physical force.

Each had a large brain. In Dr. Wm. Byrd Powell, who had a
long head, and who was a man of restless ambition and fiery
energy, the occipital predominated over the frontal
development decidedly, producing, although the frontal
development was not large, much activity and force, or
brilliancy of mind, but not the calm temperament most
favorable to philosophy. His opinions were more bold and
striking than accurate. Dr. P. made a valuable collection of
crania, and was almost the only American scientist who gave
much attention to the _cultivation_ of phrenology.

From these remarks the reader will understand that force belongs to
the occiput and gentleness to the front. The occipital region is
associated with the spinal column and the limbs, in which regions the
vital forces reside. Hence the occipital action of the brain generates
vital force and diffuses it in the body, while the frontal region, in
its aggregate tendency, expends the vital force--the greatest tendency
to expenditure being in the most extreme frontal region. Both the
front lobe and the anterior extremity of the middle lobe tend to the
expenditure of vital force and destruction of health, and it is
absolutely necessary to life that the action of the front lobe should
be suspended one-third of our time by sleep, without which it would
exhaust vitality.

We shall therefore find that organs are located farther backward in
proportion to the energy and impelling power of the faculty, and farther
forward in proportion to their delicacy and intellectuality--the
extreme front being the region of maximum intelligence.

With these two rules, giving the latitude by the ethical quality and
the longitude by the active energy, I have been accustomed to require
my pupils to determine the location of the various elements of human
nature, bearing in mind that organs of analogous functions are located
near together, and organs of opposite or antagonistic functions occupy
opposite locations in the brain; and thus in proportion as one is
above the horizontal line the other is below it, and in proportion as
one is forward the other is backward,--in proportion as one is
interior or near the median line, the other is exterior or toward the
lateral surface.

With this introductory explanation, I begin by asking, Where should we
locate the faculty which has the maximum degree
