This introductory text emphasizes Feynman's development of path integrals and its application to wave theory for particles. Suitable for undergraduate and graduate students of physics, the well-written, clear, and rigorous text was written by two of the nation's leading authorities on quantum physics. A solid foundation in quantum mechanics and atomic physics is assumed. Early chapters provide background in the mathematical treatment and particular properties of ordinary wave motion that also apply to particle motion. The close relation of quantum theory to physical optics is stressed. Subsequent sections emphasize the physical consequences of a wave theory of material properties, and they offer extensive applications in atomic physics, nuclear physics, solid state physics, and diatomic molecules. Four helpful Appendixes supplement the text. Dover (2014) republication of the edition originally published by Allyn and Bacon, Inc., Boston, 1970.

Latin is one of two acceptable languages for describing new plants, and taxonomists must be able to translate earlier texts in Latin. Providing a simple explanation of Latin grammar along with an in-depth vocabulary, this is an indispensable guide for systematic botanists worldwide. All relevant parts of speech are discussed, with accompanying examples as well as worked exercises for translating diagnoses and descriptions to and from Latin. Guidelines for forming specific epithets are also included. The authors cross-reference their grammar to Stearn's Botanical Latin and to articles in the International Code of Nomenclature for Algae, Fungi and Plants. The comprehensive vocabulary is enhanced with terms from recent glossaries for non-flowering plants – lichens, mosses, algae, fungi and ferns – making this an ideal resource for anyone looking to hone their understanding of Latin grammar and to translate botanical texts from the past 300 years.
A Complete and Practical Treatise for the Use of the Perfumer and Cosmetic Manufacturer, Covering the Origin and Selection of Essential Oils and other Perfume Materials, The Compounding of Perfumes and the Perfuming of Cosmetics
A Complete and Practical Treatise for the Use of the Perfumer and Cosmetic Manufacturer, Covering the Origin and Selection of Essential Oils and other Perfume Materials, The Compounding of Perfumes and the Perfuming of Cosmetics
First published in 1915, this volume contains a detailed guide to the preparation and manufacture of perfumes and cosmetics, originally intended for professional perfumers and cosmetic manufacturers. Although old, this volume contains a wealth of practical and useful information, and it is highly recommended for modern readers with an interest in perfumery. Contents include: "The History of Perfumery", "About Aromatic Substances in General", "Odors form the Vegetable Kingdom", "The Aromatic Vegetable Substances Employed in Perfumery", "The Animal Substances Used in Perfumery", "The Chemical Products Used in Perfumery", "The Extraction of Odors", "The Special Characteristics of Aromatic Substances", etc. Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with a specially commissioned introduction on essential oils.
Horrible as were the atrocities of which the monsters of the French Revolution were guilty, they paled before the fiendish outrages committed by their black imitators in Hayti. Indeed, for some six years the island presented a saturnalia of massacre, attended with indescribable tortures. It may be admitted that the retaliation inflicted by the maddened whites after the first massacre was as full of horrors as were the outrages perpetrated by the blacks, and both were rivalled by the mulattoes when they joined in the general madness for blood. The result was ruin to all concerned. France lost one of her fairest possessions, and a wealthy race of cultivators, many belonging to the best blood of France, were annihilated or driven into poverty among strangers. The mulattoes, many of whom were also wealthy, soon found that the passions they had done so much to foment were too powerful for them; their position under the blacks was far worse and more precarious, than it had been under the whites. The negroes gained a nominal liberty. Nowhere were the slaves so well treated as by the French colonists, and they soon discovered that, so far from profiting by the massacre of their masters and families, they were infinitely worse off than before. They were still obliged to work to some extent to save themselves from starvation; they had none to look to for aid in the time of sickness and old age; hardships and fevers had swept them away wholesale; the trade of the island dwindled almost to nothing; and at last the condition of the negroes in Hayti has fallen to the level of that of the savage African tribes. Unless some strong white power should occupy the island and enforce law and order, sternly repress crime, and demand a certain amount of labour from all able-bodied men, there seems no hope that any amelioration can take place in the present situation.
