A Glance at the exhibited collections in any of our leading museums, such as the British Museum, the Geological Survey Museum, or the Oxford University Museum, shows that the naming and identification of many of the Mesozoic fossils is in a very unsatisfactory state. The private collector or the student who becomes thoroughly familiar with the fauna of his own district and then goes to these museums to classify and identify it will usually come away with many misconceptions. He finds, moreover, that the various museums contradict one another.

The Bushveld Igneous Complex lately formed the object of a study by the Shaler Memorial Fund Expedition and some members of the staff of the Geological Survey of South Africa, the principal object being to ascertain and fix its relation towards the upper division of the Waterberg Sedimentary System. Their report, published in the Journal of Geology, would seem to furnish the necessary complementary data to fix the origin of the magmatic complex concerned, to a degree of extreme probability, as may be shown in the following.

The Old Red Sandstone occurs in Gower in several inliers which form hills rising above the undulating plateau of Carboniferous Limestone. The chief are Cefn-y-bryn (548 feet) in mid-Gower, Llanmadog Hill (609 feet), the westerly extension of Cefn-y-bryn in north-west Gower, and Rhosilli Down (633 feet) in the extreme west of Gower.

In his fair and courteous paper on the Evishanoran Esker, Tyrone, which appeared in the October issue of this Magazine (p. 451), Professor J. W. Gregory finds himself unable to accept the writer's view of the origin of this glacial feature and re-states at greater length the theory he had earlier formed. Though the area under discussion is very small—only one or two of the 4,000 sq. miles described in my paper on the Glacial Geology of the north-west of Ireland—the importance of the principles involved in this disagreement of views necessitates a reply, however brief, to the criticisms of my interpretation to which I still unrepentently adhere.
