ancestors, when they entered a great cavern or gloomy forest. I wish some one could analyse the feeling of sublimity. It amuses me to think how horrified some high flying aesthetic men will be at your encouraging such low degraded views as mine. Believe me, yours very sincerely, CHARLES DARWIN. [The letters which follow are of a miscellaneous interest. The first extract (from a letter, January 18, 1874) refers to a spiritualistic seance, held at Erasmus Darwin's house, 6 Queen Anne Street, under the auspices of a well-known medium:] "... We had grand fun, one afternoon, for George hired a medium, who made the chairs, a flute, a bell, and candlestick, and fiery points jump about in my brother's diningroom, in a manner that astounded every one, and took away all their breaths. It was in the dark, but George and Hensleigh Wedgwood held the medium's hands and feet on both sides all the time. I found it so hot and tiring that I went away before all these astounding miracles, or jugglery, took place. How the man could possibly do what was done passes my understanding. I came downstairs, and saw all the chairs, etc., on the table, which had been lifted over the heads of those sitting round it. The Lord have mercy on us all, if we have to believe in such rubbish. F. Galton was there, and says it was a good seance..." The Seance in question led to a smaller and more carefully organised one being undertaken, at which Mr. Huxley was present, and on which he reported to my father:] CHARLES DARWIN TO PROFESSOR T.H. HUXLEY. Down, January 29 [1874]. My dear Huxley,
