PREFACE
In describing the symptoms of disease and the anatomy of the body, it has been necessary to use terms that are technical in character. To render the text perfectly intelligible to the lay mind, a glossary has been appended which contains the definitions of all words difficult of interpretation.
The facts presented and the arguments made are intended primarily for general intelligence; but, since the facts are corroborated, it is hoped that earnest investigation will follow by those who seek truth in its every phase. The author claims no originality in theory, either philosophical or physiological, but she insists upon the recognition of her thoroughness of detail in research, and of her confidence in practical demonstration.
