retful, complaining,
irritable, dejected, morose, and, sooner or later, becomes a fit subject
for chronic disease.[5] The ultimate result of excessive fear,
excitability, and irritability, is functional or organic
derangement,--the morbid conditions represented by the word Disease. The
medulla oblongata and portions of the middle lobe of the brain, the
functions of which represent Excitability, Anxiety, Fear, and
Irritability (symbols of physical profligacy), are located just between
the ears (see Fig. 60). Inferior animals distinguished for breadth
between the ears are not only cunning and treacherous, but very
excitable and irritable. The head of the Fox is remarkable for its
extreme width at the region of Fear. He is proverbially crafty and
treacherous, always excitable, and so variable in temper that he can
never be trusted. He is a very timid thief, exceedingly suspicious,
irregular in habits, and frequently driven by hunger into mischievous
depredations.

The organ of alimentiveness, located directly in front of the ear,
indicates the functional conditions of the stomach, which, when aroused
by excessive hunger, exerts a debasing influence upon this and all of
the adjacent organs, and is demoralizing to both body and mind. In
obedience to the instinct of hunger, children will slyly plunder gardens
and orchards, displaying profligate, if not reckless tendencies in the
gratification of the appetite. In this regional division we include the
medulla, the posterior and middle portions of which give rise to the
pneumogastric nerve. This nerve receives branches from the spinal
accessory, facial, hypoglossal, and the anterior trunks of the first and
second cervical, and its filaments are distributed to the lungs,
stomach, liver, spleen, pancreas, and gall bladder (see Fig. 60, with
explanation) Its agency is necessary to maintain the circulation, and
the respiration, since, as the medium of communication, it conveys from
the brain large supplies of nervous force to sustain these vital
functions. It likewise instantly reports the impressions of these
physiological processes to the brain, and especially to those parts
which, by analogy of functions. It likewise instantly reports the
impressions of these physiological processes of the brain, and
especially to those parts which, by analogy of functions, are intimately
related to the stomach. Hence, we observe that the conditions of the
