James VI and I was the most prominent homosexual figure in the early modern period. Young has amassed the evidence surrounding James and related it to the larger history of homosexuality. The result is a synthesis of old and new history that illuminates Jacobean politics and challenges many current assumptions about effeminacy, manliness, sodomy, sexual constructs and sexual discourse before the eighteenth century.

This antiquarian volume contains a complete and practical guide to magnetic healing, telepathy, mind reading, clairvoyant hypnosis, mesmerism, animal magnetism, thought transference, personal magnetism, and some other related subjects. Compiled into twenty-five accessible lessons, this guide is ideal for those with little previous experience, and is highly recommended for readers with a keen interest in hypnosis and the extraordinary capabilities of the human mind. Many antiquarian books such as this are increasingly hard to come by and expensive, and it is with this in mind that we are republishing this book now in an affordable, modern, high quality edition. It comes complete with a specially commissioned new introduction on hypnosis.

The field of optics has changed greatly in the past dozen years or so. Partly because of the applied or engineering nature of much of modern optics, there is need for a practical text that surveys the entire field. Such a book should not be a classical-optics text, but, rather, it should be strong on principles, applications and instrumentation, on lasers, holography and coherent light. On the other hand, it should concern itself relatively little with such admittedly interesting phenomena as the formation of the rainbow or the precise deter­ mination of the speed of light. My purpose, therefore, has been to write an up-to-date textbook that surveys applied or engineering optics, including lasers and certain other areas that might be called modern optics. I have attempted to treat each topic in sufficient depth to give it considerable engineering value, while keeping it as free of unnecessary mathematical detail as possible. Because I have surveyed applied optics in a very general way (including much more than I would attempt to incorporate into any single college course), this book should be a useful handbook for the practicing physicist or engineer who works from time to time with optics. Any of the material is appropriate to an introductory undergraduate course in optics; the work as a whole will be useful to the graduate student or applied scientist with scant background in optics.

Since this book was first published in 1977, the major advances in optics have been the maturing of optical communications and the development of in­ tegrated optics. When I was offered the opportunity to prepare a revised edi­ tion, I decided to add chapters on these disciplines to the original work. This book, which was begun long before I joined the National Bureau of Stand­ ards, remains a private venture, written, so to speak, in my basement; there is no official connection with the National Bureau of Standards. I have also taken the opportunity to make some corrections and to add several short sections within the body of the earlier text. The most important of these changes include a discussion of group velocity, phase velocity and group index of refraction to anticipate the need for these concepts in Chap. 9; revision of the section on coherent-optical processing, including what is essen­ tially an optical derivation of the Fourier series; addition of the converging­ beam optical processor; and addition of a section on laser safety. The bulk of the new material comprises three chapters. The first is Chap. 9, "Optical Waveguides". In this chapter, I develop optical waveguide theory primarily on the basis of ray optics and interference in planar waveguides.
