Far better face the fact that race still baffles us almost completely.
Yet, breed is there; and, in its own time and in its own way, breed will out.
[Footnote 2: The reader is advised to consult also the more comprehensive study on _Evolution_ by Professors Geddes and Thomson in this series.] Race or breed was a moment ago described as a factor in human nature.
But to break up human nature into factors is something that we can do, or try to do, in thought only.

In practice we can never succeed in doing anything of the kind.

A machine such as a watch we can take to bits and then put together again.

Even a chemical compound such as water we can resolve into oxygen and hydrogen and then reproduce out of its elements.

But to dissect a living thing is to kill it once and for all.
