* * * * * Once again accept my thanks, for I am proud to receive a book from you, who, I know, will some day be the chief of the English Biologists. Believe me, Yours sincerely, CHARLES DARWIN." The loss of him was a manifold loss. He is mourned, and will long be mourned, for many reasons. Some miss only the brilliant investigator; others feel that their powerful and sympathetic teacher is gone; some look back on his memory and grieve for the charming companion whose kindly courtesy and bright wit made the hours fly swiftly and pleasantly along; and to yet others is left an aching void when they remember that they can never again lean on the friend whose judgment seemed never to fail and whose warm-hearted affection was a constant help. And to some he was all of these. At the news of his death the same lines came to the lips of all of us, so fittingly did Milton's words seem to speak our loss and grief-- "For Lycidas is dead, dead ere his prime, Young Lycidas, and hath not left his peer." M. FOSTER. I. ON SOME POINTS IN THE GEOLOGY OF THE EAST LOTHIAN COAST[3]. Footnote 3: From the _Geological Magazine_, Vol. IX. No. 4. April, 1872. By G. W. and F. M. BALFOUR, Trinity College, Cambridge. The interesting relation between the Porphyrite of Whitberry Point, at the mouth of the Tyne, near Dunbar, and the adjacent sedimentary rocks, was first noticed, we believe, by Professor Geikie, who speaks of it in the _Memoirs of the Geological Survey of East Lothian_, pages 40 and 31, and again in the new edition of Jukes's _Geology_, p. 269. The volcanic mass which forms the point consists of a dark felspathic base with numerous crystals of augite: it is circular in form, and is exposed for two-thirds of its circumference in a vertical precipice facing the sea, about twenty feet in height. The rock is traversed by numerous joints running both in a horizontal and in a vertical direction. The latter are by far the most conspicuous, and give the face of the cliff, when seen from a distance, a well-marked columnar appearance, though the columns themselves are not very distinct or regular. They are quadrangular in form, and are evidently produced by the intersection at right-angles of the two series of vertical joints.
