On the Evidences of a Submergence of Western Europe, and of the Mediterranean Coasts, at the Close of the Glacial or So-Called Post-Glacial Period, and Immediately Preceding the Neolithic or Recent Period . a Bruxelles, 1872, Plate 31. 928 PROFESSOR J. P&ESTWICH ON THE EVIDENCES OP A SUBMERGENCE entrance to the caves, and destroyed portions of the Eaised Beach, I shouldtherefore consider the remains of the animals here found in the Argile d blocaux tobe foreign to that deposit, and as belonging to the Mammoth group. It was only nearthe base of this angular rubble (2) that these derived remains were found. Another point of analogy rendered evident by the sections of M. Ditpont, is theabrupt transition from the Palaeolithic to the Neolithic deposits. This agreesprecisely with what we have witnessed on the English coasts, where the stanniferous,gravel of Cornwall and the angular rubble of Devonshire sharply separate the RaisedBeaches and sands of Quaternary age from the alluvial deposits and forest growth ofthe recent period. The following (fig. 13) is one of the sections,^ where the twodeposits are seen in superposition. Pig. 18.—-Section of the Trou du Bureau, Montaigle (Dupont). R. 1. Debris -with Neolithic flints, and animal remains of the same age. 2. Clay with angular fragments {Argile a blocaux). 3. Fluviatile beds with animal remains of Quaternary age. [I am not prepared with evidence relating to the Eubble-drift eastward throughGermany, or to the northward of Belgium, but I may mention that Dr. Lorte, ofUtrecht, has called my attention to a deposit which covers some parts of NorthHolland, and is described by him under the head of Phenomenes pseudo-glaeiaires.#This drift, which seems to represent some phase of the Bubble-drift, is referred byDr. Lome to the warp of Trimmer, and trail of 0. Fisher.—J. P., July, 1893.] The Paris Basin.—Several sections of this drift have been noticed in the ParisBasin where deep valleys cut through high plains of Tertiary s
