Memoir on the Megatherium: Or Giant Ground-Sloth of America, (Megatherium Americanum, Cuvier). E-book. Formato PDF Richard Owen - Forgotten Books, 2017 -
Before commencing the description of the skeleton of the Megatherium, now in London, Plate I., which is the most complete that has yet reached Europe, a brief statement may be premised of the chief steps which have led to the restoration of the species (Megatherium Americanum, Cuvier and Blumenbach) to which it belongs.Cuvier, in communicating to the 'Annales du Muséum' (t. v. 1804) a translation of the first memoir on this subject - that, viz. by Garriga and Bru, published at Madrid in 1796, - gives all the requisite details respecting the discovery of the skeleton therein described, and adds his own more important deductions as to its affinities from an examination and comparison of the plates of the Spanish work.
On the AtoOn the anatomy of vertebratesmy of Vertebrates: fishes and reptiles. E-book. Formato PDF Richard Owen - Forgotten Books, 2017 -
In the choice of facts, as then and since acquired by science, I have been guided by their authenticity and their applicability to general principles. In the first, regard has been had to the agreement of several observers, or to the nature of the fact as making it acceptable on the testimony of a single expert. Appearances that require helps to vision are those that call for multiplied concurring testimony, and on such alone are offered the descriptions and illustrations of the microscopical characters of tissues premised to most of the chapters.
The Electron Theory of Matter. E-book. Formato PDF Owen Willans Richardson - Forgotten Books, 2017 -
His book is based on a course of lectures which I have delivered to graduate students at Princeton University during the last few years. My aim has been to exhibit the extent to which the fundamental facts of physical science may be coordinated by means of the conception of the electron and the laws of electrodynamics. In developing the subject I have started from the most elementary beginnings, and I have therefore found it necessary to include much matter which is to be found in any ordinary text-book of the theory of electricity and magnetism. It is hoped that the lack of conciseness thereby involved may be more than atoned for by the wider circle to which the book may appeal. The course of lectures at Princeton on which the book is founded proved useful as an introduction to the methods of modern mathematical physics in addition to forming a presentation of the results of recent physical discovery. The broad scope of the subject makes it imperative that a good deal of selection should be exercised as to the nature and treatment of the topics considered. In determining these, consideration has been given to importance, interest, and instructiveness, roughly in the order named. The necessary incompleteness is remedied to some extent by references to scientific papers and to other works. These references are intended to supplement the discussion in the text rather than to exhibit the historical development of the subject. Thus many important papers are not referred to. I have tried, however, to be as accurate as possible in any statements which deal specifically with historical matters.
