The present volume completes the series of Mr. Walker's anthropological works. To say that they have met with a favorable reception from the American public, would be but a very inadequate expression of the unprecedented success which has attended their publication. "INTERMARRIAGE," the first of the series, passed through six large editions within eighteen months, and "WOMAN," has met with a sale scarcely less extensive. The numerous calls for the present work, have compelled the publishers to issue it sooner than they had contemplated; and, it is believed, that it will be found not less worthy of attention than the preceding. All must acknowledge the interesting nature of the subject treated in the present work, as well as its intimate connexion with those which have already passed under discussion. The analysis of beauty on philosophical principles, is attended with numerous difficulties, not the least of which arises from the want of any fixed and acknowledged standard. The term Beauty is, indeed, generally considered as a vague generality, varying according to national, and even individual taste and judgment. Mr. Walker claims, in his advertisement, numerous points of originality, some of which, on examination, may perhaps prove to have been proposed previously by other writers. Enough, however, will remain to entitle him to the credit of great ingenuity and acuteness. As treated by him, the subject assumes an aspect very different from that exhibited in any other publication. To trace the connexion of beauty with, and its dependance on, anatomical structure and physiological laws--to show how it may be modified by causes within our control--to describe its different forms and modifications, and defects, as indicated by certain physical signs--to analyze its elements, with a view to its influence on individuals and society, in connexion with its perpetration in posterity--all these were novel topics of vast and exciting interest, and well adapted to the genius, taste, and research of our author. In preparing the present edition, it has been thought expedient to make some verbal alterations, and omit a few paragraphs, to which a refined taste might perhaps object, and to bring together in the Appendix such collateral matter, as might serve to correct, extend, or illustrate the views presented in the text. With these explanations, the work is confidently commended to the popular as well as philosophical reader, as worthy of studious examination. CONTENTS.
