Book Description

Excerpt from The Geological Magazine, or Monthly Journal of Geology, 1917, Vol. 4: With Which Is Incorporated the Geologist, Nos; 631 to 642; Decade Vi The unravelling of the story of early man is indeed a continual struggle with the fragmentary evidence of casual discoveries. Much of it still consists in the balancing of probabilities. The value of the influence of attractive summaries like those before us, adapted for the general reader as well as the specialist, cannot therefore be too highly estimated. No one can tell how' and where their influence may preserve the next important disco very from thoughtless destruction.

Book Description

Excerpt from The Geological Magazine, or Monthly Journal of Geology, Vol. 3: With Which Is Incorporated "the Geologist"; January December, 1866 But as sudden and rapid growth° 1s seldom altogether!° healthy, so the exuberance of vitality in the young science has ever and anon originated errors which have, at. Times, checked its career. Hasty generalizations, and loosely formed theories, advanced by would-be leaders Of the science, have occasionally le_d their followers into wrong, trains Of thought, whereby they have failed to see the true bearing of facts brought before them, and have ceased, for a time, to advance their knowledge, on account of the incorrectness or insufficiency of their, principles Of explanation. One great means of correcting existing errors and preventing for the future the general adoption of others, is to maintain for the scientific world an easily accessible medium of discussion. In order, however, to render the discussion of any Geological topic useful, it must be based° In the first instance upon accurately recorded observations, and as every year increases the number of Observers, it also becomes important to enlarge the Opportunities of preserving the results of their labours. The aim of the geological magazine, since its Commencement in 1864, has been _to supply this need, and to supplement, as far as possible, the authoritative and Old-established Journal of the Geological Society.

Book Description

Excerpt from The Geological Magazine, or Monthly Journal of Geology, Vol. 4: January December, 1907 Director of the Geological Survey of Scotland, however remote his field of work might be, his ever-active pen and pencil kept him in touch with the world at large. The Story of a Boulder. Gleanings from the Notebook of a Geologist his Memoir of Edward Forbes The Scenery Of Scotland viewed in connection with its Physical Geology (1865, 3rd edition and many other of his writings 1 were read with the keenest enjoyment. We published in February, 1890, a portrait of Sir A. Geikie and a brief summary of his work up to that date, just prior to his election for the first time as President of the Geological Society. The addresses which he gave during the two years that he occupied the chair formed the nucleus Of perhaps his most important work, published in 1897 under the title of The Ancient Volcanoes of Great Britain, two volumes, beautifully printed and illustrated. In the same year he established the Summary of Progress Of the Geological Survey, an annual publication which gives an official record of the work done by this institution. He prefaced the first number with an account of the Origin and History of the Geological Survey and Museum, a subject which he had dealt with more personally in 1895 in his Memoir of Sir Andrew Crombie Ramsay. While still Director General he edited in 1899 a third volume of Hutton's Theory of the Earth, from the ms. That had long been in the possession of the Geological Society.

Book Description

Excerpt from The Geological Magazine, or Monthly Journal of Geology, Vol. 3: January December, 1896 OR several years I have been engaged in investigating the Dinosaurs of North America, where these extinct reptiles were very abundant during the whole of Mesozoic time. The results of my study have been published from time to time, and I have already had the honour of presenting some of these to the British Association. In carrying out this investigation so as to include the whole group of Dinosaurs, wherever found, and bringing all under one system of classification, it has been necessary for me to study the remains discovered in Europe, and I have made several visits to this country for that purpose. In comparing the forms known from the two continents, certain important differences, as well as some marked resemblances between the two, have been observed, and placed on record. In concluding my investigations of the North American forms, I have fortunately been able to make restorations of the skeletons of quite a number of very complete type specimens, and this has proved a most instructive means of comparing those from different horizons, and of different groups, among the known Dinosauria of America. The success Of this plan rendered it very desirable to extend it, if possible, to the best-known forms of European Dinosaurs. This I have been enabled to do in a few instances, and the main object of the present paper is to lay these latest results before you.

The Geological Magazine, Or Monthly Journal of Geology, Vol. 4


Book Description

Excerpt from The Geological Magazine, or Monthly Journal of Geology, Vol. 4: With Which Is Incorporated "the Geologist;" January-December, 1877 Elevation and Depression of Strata - The movements of the earth's crust are generally allowed to be due to the loss of heat from within it, whether by the wrinkling or the crushing of the crust on a con-3 tracting nucleus, or by any other means. But at the beginning of geologic time the temperature was much more elevated above that of its surrounding medium than at present, and consequently cooling or the loss of heat must have gone on more rapidly than at present, and from this follows a more rapid progress of those movements of upheaval and subsidence depending on this cooling. Thus elevation and depression of strata must have occurred with greater rapidity m the earlier than ln the later stages of our planet's history. Summary. -we have now shown that the decreasing energy of the sun and of the earth must have led to diminishing rapidity in the action Of three of the main factors of geologic change, viz. On the denudation, reproduction, and the elevation and depression of strata. In spite of all fluctuation resulting from more than usually rapid conversions of potential into kinetic energy, the loss of energy continually proceeds, and as continually is accompanied by a decrease in the rate of geologic change, just as certainly as the greater periodical activity in the solar radiation once every 112 years ives rise to exactly Opposite results.
