<p>Principles of Metamorphic Petrology provides an introduction to ideas, techniques and approaches in the study of metamorphic rocks. The book begins with basic concepts, but advances further than most other metamorphic petrology texts. Examples of this include the latest chemographic approaches, the correct use of pseudosections and the application of x-ray compositional mapping to metamorphic problems. It also covers advances in thermobarometry and the application of modern geochronological techniques to the absolute timing of tectonometamorphic events. Determination of parent rocks is covered in detail and there is a modern exposition of partial melting reactions, melt extraction and deformation of migmatites. The book includes a large number of references to lead students into independent investigation. A valuable text for advanced undergraduate and graduate courses in metamorphic petrology, that serves as a reference for researchers and exploration geologists.</p>

Excerpt from The Post Office of India and Its StoryWhen I first decided to write a short account of the Post Office of India my intention was to close my story with the amalgamation of the Post Office and the Telegraph Department, which took place in 1913. Publication has been delayed for various reasons, chiefly owing to the outbreak of the war in 1914, and since then many strange things have happened. Consequently I have had to revise several chapters and felt compelled to write one upon the wonderful work done by the Indian Post Office in the Great War. I have also brought the statistical information up to the year 1918. Much of the matter referring to the early posts in India has already been given in Mr. Hamilton's book, An Outline of Postal History and Practice. This is only natural, as we have both drawn from the same sources - namely, the records of the Postal Directorate in Calcutta. I have tried to tell the story of the Post Office in such a way as to be interesting to the general reader as well as useful to the student. The ordinary routine of post office work is not exciting, but the effect of the work, the benefits it confers, the dependence of the public upon its proper execution, are themes to inspire the pen of a romantic writer.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
