"'Tis the great art of life to manage well
The restless mind."

In the course of this vitally important and deeply-interesting subject of inquiry, it is not my intention to enter into any metaphysical discussion respecting the inscrutable and mysterious union existing between matter and mind, or to endeavour to point out the manner in which the body influences the mind, and the mind the body. Such subjects we do not think to be legitimate objects of inquiry. The medical philosopher is engaged in less obscure and less uncertain researches; he does not attempt to solve the question regarding the intimate union subsisting between the natural and intellectual portions of our nature, but he wisely confines himself to an attentive examination of the phenomena which result from that union. Man is compounded of a soul and body, so closely united, not identified, that they frequently struggle and occasionally overpower each other. Sometimes the mind ascends the throne and subdues, in a moment, the physical energies of the most powerful of her subjects. At other times the body gains the ascendency, and lays prostrate before her the mightiest of human intellects. Instances illustrative of both propositions are of daily occurrence. It has been said of Sophocles, that being desirous of proving that at an advanced age he was in full possession of his intellectual faculties, he composed a tragedy, was crowned, and died through joy. The same thing happened to Philippides, the comic writer. M. Juventius Thalma, on being told that a triumph had been decreed to him for having subdued Corsica, fell down dead before the altar at which he was offering up his thanksgiving. Zimmerman, in his work on Experience in Physic, has related the circumstance of a worthy family in Holland being reduced to indigence; the elder brother passed over to the East Indies, acquired considerable fortune there, and returning home presented his sister with the richest jewel: the young woman, at this unexpected change of fortune became motionless and died. The famous Forquet died on being told that Louis XIV. had restored him to his liberty. It is also related of Diodorus Chronos, who was considered as the most subtle logician of the time of Ptolemy Soter, that Stilbo one day in the presence of the king, proposed a question to him, to which he was unable to reply. The king, willing to cover him with shame, pronounced only one part of his name, and called him ovos, ass, instead of Chronos. Diodorus was so much affected at this as to die soon afterwards.

Perhaps there is not a more remarkable instance on record showing, in a melancholy though forcible light, the dominion of mind over the material frame, than the circumstances which attended the death of John Hunter. This distinguished surgeon and physiologist died in a fit of enraged passion; and, what is somewhat extraordinary, he had often predicted that such excitement would prove fatal to him. He died at St. George's Hospital, Oct. 16, 1793, under these circumstances: being there in the exercise of his official duty as surgeon, he had a warm dispute with Dr. Pearson, on a professional subject; upon which he said, "I must retire, for I feel an agitation which will be fatal to me if I increase it." He immediately withdrew into an adjoining room; but Dr. Pearson, not being willing to give up his argument, followed him, which so annoyed Hunter, that he vehemently exclaimed, "You have followed me on purpose to be the death of me! You have murdered me!" and instantly fell and expired! Mrs. Byron, the mother of the noble bard, is said to have died in a fit of passion. Mr. Moore, in his life of Lord Byron, in speaking of Mrs. Byron's illness, says,—"At the end of July her illness took a new and fatal turn; and so sadly characteristic was the close of the poor lady's life, that a fit of ague, brought on, it is said, by reading the upholsterer's bills, was the ultimate cause of her death." A somewhat similar circumstance is recorded of Malbranche. The only interview that Bishop Berkley and Malbranche had was in the latter philosopher's cell, when the conversation turned upon the non-existence of matter, and Malbranche is said to have exerted himself so much in the discussion that he died in consequence. Sanctorius relates an instance of a famous orator, who so far exerted his mind in delivering an oration that he became, in a few hours, quite insane.

The effect of a too close application of mind to study on the bodily health has long been a matter of common observation. The Roman orator, Cicero, points out forcibly the dangers arising from inordinate exertion of mind; and he has laid down some rules for guarding against the effects of study. M. Van Swieten, in alluding to this subject, relates the case of a man whose health was severely injured, by what he calls "literary watchings." Whenever he listened with any attention to any story, or trifling tale, he was seized with giddiness; he was in violent agonies whenever he wanted to recollect any thing which had slipped his memory; he oftentimes fainted away gradually, and experienced a disagreeable sensation of lassitude. Rousseau has very justly remarked, that excessive application of mind "makes men tender, weakens their constitutions, and when once the body has lost its powers, those of the soul are not easily preserved. Application wears out the machine, exhausts the spirits, destroys the strength, enervates the mind, makes us pusillanimous, unable either to bear fatigue, or to keep our passions under."[3 - Preface de Narcisse Oeuvres, Diverses, t. l. v. 172.]

Shakspeare appears to have formed a just conception of the great injury which the corporeal frame experiences from a too close application of mind. The immortal bard observes,—

"–Universal plodding poisons up
The nimble spirits in the arteries
As motion and long-during action tires
The sinewy vigour of the traveller."

    Love's Labour Lost.
In the consultations of Wesper we find related the history of a young man of family 22 years of age, who, having applied himself incessantly to intense mental exertion, was seized with a fit of insanity, in which fit he wounded several persons and killed his keeper. Catalepsy has been known to have been produced by great mental application. Fomelius gives us a remarkable instance of it. A man (says he) who passed whole nights in writing and studying, was suddenly attacked with a fit of catalepsy: all his limbs stiffened in the attitude he was in when the disease first seized him. He remained upon his seat, holding the pen in his hand, and with his eyes fixed on his paper, so that he was considered to be still at his studies, till being called to, and then shaken, he was found to be without motion or sensation.[4 - Pathol. lib. 3. cap. 2. Oper. Omm. p. 406.]

Many extraordinary instances are on record, of remarkable changes having been produced in birds by an affection of the animal passions. The following fact is related by Mr. Young, in the Edinburgh Geographical Journal. A blackbird had been frightened in her cage by a cat; when it was relieved, it was found lying on its back, quite wet with perspiration. The feathers fell off, and were renewed, but the new ones were perfectly white.

A similar phenomenon has been observed in the human species, who have been exposed to the effects of inordinate passion. Borrelli relates the case of a French gentleman, who was thrown into prison, and on whom fear operated so powerfully as to change his hair completely grey in the course of one night. Dr. Darwin ascribes this phenomenon to the torpor of the vessels, which circulates the fluids destined to nourish the hair. Nothing will, perhaps, demonstrate more fully the effects of moral causes in producing disease than the structural alterations discoverable in the bodies of those who have died whilst labouring under nostalgia, or the Swiss malady. This disease is considered peculiar to the Swiss, and is occasioned by a desire of revisiting their own country, and of witnessing again the scenes of their youth. This desire begins with melancholy sadness, love of solitude, silence, bodily weakness, &c. and is only cured by returning to their native country. Avenbrugger says, that in dissecting the bodies of those who have died in consequence of this disease, organic lesions of the heart generally are detected. A particular musical composition, supposed to be expressive of the happiness of the people, is in great vogue in Switzerland. If this tune or piece of music is played among the Swiss in any foreign country, it tends strongly to recall their affections for their native soil, and their desire of returning, and to induce the desire called nostalgia consequent on their disappointment. The effects of this musical composition is so powerful, that it is forbidden to be repeated in the French camp on pain of death, it having at one period had the effect of producing a mutiny among the Swiss soldiers, at that time in the employ of the French king.

Predictions of death, whether supposed to be supernatural, or emanating from human authority, have often, in consequence of the poisonous effects of fear, been punctually fulfilled. The anecdote is well attested, of the licentious Lord Littleton, that he expired at the exact stroke of the clock, which in a dream or vision, he had been forewarned would be the signal of his departure. In Lesanky's voyage round the world, there is an account of a religious sect in the Sandwich Islands, who arrogate to themselves the power of praying people to death. Whoever incurs their displeasure, receives notice that the homicide litany is about to begin, and such are the effects of the imagination, that the very notice is frequently sufficient with these people to produce the effect.
