A Theory of the Formation of Animals describes the details of formation of man, the structure, development, and physiology. This book is composed of seven chapters and begins with an introduction to a theory of animal formation, namely, the theory of dual constitution. This theory hypothesize that if new types of animal arise through the fusion of two animals of dissimilar kind, then one ought to find among the members of the animal kingdom some forms which might be called Type Animals. Two of these type animals are considered, the archi-annelid Polygordius and the herring (Clupea harengus). The final chapters describe the theoretical aspects of their skeleton and bones. This book is of value to zoologists, theorists, and researchers in the allied fields.

The Nature of Disease, Part III deals with mal-coordination and disease, disease and the nervous systems, and chronic intestinal intoxication. This book discusses the signs and symptoms of disease which is the result of the body's failure to resist infection. The author sees that dehydration is the prevailing abnormal chemico-physical change in the acute stage of disease attack; hydration in the chronic stage. He notes that these two phenomena occur when protein particles in the plasma in disease undergo either a dehydration or hydration process. The author also reviews F.M. Alexander's work on the conscious control of the individual, through psycho-physical mechanism, as a whole body, instead of being reflected in certain anatomical part such as the kidneys, liver, or skin. The author examines the interrelationships between mal-coordination and the nervous system. Such mal-coordination results in chronic intestinal intoxication on nervous manifestations; the author then demonstrates how nerve tissues are damaged by abnormal protein particles in the plasma. The author cites several cases of mal-coordination concerning the nervous system, the vegetative nervous system and the alimentary tract, as well as the role played by a chronic intestinal intoxication in the invasion of the nervous system by micro-organisms. This book can prove informative for cellular biologists, researchers in micro-chemistry or neuro-biology, and doctors in general practice.

The Chemistry and Bacteriology of Public Health deals with public health hygiene. This book reviews the alkalimetry, acidimetry, standard solutions, normal solutions, and the preparation of solutions in public health laboratories, including methods of estimating equivalent weights of substances. In collecting water samples for analysis, the investigator should avoid all sources of extraneous contamination. The Wanklyn's process analyzes organic matter in the water: different tests give quantitative estimates of water contamination or bacterial purity. The authors point that the process of analyzing sewage and sewage effluents are the same as in water analysis except that sewage is diluted with distilled water. The authors also explain how air and water are analyzed, soil analysis being a complex process. The authors discuss milk analysis (fresh, boiled, skimmed, powdered, condensed), butter, cheese, food grains. Microscopic examination of bacteria from samples taken are examined alive, in film preparations, or in sections. The book describes in detail the different types of bacteria, their occurrence, and how these are examined or cultured. This book is intended as a laboratory handbook for students taking up the examination in Public Health. The book can also prove beneficial for social worker, public health officials, and for undergraduate medical students.

Low Blood Pressure: Its Causes and Significance focuses on the important and interesting aspects of low arterial pressure. This book discusses the vasomotor control of arterial pressure; significance of low arterial pressure; autonomic-endocrine influences; and symptomatology of acquired hypopiesis. The parasympathetic or extended vagus system; arteriosclerosis of large vessels; psychical low arterial pressure; and agents causing vascular dilatation are also deliberated. This text likewise covers the exanthematous infections of doubtful etiology; atrophic cirrhosis of the liver; occasional difficulties in diagnosis; and control of low arterial pressure. This publication is intended for medical practitioners and clinicians aiming to acquire knowledge of low arterial pressure and its associations.

The Spleen and Some of its Diseases provides information pertinent to the fundamental aspects of the spleen. This book discusses the role that spleen plays in the etiology of diseases whose most obvious symptoms are evoked by associated or consecutive affections of other organs. Organized into 14 chapters, this book begins with an overview of the anatomy of the spleen, which is entirely covered with peritoneum and is situated behind the fundus of the stomach. This text then describes the first recorded case of splenectomy. Other chapters consider the effect of splenectomy in man and animals upon the general health, upon the blood, and upon the various tissues. This book discusses as well the biochemical investigations upon the spleen and upon the metabolic activities of the body. The final chapter deals with the determination of the functional capacity of all the various organs. This book is a valuable resource for surgeons and physicians.
