PREFACE.
The present work has been undertaken in the belief that by obtaining the co-operation of a considerable number of physicians of acknowledged authority, who should treat subjects selected by themselves, there could be secured an amount of practical information and teaching not otherwise accessible. It was determined to restrict the selection of authors to those of this country—including Canada—not from any want of recognition of the importance of the studies of certain special subjects by European investigators, but because it was felt that the proper time had arrived for the presentation of the whole field of medicine as it is actually taught and practised by its best representatives in America.
It is a matter of importance also that a comprehensive study shall be made of the various forms of disease as occurring among our highly composite population and under our varied and peculiar climatic influences. Of course, in the present work comparative studies of this kind must occupy a subordinate position; yet it cannot fail to enhance both its interest and its value to have the various forms of disease as they occur in this country discussed by those among us who are confessedly the most competent and experienced.
The force of these observations must have been felt by the distinguished men to whom I made application, for with scarcely an exception they joined cordially in the laborious undertaking. I take the greatest pleasure in testifying to the courtesy which has marked all our relations, and which has lessened materially the labor and strain inevitable in the production of such a work.
