    PREFACE TO THE SECOND EDITIOK 1 HE rapidity with which the first edition of this book was ex- hausted would seem to have left little opportunity for an extended re\4sion. An author must needs get somewhat away from the atmosphere of his work before he can critically study its defects and relieve it of its original crudities. It was with this feeling that the author approached the task of revising this book for the second edition, and he had supposed that accordingly there would be small chance for material change in the text, but he had not gone far without realizing that almost every page required some altera- tion and that several chapters had to be practically re-written. This is only in accordance with the rapid evolution of thought upon this important subject, and it is a healthy sign of the progress of the profession when an author finds his work, however con- scientiously written, so soon out of date. This applies, of course, more to the details than to the fundamentals of the subject, though it must not be forgotten that the varying changes in the details must eventually affect the fundamentals. The present edition is sent out WTith the realization that it is not free from the usual limitations of authorship, and yet it is the best of which the author is capable at the present time. He can only bespeak for it the same cordial reception that was generously given the first edition —a reception which has placed him beyond measure a debtor to the profession at large. C. N. J.
