CONSIDERED FROM THE STANDPOINTS OF COMPARATIVE ANATOMY, PHYSIOLOGY, PATHOLOGY AND BACTERIOLOGY

Preface

In his work on the “ Human Species,” Hopf compares the structure, functions and diseases of man with those of animals. It must not be taken, however, that the volume is simply a collection of facts and details. A glance at the headlines of the pages will reveal the wide extent of the ground covered. After discussing the distribution of mankind, the ancestors of man, the structure and functions of the various tissues, Hopf deals with such interesting questions as psychology, the origin of the mind, emotions and their expression, social customs, marriage, communism, modesty, shame, religion and art. He then proceeds to consider the diseases of man and animals, the parasites common or peculiar to each, and concludes with a fascinating chapter on self-help in animals and primitive man. Realising that such aspects of the subject will appeal to the general reader, the text has been shorn of scientific terminology as much as possible.

In preparing an English translation the Editor has tried to follow out the general idea of the author, and therefore no apology is needed for the terminology employed. Difficulties have arisen in adapting the German classification to the English reader, and in some instances it has been necessary to retain terms and distinctions not usually current in English books.

few alterations and additions have been made, but these in no way affect the deductions, theories or views of the German author. ' Wherever possible, German quotations from English works have been verified, and the original English wording cited. There is little doubt but that those who study this work will find in it a fund of information presented in an interesting^ though concise, manner.
