finds in the adult animal is only 30 deg.--_i. e._ 40 deg. short of the
smallest facial angle in the human race! We should hence be led to
suspect a proportionate difference between the infant and adult mind;
but the psychological development of infants is a subject which has been
strangely neglected by philosophers. A clever Italian authoress who has
written an anonymous work upon education, gives as the reason for the
dearth of writing on this subject, that philosophers are not mothers,
and that mothers are not philosophers. Be this as it may, few theorems
appear to us more promising of interest. The struggle of internal force
with external resistance, the feelings manifested in the acquisition of
new powers, the impressions made by objects seen for the first time, and
first questions asked, form grounds for induction as to the psychology
of man, which, thanks to the chartered tyranny of nursery-maids over
philosophers, have been grossly neglected.

After going through other points of physical difference in human races,
with which, being for the most part matter of anatomical detail, we
shall not trouble our readers, Dr Prichard concludes:--

"On surveying the facts which relate to difference in the shape of
the body, and the proportions of parts in human races, we may
conclude that none of these deviations amount to specific
distinction. We may rest this conclusion on two arguments. First,
that none of the differences in question exceed the limits of
individual variety, or are greater than the diversities found
within the circle of one nation or family. Secondly, the varieties
of form in human races are by no means so considerable, in many
points of view, as the instances of variation which are known to
occur in different tribes of animals belonging to the same stock,
there being scarcely one domesticated species which does not
display much more considerable deviations from the typical
character of the tribe."

The only observation we shall make upon this is, that, as before stated,
the test of identity of species being the power of continued
reproduction, not the slightest evidence having been ever offered that
all the various human races have not _inter se_ this power, but the
contrary having been proved in every case within human experience, none
of the deviations _can_ amount to _specific_ distinctions.
