INTRODUCTION.

Since the publication of my work on Hereditary Genius in 1869, I have written numerous memoirs, of which a list is given in an earlier page, and which are scattered in various publications.  They may have appeared desultory when read in the order in which they appeared, but as they had an underlying connection it seems worth while to bring their substance together in logical sequence into a single volume.  I have revised, condensed, largely re-written, transposed old matter, and interpolated much that is new; but traces of the fragmentary origin of the work still remain, and I do not regret them.  They serve to show that the book is intended to be suggestive, and renounces all claim to be encyclopedic.  I have indeed, with that object, avoided going into details in not a few cases where I should otherwise have written with fulness, especially in the Anthropometric part.  My general object has been to take note of the varied hereditary faculties of different men, and of the great differences in different families and races, to learn how far history may have shown
