variations, with the values which they should hold in classification,
we do not yet know.

It is not improbable that the reader may leave this brief survey with
the feeling that its admissions of ignorance exceed its affirmations of
certainty, and such is indeed the case, for the law of scientific
validity forbids the statement as fact, of that concerning which the
least element of doubt remains. But the real advance of zoological
knowledge must not thereby be discredited, for it is due to those who
have contributed to it to remember that little more than a generation
ago these problems of life seemed wrapped in hopeless obscurity, and the
methods of investigation which have led to practically all our present
gains, were then but new born, and with every passing year doubts are
dispelled, and theories turned into truths. There was no break in
physical evolution when mental processes began, nor will there be in the
evolution of knowledge as long as they continue to exist.
