y and physiology of the human race; but the novelty of
the results, and the recent date of the communication, induce us to
abstain from hasty comment.

The general physiological comparison of human races, the similarity of
periodic changes, and the average duration of life, are points upon
which we can very briefly touch. Dr Prichard considers the different
ages at which women are said to be marriageable in different climates to
be very much exaggerated. He states his reasons, which do not appear to
us to be very conclusive. The exceptional cases from the normal
physiology would be more interesting, had we space for them, than the
analogies, for which probably all our readers would be prepared. Thus,
among the most curious national anomalies are the Quichuas and Aymaras,
who, from the constant habit of breathing an attenuated atmosphere, have
their chests enormously expanded; the Mandans, who, without any apparent
cause, have the hair grizzled or grey in youth. Among the instances of
individual peculiarity, no one is more extraordinary than the horned
man, whose entire person was covered with a rugged bark, or hide, having
bristles here and there, which hide he was said to shed annually; and
this peculiar form of monstrosity appears to have been capable of
hereditary transmission, as he had six children with a similar covering.
How he procured a wife to bear these children to him does not appear.
The children were, it is to be presumed, not equally successful, as the
breed of these human rhinoceri has become extinct. Some curious
instances of longevity are collected. Of 15 negroes, the names and
residences of whom are given, the average age is 135 years; from
European nations, there are 1310 recorded instances of persons aged from
100 to 110, and 3 from 180 to 190. We do no more than briefly notice
these exceptions, as we are anxious to devote our small remaining space
to what will by many be considered the most interesting portions of the
book, viz. the author's psychological view of the different races of
mankind, or the comparison of their different mental faculties.

"Though inhabiting, from immemorial times, regions in
juxtaposition, and almost contiguous to each other, no two races of
men can be more strongly contrasted than were the ancient Egyptian
and Syro-Arabian races; one nation, full of energy, of restless
activity, changing many times their manner of existence--sometimes
