Apophthegms on the nature of the Science of Ethnology 559-566 NATURAL HISTORY OF MAN. [Illustration: Fig. 1.] INTRODUCTION. Previous to entering upon the details connected with the varieties, and affinities of the human species, it is advisable to explain the meaning and full import of certain terms that are likely to be of frequent occurrence. It is only, however, so far as an _explanation_ is required, that any remarks will be made. The questions themselves, although necessary and preliminary, are well capable of being isolated from the properly descriptive portions of the subject, and of forming separate sections of ethnological science; a separation which is fully justified by their great range and extent.
