The complexity of medieval & modern pre-metric weights & measures (W&M) in Britain presents an obstacle to scholarly research on Western European econ. history. The problem is: the approx. dimensions of many non-standardized measuring units, used by both the Crown & the regional & local markets, varied from time to time & from place to place; & the dimensions even of standard W&M used in any period are poorly understood. This book will clarify the confusion & bring a new focus to the field of metrology & a new understanding of the units. It includes: tables for rapid identification of all ruling English, Scottish, Irish, or Welsh sovereigns; current English Imperial, Amer. Customary, & metric units; & the basic equiv. for these W&M; & A Dict. of Brit. W&M.

This book is a provocative and invigorating real-time exploration of the future of human evolution by two of the world’s leading interdisciplinary ecologists – Michael Charles Tobias and Jane Gray Morrison. Steeped in a rich multitude of the sciences and humanities, the book enshrines an elegant narrative that is highly empathetic, personal, scientifically wide-ranging and original. It focuses on the geo-positioning of the human Self and its corresponding species. The book's overarching viewpoints and poignant through-story examine and powerfully challenge concepts associated historically with assertions of human superiority over all other life forms. Ultimately, The Hypothetical Species: Variables of Human Evolution is a deeply considered treatise on the ecological and psychological state of humanity and her options – both within, and outside the rubrics of evolutionary research – for survival. This important work is beautifully presented with nearly 200 diverse illustrations, and is introduced with a foreword by famed paleobiologist, Dr. Melanie DeVore.

and by the Librarians and Staffs of the University and the Public Libraries at Southampton. Finally, we wish to thank Mrs H. G. Jerrard and Miss A. J. Tutte for typing the manuscript. Department of Physics H. G. JERRARD D. B. McNEILL University of Southampton 1963 Preface to the fifth ed ition Since the publication of the fourth edition in 1980 advances in technology have led to more precise values of the fundamental physical constants and a movement towards definitions of the fundamental units of mass, length and time based on atomic parameters. More precise definitions of some other units such as the candela have been approved by the international committees. These changes, together with the definitions of several new units have been included in this edition, the text of which has been revised and which now contains over 850 units and dimensionless numbers. The authors wish to thank all those who have helped in this latest compilation by suggestion and kindly criticism and Margaret Wainwright who has had the difficult and tedious task oftyping, retyping and copying the fragmented parts that arise from a text revision. At the time of going to press we believe this book to provide the most complete and up-to-date information of its kind available.
