Стр. 41 - The upper surface shows the anchylosed calvarial portions of the parietals, and the frontal bones divided by a suture ; the contiguous angles of these four bones are cut off, so as to leave an aperture, occupied by matrix, which may be a fontanelle, or a pineal or parietal foramen. The frontals form the upper borders of the orbits, which are bounded in front by the lacrymal and malar bones, and were not completed behind by bone. Each frontal is narrowed to a point at the suture between the nasal...
Стр. 503 - Norian' series is found in many places covering considerable areas, and apparently resting in discordant stratifications upon the typical Laurentian. Its thickness has been estimated at over 10,000 feet. There is found in certain localities a series of stratified rocks, composed essentially of petrosilex or halleflinta, often passing into ' a quartziferous porphyry. There are found with it strata of vitreous quartzite, and thin layers of soft micaceous schists, besides great beds of hematite, and...
Стр. 461 - But they differ in showing the remarkable fact that these rounded bodies are enclosed in considerable numbers in spherical and oval sacs, the walls of which are composed of a tissue of hexagonal cells, and which resemble in every respect the involucres or sporesacs of the little group of modern acrogens, known as Rhizocarps, and living in shallow water. More especially they resemble the sporocarps of the genus Salvinia. This fact...

With the exception of certain legends, there is no record of a period when the volcanoes were active : two such legends were given. The known volcanic cones were enumerated. They extend from the northern extremity of the island to the 20th parallel of south latitude. Beyond this granite and other primitive rocks occur as far as lat. 22°, south of which the central parts of Madagascar are practically unknown to Europeans. Some crater-lakes...
Стр. 43 - The author said that he was prepared to bring forward conclusive evidence of the correctness of his views from all the areas referred to, and he offered the present paper as a first instalment of the detailed criticism demanded by the Director-General. In a former paper he had maintained that there was no evidence to show that the so-called intrusive granite in Anglesey had altered the Cambrian and Silurian rocks in its immediate vicinity, or that they had been entangled in it as described, but that...
Стр. 375 - Pliocene sea probably extended along the south base of the Alps, extending in long gulfs up the valleys, out of which the marine deposits have been swept by the ice, except in a few protected spots. The paper concluded with a notice of some fossiliferous gritty marl seen in a ravine close to Dormiletto on Lago Maggiore. Although probably in. situ, the mass was not sufficiently exposed to show its relations to the surrounding rocks. 8. " On the Geological Position of the Weka-pass Stone.
