The third revised editions of Jeffrey North’s two volume classic are newly reissued for 2018 to make them available to Spink customers for the first time in over ten years. Volume I includes hammered coins of the early Anglo Saxon, Viking, Regional Kings, Norman and Plantagenet periods up to the reign of Henry III, including 20 plates with hundreds of coin images, covering the dates c600 to 1272. Volume II covers the coinages of Edward I to Charles II from 1272-1662, the principal amendments to the third edition being in the coinages of 1279-1351 and the provincial issues of Charles 1; much new information was incorporated into the relevant sections in 2000 on the strength of important studies including the base shillings of Edward VI, the milled coinage of Elizabeth 1, the Tower shillings of Charles 1 and the mint of York of Charles 1.

Cancer is a group of different diseases (more than 100) characterised by uncontrolled growth and spread of abnormal cells. Cancer can arise in many sites and behave differently depending on its organ of origin. If a cancer spreads (metastasises), the new tumour bears the same name as the original (primary) tumour. Significant progress has been made in recent years in the battle against cancer and in understanding its underlying biological mechanisms. This research progress has resulted in many experimental treatments and cures. This book presents new and important research from around the world.

Treatise on Geophysics: Mantle Dynamics, Volume 7 aims to provide both a classical and state-of-the-art introduction to the methods and science of mantle dynamics, as well as survey leading order problems (both solved and unsolved) and current understanding of how the mantle works. It is organized around two themes: (1) how is mantle convection studied; and (2) what do we understand about mantle dynamics to date. The first four chapters are thus concerned with pedagogical reviews of the physics of mantle convection; laboratory studies of the fluid dynamics of convection relevant to the mantle; theoretical analysis of mantle dynamics; and numerical analysis and methods of mantle convection. The subsequent chapters concentrate on leading issues of mantle convection itself, which include the energy budget of the mantle; the upper mantle and lithosphere in and near the spreading center (mid-ocean ridge) environment; the dynamics of subducting slabs; hot spots, melting anomalies, and mantle plumes; and finally, geochemical mantle dynamics and mixing. - Self-contained volume starts with an overview of the subject then explores each topic in detail - Extensive reference lists and cross references with other volumes to facilitate further research - Full-color figures and tables support the text and aid in understanding - Content suited for both the expert and non-expert

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 16 (The Griggs Volume). David Tressel Griggs was born October 6, 1911, in Columbus, Ohio. His parents were Robert Fiske and Laura Amelia Tressel Griggs. His father was a widely known professor of botany and a leading ecologist and environmental conservationist at a time when these viewpoints were less familiar than they are today. David was an undergraduate at Ohio State University in 1930 when he participated in a National Geographic Society expedition, led by his father, to the Valley of Ten Thousand Smokes. This Alaskan experience and the encouragement he received from a gifted and enthusiastic teacher, Professor Edmund M. Spieker, led him to choose for his life work the application of physics to the problems of the earth. After a year of graduate studies in geology at Ohio State, David moved on in 1933 to Harvard, where a new progTam of high-pressure studies devoted to geophysical problems had just been initiated under the inspired guidance of Percy W. Bridgman, pre-eminent leader in the experimental exploration of the physics of very high pressures and in the philosophical analysis of the logical processes of scientific thinking.
