Earthquakes and Other Earth Movements(Illustrated Edition). E-book. Formato PDF John Stewart Milne   -  Ionlineshopping.Com, 2019  - 

THE INTERNATIONAL SCIENTIFIC SERIES VOLUME LV In the following pages it has been my object to give a systematic account of various Earth Movements. These comprise Earthquakes, or the sudden violent movements of the ground; Earth Tremors, or minute movements which escape our attention by the smallness of their amplitude; Earth Pulsations, or movements which are overlooked on account of the length of their period; and lastly, Earth Oscillations, or movements of long period and large amplitude which attract so much attention from their geological importance. It is difficult to separate these Earth Movements from each other, because they are phenomena which only differ in degree, and which are intimately associated in their occurrence and in their origin. Contents     Introduction -- Seismometry -- Earthquake motion discussed theoretically -- Earthquake motion as deduced from experiment -- Earthquake motion as deduced from observation on earthquakes -- Effects produced by earthquakes upon buildings -- Effects produced upon buildings (continued) -- Effects of earthquakes on land -- Disturbances in the ocean -- Determination of earthquake origins -- The depth of an earthquake centrum -- Distribution of earthquakes in space and time -- Distribution of earthquakes in time (continued) -- Distribution of earthquakes in time (continued) -- Barometrical fluctuations and earthquakes; fluctuations in temperature and earthquakes -- Relation of seismic to volcanic phenomena -- The cause of earthquakes -- Prediction of earthquakes -- Earth tremors -- Earth pulsations -- Earth oscillations -- Appendix: List of the principal books, papers, periodicals, which are referred to in the preceding pages.

Indeed, comparatively little attention has been given to this department of archaeology. Literature bearing on it is comparatively scarce. What we have is entirely continental, and consists of a series of reports of different finds with attempts to indicate the uses of the instruments described. In addition to these reports and the actual instruments scattered over various museums, we have at our disposal the writings of the ancient authors themselves. In these a fair number of instruments are minutely described, while many others are named, and here and there points about their shape are mentioned in different places; and by piecing these particulars together and deducing other facts from the nature of the manipulations the instruments are employed in, we can describe in detail, with a tolerable amount of certainty, a surprisingly large number of instruments. It must be confessed that these ancient classics are rather difficult of access, surprisingly so considering that until a few decades ago they were reverenced as works of authority for medical practice; but the fact seems to be that our predecessors were largely content to draw their knowledge of these authors from mediaeval Latin translations. Part of one of the most interesting authors has never been published in the original Greek, and for our knowledge of it we are dependent on a sixteenth-century Latin translation, supplemented, it may be, by fugitive consultations of codices in libraries and museums.Others of the Greek texts have not been reprinted since the sixteenth century, and bristle with the ingenious but at first perplexing shorthand contractions with which the Renaissance typographer imitated the Compendia of the manuscripts. These difficulties can be got over with patience, however, and the waste of gray matter necessary as a preliminary is not out of proportion to the results to be obtained. Even as a quarry for philological materials the medical classics are far from being worked out, and it is surprising how many words one meets with which are not to be found in the best Greek-English dictionaries.
