d _bilious_, and
substitute one which is more characteristic.

We will not dwell upon the volitive as _psychical_ organs, except to
show that, when their influence is transmitted to the body, they act as
_physiological_ organs, and thus demonstrate that all parts of the brain
have their physiological, as well as mental functions. When Andrew
Jackson uttered with great emphasis the memorable words, "BY THE
ETERNAL," the effect was like a shock from a galvanic battery, thrilling
the cells in his own body, and paralyzing with fear every one in
Calhoun's organization. This is an illustration of the power or range of
action of these faculties. Breadth or copiousness is illustrated in Gen.
Grant's reply, "I PROPOSE TO FIGHT IT OUT ON THIS LINE, IF IT TAKES ALL
SUMMER." Such a temperament has a profusion of constitutional power,
great durability of the life-force, and, in our opinion, the combined
height and breadth of this region correctly indicate the natural
hardihood of the body and its _retentiveness of life_. No one need doubt
its influence upon the sympathetic system, and, through that system, its
power over absorption, circulation, assimilation, and secretion, as well
as the voluntary processes. Mental hardihood seems wrought into concrete
organization. It checks excess of glandular absorption, restrains the
impulses of tumultuous passion, tones and regulates the action of the
heart, and helps to weave the strands of organization into a more
compact fabric. The toning energies of the volitive faculties are better
than quinine to fortify the system against _miasma_ or _malaria_, and
they co-operate with all tonic remedies in sustaining organic action.
Fig. 91 is a portrait of Prof. Tyndall, the eminent chemist, whose
likeness indicates volitive innervation, showing great strength of
character and of constitution; he is an earnest, thorough, and intense
mental toiler; ambitious, but modest; brilliant, because persevering;
diligent in scientific inquiry, and who follows the star of truth,
whithersoever it may lead him. The expression of his countenance
indicates his honest intentions, and displays strength of conscientious
purpose; his physical constitution may be correctly interpreted in all
of its general characteristics by the analysis of his energetic
temperament, the great secret of his strength and success.
