Are, then, particular portions of the brain larger or smaller in proportion as particular mental characteristics are stronger or weaker? Our short-hand answer is illustrated by the following anecdote. A Mr. Juror was once summoned to attend court, but died before its sitting. It therefore devolved upon Mr. Simple to state to the court the reason of his non-appearance. Accordingly, when Mr. Juror's name was called, Mr. Simple responded, "May it please the court, I have twenty-one reasons why Mr. Juror is not in attendance. The first is, he is DEAD. The second is--" "That ONE will answer," responded the judge. "One such reason is amply sufficient." But few of the many proofs that Phrenology is true will here be stated, yet those few are DECISIVE. First. THE BRAIN IS THE ORGAN OF THE MIND. This is assumed, because too universally admitted to require proof. Secondly. Is the brain, then, a SINGLE organ, or is it a bundle of organs? Does the WHOLE brain think, remember, love, hate, etc.; or does one portion reason, another worship, another love money, etc.? This is the determining point. To decide it affirmatively, establishes Phrenology; negatively, overthrows it. It is proved by the following facts. THE EXERCISE OF DIFFERENT FUNCTIONS SIMULTANEOUSLY.--We can walk, think, talk, remember, love, and many other things all TOGETHER,--the mind being, in this respect, like a stringed instrument, with several strings vibrating at a time, instead of like a flute which stops the preceding sound when it commences succeeding ones; whereas, if it were a single organ, it must stop thinking the instant it began to talk, could not love a friend and express that love at the same time, and could do but one thing at once. MONOMANIA.--Since mental derangement is caused only by cerebral disorder, if the brain were a single organ, the WHOLE mind must be sane or insane together; whereas most insane persons are deranged only on one or two points, a conclusive proof of the plurality of the brain and mental faculties. DIVERSITY OF TALENT, or the fact that some are remarkable for sense, but poor in memory, or the reverse; some forgetting names, but remembering faces; some great mechanics, but poor speakers, or the reverse; others splendid natural singers, but no mechanics, etc., etc., conducts us to a similar conclusion. INJURIES OF THE BRAIN furnish still more demonstrative proof. If Phrenology be true, to wound and inflame Tune, for example, would create a singing disposition; Veneration, a praying desire; Cautiousness, groundless fears; and so of all the other organs. And thus it is. Nor can this class of facts be evaded. They abound in all phrenological works, especially periodicals, and drive and clench the nail of proof.
