Excerpt from d104-Book on Navigation, And, Nautical Astronomy This work is designed to meet the special requirements of officers of the Merchant Service, and to be a complete d104Book on Navigation, eta, for the general student. Candidates for Board of Trade Certificates will find in it all that is needed to cope with the new regulations for the Examinations of Mates and Masters, from the lowest to the highest grades, as regards both practice and principles. The new features in this edition are - (1) Rearrangement, by which the proofs of the various problems are inserted at the beginning of the separate chapter instead of being collected in one chapter at the end of the book. This gives the student a better chance of comprehending each problem. (2) All the astronomical examples are fresh, the necessary rules are given for working them, and, where possible, an example is worked direct from the figure, without using special formula; this will be found of great assistance to those contemplating going in for the "extra" examination. (3) The necessary elements from the Nautical Almanac are embodied in the book in the form found in the N.A., and so will afford as good practice in extracting the data as the possession of the Almanac itself. (4) The chapters on Triqonometry have been entirely rewritten, and the student is shown how to construct both Plane and Spherical Triangles to scale.

Excerpt from A Treatise on Navigation and Nautical Astronomy IN compiling the following Treatise on Navigation and Nautical Astronomy, which the Lords Commissioners of the Admiralty have honoured by accepting as the text-book for use in the Royal Navy, I have endeavoured to combine in one volume information which should be alike useful to beginners and to practical navi gators. The problems dealt with are chiefly those of everyday practice at sea, adapted to the requirements of modern naviga tion, the introduction of swifter vessels rendering it absolutely necessary for the skilful navigator to have at his command every means of determining a ship's position by day and by night. Preceding the practical illustrations of each problem I have placed the theory, which is dealt with in such a way as to be intelligible to those conversant with only Plane and Spherical Trigonometry, without a sound knowledge of which it is im possible to understand the art of Navigation.

An ideal introduction to astronomy and astro navigation. 178 letter size pages packed with full colour illustrations, detailed diagrams and clear explanations. This book focuses on those aspects of astronomy that are essential for a complete understanding of astro navigation - a must for sailors, navigators, nautical colleges and navigation tutors. Teachers and students of many other subjects including geography and mathematics will also find this book interesting, entertaining and very informative. The only book of its kind! The final book of the 'Astro Navigation Demystified' trilogy, Author's preface: Astronomy is a vast and complex subject and when I was taught astro navigation, I often wished my tutor would 'cut to the chase' and focus on only those aspects of astronomy that were relevant. When I taught navigation myself, I searched high and low for an astronomy book that would allow me to pick out just those topics that I needed to teach my students but I was never able to find one. For many years, I meant to write such a book myself to help other astro navigation tutors and students and now, at last, I have found time to do so.
