To show the facility with which organs may be located upon general principles, I present herewith the locations actually made by a small class of pupils when I first proposed to have them determine locations according to the general laws of organology. None of these locations would be called erroneous, the most incorrect of all being Adhesiveness, located a little too high. They are Be. Benevolence, Ac. Acquisitiveness, Phi. Philanthropy, Des. Destructiveness, Lo. Love, Ha. Hate, Hu. Humor, Mod. Modesty, Os. Ostentation, Con. Conscientiousness, Ba. Baseness, Pa. Patience, Irr. Irritability, For. Fortitude, Al. Alimentiveness, Her. Heroism, Sen. Sensibility, Hea. Health, Dis. Disease, Ad. Adhesiveness, Co. Combativeness, Ar. Arrogance, Rev. Reverence, Ca. Cautiousness, Ra. Rashness. The suggestion cannot be too often repeated that the nomenclature of cerebral organology can never adequately express the functions of the organs. The brain has in all its organs physiological and psychic powers, which no one word can ever express fully. Sometimes a good psychic term, such as Firmness, suggests to the intelligent mind a corresponding influence on the physiological constitution, but in the present state of mental science the conception of such a correspondence is very vague. Moreover, even the psychic functions are not adequately represented by the words already coined in the English language for other purposes, and I do not think it expedient at present to coin new terms which would embarrass the student. The word Sanity, for example, answers its purpose by signifying a mental condition so firm and substantial as to defy the depressing and disturbing influences that derange the mind. It produces not the mere negative state, or absence of insanity, but a positive firmness, and self-control, which is the interior expression of firmness. The cheerful, stable, manly, and well-regulated character which it produces, disciplines alike the intellect and the emotions, and shows itself in children by an early maturity of character and deportment, and freedom from childish folly and passion. If a new word should be introduced to express this function, the Greek word SOPHROSYNE would be a very good one, as it signifies a self-controlled and reasonable nature. The verb ANDRISO, signifying to render hardy, manly, strong, to display vigor, and make a manly effort of self-control, would be equally appropriate in the adjective form, ANDRIKOS, and still more in the noun ANDRIA, which signifies manhood or manly sentiments and conduct. It would not, however, be preferable to the English word, MANLINESS, which is as appropriate a term as Sanity or ANDRIA. TO YOU PERSONALLY.
