orld's greatest ideas have come to light first
in the forgotten manuscripts of people of this type who died without
showing their writings to any one. Evidently they did not consider them
of sufficient importance or did not care as much about publishing them
as about putting them down.

An Inveterate Reader

Step into the reference rooms of your city library on a summer's day
and you will stand more chance of finding examples of this extreme type
there than in any other spot.

You may have thought these extreme types are difficult to locate, since
the average American is a combination. But it is easy to find any of
them if you look in the right places.

In every case you will find them in the very places where a study of
Human Analysis would tell you to look for them.

Where to Look for Pure Types

When you wish to find some pure Alimentives, go to a restaurant that

When looking for the Osseous attend a convention of expert accountants,
bankers, lumbermen, hardware merchants or pioneers.

All these types appear in other places and in other vocations, but they
are certain to be present in large numbers any day in any of the
above-named places.

But when you are looking for this interesting little extreme
thinker-type you must go to a library. We specify the reference room of
the library because those who search for fiction, newspapers and
magazines are not necessarily of the pure type. And we specify a day in
summer rather than in winter so that you will be able to select your
subjects from amongst people who are there in spite of the weather
rather than because of it.

Interested in Everything

"I never saw a book without wanting to read it," said a Cerebral
friend to us the other day. This expresses the interest every person of
this type has in the printed page. "I never see a library without
wishing I had time to go there and stay till I had read everything in
it."

The Book Worm

So it is small wonder that such a one becomes known early in life as a
"book worm." As a little child he takes readily to reading and won't
take to much else. Because we all learn quickly what we like, he is soon
devouring books for older he
