editors of the last named publications to be worthy of note, I have
accepted them, on their authority, as noteworthy.

No attempt is made in this book to deal with the transmission of
ability of the very highest order, as the data in hand do not furnish
the required material, nor will the conclusions be re-examined at
length that I published many years ago in "Hereditary Genius." Still,
some explanation is desirable to show the complexity of the
conditions that are concerned with the hereditary transmission of the
highest ability, which, for the moment, will be considered as the
