In the last Number of the Geological Magazine my friend Mr. W. T. Blanford takes exception in very courteous terms to the views I have maintained in regard to the recent elevation of the Highlands of Eastern Asia. I cannot, however, quite grasp how far he agrees or disagrees with me. He does not apparently question the evidence which has so impressed experienced observers like Humboldt, Murchison, Tschihatcheff, Cotta, and Senkofski in regard to the absence of traces of widespread glacial phenomena in the high mountains of the Ural, the Altai, and the Thian Shan ranges, and which apart from all considerations seems to me inexplicable on any other theory than that these mountains did not exist during the so-called Glacial Period.
