"Tempora Mutantur."

The present is emphatically the age of useful invention and scientific discovery; and it is the peculiar good fortune of the present generation, that the indefatigable labors of a few gigantic minds have opened to it new and expanded sources of enjoyment, by the development of principles which have long eluded the grasp of philosophy, and by their practical application to the most ordinary affairs of life. Men are not now bewildered by the imposing mysteries in which scientific truth has been so long enveloped; nor are they deterred from a bold investigation into the solidity of theories and hypotheses, by the studied ambiguity of phrase in which the votaries of learning have veiled them. They have learned properly to appreciate the fallacy of those abstruse speculations and metaphysical researches, into which so many thousands, in pursuit of some vain chimera, have been inextricably involved—and have erected the standard of utility as that alone by which all the lucubrations of moonstruck enthusiasts, and all the experiments of visionary projectors are to be rigidly scanned and tested. The practical benefits which have resulted from the rapid march of mind, are to be seen in the application of steam to the propulsion of boats, and in the innumerable rail roads, canals, and other stupendous improvements, which have developed the resources of this extensive country, and multiplied the blessings so bounteously bestowed upon it by providence. But in the first glow of astonishment and exultation which these have excited in the minds of men, numerous beneficial changes of minor importance have followed the march of intellect, which from their comparative insignificance, have almost escaped observation.

Formerly, the professors of the complex sciences of law, medicine, and divinity, were regarded as exalted by their attainments, to an immeasurable height of superiority over the mass of mankind, because they shrouded the truths and principles of science from the vulgar eye, by a veil of unintelligible jargon and grandiloquent technicalities, entirely above the ordinary powers of comprehension. Years of laborious and incessant toil were requisite to master the hidden complexities of those venerated and "time-honored" professions; and he, who with martyr-like resolution and unwearied perseverance, devoted his time and talents to their attainment, was regarded by the "vulgus ignobile" with sentiments of respect and admiration, nearly approaching to the idolatrous reverence of a Hindoo, for the fabled virtues of his bloody Juggernaut. But the illusion has at last been dispelled by the refulgent light of truth, and those illustrious individuals, the Luthers of the age, who have stripped these hoary errors of the veil which concealed their enormity, may with merited exultation and triumph exclaim, "Nous avons changé toute cela!" The art of economising time has been simplified, and subjected to the grasp of the most obtuse intellect; so that a science which formerly required years of intense and unremitted study, united with long experience and observation, is now thoroughly understood and mastered in a fortnight! So rapid indeed has been the march of intellect, sweeping from its path obstacles heretofore deemed insurmountable, and scaling the most impregnable fortifications of philosophy, with a force no less astonishing than irresistible, that many of our most profound adepts in the "glorious science" of the law, are (mirabile dictu!) at once initiated into all its mysteries by a single perusal of "Blackstone's Commentaries" and the "Revised Code!" instead of toiling his way up the steep ascent of fame by consuming the midnight oil, by exploring the dark and forbidding chambers of the temple of law, dragging forth truth from the musty volumes of antiquity, and searching the origin of long established principles. Among the feudal customs of our Saxon progenitors, a man may now become "like Mansfield wise, and Old Forster just," by one month's attendance at the bar of a county court! At the expiration of that period, he can rivet an admiring audience in fixed attention, by the strains of Demosthenian eloquence, in which he asks if "the court will hear a motion on a delivery bond?" And will astound some illiterate ignoramus, by the consequential pomposity with which he prates of "contingent remainders," "executory devises," and all the labyrinthian subtleties of nisi prius! No one will then contest his right to perambulate the streets, with all the ostentatious dignity of a man "learned in the law," and to parade before the eyes of the admiring rabble, his colored bag of most formidable dimensions,—albeit, it may be filled with cheese and crackers to stay his stomach in the intervals of business.

But the inappreciable benefits which the "March of Intellect" has showered upon mankind, are easily discovered by referring to the stupendous revolutions it has achieved, not only in the science of law but in divinity, medicine, education, manners, and morals. Men do not now venerate the ancient fathers of the church for the profound erudition and wonderful acquirements displayed in those ponderous tomes which now and then greet the eyes of the bibliopole, exciting the same degree of astonishment as the appearance of a comet illumining the immensity of space with its brilliant scintillations, or some lusus naturæ like the Siamese twins. Far from it. Modern philosophers have discovered the inutility and absurdity of wading through the voluminous discussions of controversial theologists, and tracing the origin of some religious dogma or doctrinal schism, which has for ages furnished these pugnacious wiseacres with food for inquiry and research. Instead of wasting the time necessarily consumed in these ridiculous studies, men who formerly might have dragged out their lives in the vulgar vocation of a tailor, a butcher, or a hatter, spring forth in a single week armed cap-a-pie to defend their religion from the unhallowed assaults of infidels, and amply qualified to expound the sacred texts, and deal out damnation with the indiscriminate prodigality of a spendthrift, for the first time cursed with the means of gratifying his extravagant propensities.

Formerly too, the most attentive and patient observation of the progressive development of the mental faculties of a child were necessary to enable a parent to adapt his education to the sphere of life in which nature had destined him to move. Innumerable obstacles were to be encountered in tutoring his mind to the comprehension of the profession for which he was intended; and, perhaps, after years of incessant toil and intense parental anxiety, the young stripling blasted all the hopes of his kindred, by either becoming the hero of a racefield or the magnus apollo of a grog shop, or distinguished his manhood by the puerile follies of youth, or the incurable stupidity of an idiot. But the "March of Mind" has obviated or removed all these difficulties, by the discovery of the renowned science of phrenology. A parent, in this blessed age of intellectual illuminism, may by an examination of certain craniological protuberances, ascertain with mathematical exactness, whether his child is a hero or a coward, a philosopher or a—fool; and may regulate his education in conformity to the result. The safety and well being of society, too, is thus encompassed with additional safeguards, which will effectually protect it from those evils which have heretofore been only partially suppressed by legislation. If any ill favored monster of the human species happens to have the organ of destructiveness largely "developed," (ut verbum est) and not counteracted by any antagonist organ,—all the murders, rapes and thefts which he is morally certain to perpetrate,—with their attendant train of want, calamity and ruin, may be at once prevented by hanging the scoundrel in terrorem, as a kind of scarecrow to all evil doers. A desideratum in political economy will thus be also attained. The accounts of those "caterpillars of the commonwealth," clerks, sheriffs, lawyers, et id omne genus, who swarm around the treasury in verification of the old maxim of Plautus, "ubi mel, ibi apes,"—(Anglice—Where there is money, there are lawyers,) are balanced without the payment of a cent; for it is obvious that there is no necessity for all the tedious formalities of a trial at law, the guilt of the murderer being already ascertained and summarily punished by this preventive justice, and the commonwealth of course exempted from the expense of a prosecution.

It would require a volume to enumerate all the advantages which have resulted from the discovery of this science. But even these are about to be quadrupled by the successful experiments recently made in the immortal and euphoniously titled science of phrenodontology, by which a man's grinders are regarded as the unerring indices of his habits, manners and propensities; and should these last be of an evil nature, they can be entirely eradicated by the extraction of such of the incissores as indicate their existence. There is no necessity whatever of inculcating self denial, regular habits, fortitude and virtue, to correct the depravity and vice of any individual. Only knock out his teeth, (or as that method is somewhat too summary,) have them extracted secundum artem by a dentist, and you instantly metamorphose him into a paragon of moral purity!

But one of the principal benefits of the "March of Mind," is the salutary reformation effected in the opinions of mankind, in relation to numerous important subjects. All those low and grovelling ideas which once tenanted the crania of our honest yeomanry as to the education of their children, have now evaporated into thin air. Instead of tying their sons to a vulgar plough, bronzing their visages to the complexion of an Indian, as was formerly the absurd practice, they are now transplanted into the genial hothouse of a town life, where they are soon installed in all the fashionable paraphernalia of tights, dickey, and safety chain; and astonish their honest old dads by the dexterity with which they flourish a yardstick, and by the surprising volubility with which they can chatter nonsense, a la mode du bon ton. I have often been enraptured with the incontrovertible evidence of the "March of Mind," when I saw one of these praiseworthy youngsters, with his crural appendages, cased in a pair of eelskin inexpressibles, and his nasal adjunct inflamed to that rubicund complexion which Shakspeare has immortalized in the jovial Bardolph, quiz a country greenhorn, and cul, in the genuine Brummel style, some vulgar, lowborn, mechanic acquaintance, who insolently aspired to the honor of a nod! The improvement too, in the education of our young ladies, is "confirmation strong as proof of holy writ," of the rapid and resistless march of science and intellect. With a precocity of talent which would have absolutely dumbfoundered a belle of the olden time, they now arrive at full maturity at the age of thirteen; when

"My dukedom to a beggarly denier,"

they can out-manoeuvre the most consummate coquette of fifty! They perfect their education with almost the rapidity of light; and prattle most bewitchingly in French or Italian, before their pretty mouths have been sullied by their vulgar vernacular. The odious and despicable practice of knitting stockings and baking pies, fit only for a race of Goths in an age of Vandalism, has been inscribed with "Ilium fuit," and is now patronised only by the rustic canaille, who still adhere to the horrid custom of rising at the dawn of day and attending to household business. Their proficiency too, in the science of diacousticks, or the doctrine of sounds, is truly amazing—and the whole posse comitatus of foreign fiddlers, jugglers, and mountebanks who kindly condescend to instruct them in music, (as they facetiously term it) are often thrown into raptures by the ease with which they produce every variety of noise on a piano, from the deafening roar of a northwester to the objurgatory grunt of a Virginia porker, unceremoniously ousted from his luxurious ottoman of mud!

But, as Byron says, greater "than this, than these, than all," are the wonderful phenomena which have occurred in the science of medicine. The physicians of modern times, have snatched the imperishable laurels from the brows of Galen and Hippocrates, and have compelled Old Esculapius himself, to "hide his diminished head!" It had long been a source of the most poignant regret to the philanthropic observer of the ills and afflictions incident to human nature, that the benign system of medical jurisprudence, designed originally for the alleviation of human suffering, had been so dilatory and uncertain in its operation, and so fatally ill adapted to the eradication of numerous diseases from the human frame, as to effect only a partial accomplishment of its beneficent purpose. This radical disadvantage in that system of medical science, might reasonably have been attributed to the want of a proper firmness and adventurous temerity in its practitioners;—probably, also, it might have resulted from their lamentable ignorance of the structure and conformation of the human frame. This system, as was to have been expected, had met with numerous advocates, principally in consequence of their perfect personal indemnity from the frequently fatal result of their ignorance or mismanagement; it being well known that under this system a practitioner might, if he so chose, administer a deadly poison to his patient, who would naturally "shuffle off this mortal coil," while his afflicted relatives would piously attribute his decease to a dispensation of Providence; and the physician, composedly pocketing his fees, would have the satisfaction of seeing himself eulogised in his patient's obituary, as a man of "science and skill." It is obvious that under this system the patient's life was but
