[262] Mr. James Geikie’s view (“The Great Ice-Age,” 8vo. 1874) that the mixture of the northern and southern forms is due to the destruction of ossiferous strata by streams, which subsequently deposited remains of widely different ages together, is rendered untenable by the fact that they are generally preserved in the same mineral state. It would have been impossible for this to have taken place without leaving decided traces behind in the rolled and water-worn condition of the older series, such as may be seen in the case of the eocene and meiocene fossils in the Red Crag of Suffolk.

[265] I have to acknowledge the kind assistance of Professors Hull and Harkness, Mr. Kinahan, and the Rev. H. M. Close, in correlating the Irish with the English glacial deposits. The reader will find the glacial period most ably treated in Lyell’s “Antiquity of Man.”
