    Kurzfassung: 1 Introduction to Coordinate Geometry -- 2 Rate of Change and Differentiation -- 3 Maxima and Minima and Taylor’s Theorem -- Answer to Exercises.
    Kurzfassung: THIS book is intended to provide the university student in the physical sciences with information about the differential calculus which he is likely to need. The techniques described are presented with due regard for their theoretical basis; but the emphasis is on detailed discussion of the ideas of the differ­ ential calculus and on the avoidance of false statements rather than on complete proofs of all results. It is a frequent experi­ ence of the university lecturer that science students 'know how to differentiate', but are less confident when asked to say 'what ix means'. It is with the conviction that a proper understand­ ing of the calculus is actually useful in scientific work and not merely the preoccupation of pedantic mathematicians that this book has been written. The author wishes to thank his colleague and friend, Dr. W. Ledermann, for his invaluable suggestions during the prepara­ tion of this book. P. J. HILTON The University. Manchester . . .

    Kurzfassung: LINEAR equations play an important part, not only in mathe­ matics itself, but also in many fields in which mathematics is used. Whether we deal with elastic deformations or electrical networks, the flutter of aeroplane wings or the estimation of errors by the method of least squares, at some stage in the cal­ culation we encounter a system of linear equations. In each case the problem of solving the equations is the same, and it is with the mathematical treatment of this question that this book is concerned. By meeting the problem in its pure state the reader will gain an insight which it is hoped will help him when he comes to apply it to his field of work. The actual pro­ cess of setting up the equations and of interpreting the solution is one which more properly belongs to that field, and in any case is a problem of a different nature altogether. So we need not concern ourselves with it here and are able to concentrate on the mathematical aspect of the situation. The most important tools for handling linear equations are vectors and matrices, and their basic properties are developed in separate chapters. The method by which the nature of the solution is described is one which leads immediately to a solu­ tion in practical cases, and it is a method frequently adopted when solving problems by mechanical or electronic computers.

    Kurzfassung: This book is written primarily for the family to help solve the meat problem and to augment the food supply. Producing and preserving meats for family meals are sound practices for farm families and some city folks as well-they make possible a wider variety of meats, which can be of the best quality, at less cost. Meat is an essential part of the American diet. It is also an ex­ pensive food. With the costs high, many persons cannot afford to buy the better cuts; others are being forced to restrict the meat portion of the diet to a minimum, or to use ineffectual substitutes. Commercially in the United States, meat means the flesh of cattle, hogs, and sheep, except where used with a qualifying word such as reindeer meat, crab meat, whale meat, and so on. Meat in this book is used in a broader sense, although not quite so general as to com­ prise anything and everything eaten for nourishment either by man or beast. To be sure, it includes the flesh of domestic animals and large and small game animals as well; also poultry, domestic fowl raised for their meat and eggs, and game birds, all wild upland birds, shore birds, and waterfowl; and fish.
