substance
as deducible from its properties under varying conditions. Only,
admittedly, as yet the endocrine label is but roughly qualitative and
most crudely quantitative, whereas the chemical formula is the essence
of the exact.

However, the fact remains that though we are only upon the first
rungs of the ladder, we are upon the ladder. The horizon undoubtedly
broadens. We possess a new way of looking upon humanity, a fresh
transforming light upon those strange phenomena, ourselves. Of the
ugly achievements of that dreadful century, the nineteenth, the most
illuminating was the discovery of itself as the _ape-parvenu._ Yes,
we are all animals now, it said to itself, and set its teeth in the
cut-throat game of survival. But there was no understanding in that
evil motto of a disillusioned heart. The ape-parvenu, desperately
lonely and secretive, has still to understand himself.

Let us be clear if we can. There is perhaps a certain presumption in
the phrase, the endocrine type. It is ambitious, and perhaps will not
fulfill its promise. But it is useful because it points a parallel and
an ideal. As Wilhelm Ostwald never tired of repeating, H_{2}O is a
complete shorthand record for the bundle of qualities commonly known
as water. It is an example of that highest task of mind, synthesis.
It is the highest synthesis of the studies of the internal secretions
that certain combinations of them, permutations and blendings of
them, are responsible for those unique wonders of the universe,
personalities.

The riddle of personality! Are we at last upon the track of its
uncovering? That elusive mystery, which philosophers have wrapped in
the thousand veils of Greek and Latin words, and psychologists, even
unto the third and fourth generation of Freudians, have floundered
about in, moles before a dazzling sun, is it to be unwound for our
inspection? Think of the human soul. What an invisible, intangible
chameleon is its true reality! Watch it, and you see something that
seems to uncurl and expand like a feather with exultation and delight
and joy, to contract and stiffen into a billiard ball with fear and
pride, shrewd caution and vigilant malevolence, to rear back and spark
fire like lightning with anger and temper, and to crawl and slither
with abjection and smirking slyness, when it needs to. This multiplex
Thing-Behind-Life, are we really about to dissect it into its
elements?

Personality embraces much more than merely t
