146 Notes on the Geological Position of the Human these most interesting skeletons lies not in their antiquity,— though they are both unquestionably entitled to be considered prehistoric,—but in their strange anatomical peculiarities, and in the fact that these peculiarities are nearly identical in each. As regards racial affinities, both the Neanderthal and Tilbury men are evidently most nearly akin physically to the robust, but coarse-featured, people of the round barrows of S.W. England, and of the Bronze Age, who are known to have been characterised by large frontal sinuses and supra- orbital ridges, and are considered by Mr. Elton and others to have been of the Finnish or Ugrian stock. And this view as to their race and period gives them just that measure of antiquity that is suggested by the positions in which the two skeletons were found. Note (September, 1884). Sir Richard Owen's work on the Antiquity of Man as deduced from the Tilbury skeleton—an enlargement of his Royal Society paper—being now published (August, 1884), we have the advantage of an authentic exposition of his views. The book is admirably illustrated, and the Neanderthal-like appearance of the Tilbury skull is very strikingly shown. It is evident, however, that the illustrious and venerable naturalist has never visited the Docks himself. Consequently he does not appreciate the difference of age between the older alluvial deposits of the Thames Valley (in which Mr. Worth- ington G. Smith has found so many Palaeolithic implements) and the newer alluvium of Tilbury, as he would otherwise have done, but considers that in the Tilbury skeleton we have the first unquestionably Palaeolithic bones of Man yet dis- covered. I am glad to be able to state that Mr. "Worthington Smith's opinion as to the age of the Tilbury skeleton coincides with my own. In the section of strata sent to Sir E. Owen by Mr. Donald Baynes, one of the engineers superintending the Dock exca- vations, the only inaccuracy in the newspaper accounts worth noting is corrected. The skeleton appears to have been found not at a depth of 82 ft., and at the top of the sand, but at
