IAU Colloquium 165, Dynamics and Astrometry of Natural and Artificial Celestial Bodies, was held in Poznan, Poland, in July 1996, bringing together over 200 scientists from 27 countries who discussed their work in 179 oral and poster presentations. The present volume contains 83 of the papers presented at the meeting. The meeting brought together specialists from diverse fields who focused on the very close collaboration between dynamics and astrometry, where one discipline contributes to the progress of the other. The oral sessions were organized into general categories pertaining to: solar system dynamics; new observational techniques, catalogues, and astrometry; dynamics and observational problems of artificial satellites and space debris; rotation of solar system objects; reference systems and astronomical standards; new mathematical techniques; and three all-day poster sessions. This volume is divided into seven parts, comprising 83 contributions, a list of participants and an index.

Facsimiles of primary texts on eighteenth-century midwifery and childbirth. Gives readers an understanding of midwives, midwifery students, and women in labour. This twelve-volume collection comprises pamphlets, treatises, lectures for midwifery students, texts on the establishment of lying-in hospitals, and catalogues of obstetrical apparatuses collected by male-midwives. Important themes include medical developments, 'freaks of nature', women's 'conduct' and the legal and societal implications of birth and motherhood. Gender is a central issue in works that address the efficacy and propriety of midwifery practice and whether men or women are best suited to the job.

"Fundamental Astronomy and Solar System Dynamics," a program of invited papers honoring Professor Walter Fricke, who for thirty years has been Director of the Astronomisches Rechen lnstitut in Heidelberg, was held at the Thompson Conference Center of the University of Texas at Austin on Wednesday 27 March 1985 on the occasion of his seventieth birthday and retirement as Director of ARl. Professor Fricke's contributions to astronomy encompass the areas of galactic dynamics, radial velocities, stellar statistics. the fundamental reference system and the constant of precession. Participants were welcomed to the Uni versi ty of Texas by Professor J. Parker Lamb, Chairman of the Department of Aerospace Engineering and Engineering Mechanics. The presentations ranged from discussions of astrometric problems concerned with the reference system, the constant of precession, major and minor planet observations, planetary ephemerides and lunar and satellite laser ranging, to a study of disc galaxies in massive halos. The program concluded with a review of Professor Fricke's career. The three sessions were chaired by Victor G. Szebehely, Carol A. Williams and Jay H. Lieske. The participants in this meeting, and in the Division on Dynamical Astronomy meeting that followed, were happy that Professor Fricke was able to attend. His presence at these meetings, as well as his thoughtful comments, were greatly appreciated. We are pleased to acknowledge the support of the Center for Space Research, the Department of Astronomy and the Department of Aerospace Engineering and Engineering Mechanics of the University of Texas at Austin.

Expanded and updated to include an additional 44 species, this is a handy guide to those fishes that are likely to be observed by anybody visiting or diving on the coral reefs of the Caribbean, the Indian Ocean, and the Pacific to a depth of sixty meters. Accessible to amateur marine life enthusiasts, this book is the first comprehensive guide of its kind. It enables the reader to quickly identify 2,118 species of fish and includes over 2,500 color illustrations depicting the major forms of each species--male, female, immature, or geographical varieties. The text proceeds according to region, depicting each species and its varieties, and offering information on its geographic range and where on the coral reef itself the fish may be found. Important identification characteristics are highlighted on every color plate.

Scholars of the British Enlightenment who study obstetrical history traditionally focus on the rise of the male-midwife and competition between the sexes. This set comprises pamphlets, treatises, lectures for midwifery students, texts on the establishment of lying-in hospitals, and catalogues of obstetrical apparatuses collected by male-midwives.

Gender is a central issue in works that address the efficacy and propriety of midwifery practice and whether men or women are best suited to the job. Works from popular or low culture feature: advertisements for midwives' services, medicinal cures, and monster births; texts on murderous female midwives and lewd male-midwives; and the 1726-27 correspondence on the 'rabbit-breeder', Mary Toft. Several significant works written by women stand out such as Catherine Elizabeth Weld's report of legal proceedings against her husband on the charge of impotency; and Elizabeth Nihell's Treatise on the Art of Midwifery (1760).
