Medical Jurisprudence (Complete‪)‬

Medical Jurisprudence may be defined, a science by which medicine, and its collateral branches, are made subservient to the construction, elucidation, and administration of the laws; and to the preservation of the public health.

It accordingly resolves itself into two great divisions—into Forensic Medicine, comprehending the evidence and opinions necessary to be delivered in courts of justice; and into Medical Police, embracing the consideration of the policy and efficiency of legal enactments for the purpose of preserving the general health, and physical welfare of the community.

Under no circumstances does medical science assume so imposing and dignified an attitude, as when regarded as a branch of legislation. Disentangled from the web with which worldly caprice, credulity, and empiricism, are ever seeking to embarrass the more ordinary path of her labours, she at once displays her pride and strength in the number and variety of her resources, and in the extent and importance of their applications; while the professor of our art is thus enabled to support additional claims upon the respect of the learned, the confidence of the oppressed, and the gratitude of the public. In the active exercise of his duties as a medical jurist, how exalted and honourable is the occupation of the physician!—there is scarcely a circle of natural science, upon the boundaries of which he does not impinge in some point or other, of his extensive orbit. Trace his progress, for instance, through the subject of poisons, and we shall soon perceive that it involves within its range the departments of anatomy, physiology, botany, mineralogy, zoology, and chemistry. If, again, we follow his steps through the deviating and perplexing course of homicide, in how many new and interesting forms will the principles of physiology present themselves; how frequently shall we find ourselves engaged in the solution of problems connected with the knowledge of pneumatics, hydrostatics, and mechanics? If we attend him in the investigation of nuisances, as affecting the health and comfort of the surrounding inhabitants, we shall perceive that an acquaintance with the various branches of natural philosophy, can alone enable him to appreciate the nature and extent of the evil, or the value of the different plans that may be proposed for its removal. While the intricate and perplexing subjects of quarantine and plague police, will require for their elucidation, the energies of a peculiarly constructed and well disciplined mind, to concentrate the genuine lights into a focus, and to dissipate the many specious, but false appearances, with which the question of contagion has been distorted.

The institution of medicine and jurisprudence, necessarily arose as the consequence of the physical and moral infirmities of our nature, and must, therefore, have been nearly coeval with the origin of society. In the earlier periods, however, of the world, the connection between these sciences could only have been slight, and scarcely, perhaps, perceptible; although we are strongly inclined to believe that Medical Jurisprudence has an origin far more ancient, and an influence far more extensive, than modern writers have been willing to concede; an opinion which we are prepared to support by the authorities of profane as well as sacred writers, and by the history of civilized as well as barbarous communities. It must be admitted, that no inconsiderable a part of the institutions of the great law-giver of Israel, was a wise system of medical police, well adapted for the preservation of the health, and the amelioration of those evils to which the inhabitants of a tropical climate must have been exposed; and we read, that Moses was skilled in all the learning of the Egyptians. In Leviticus, commands are given to the priests to visit the houses infected with the plague of leprosy, or with any contagious disease; to examine the inhabitants; to establish quarantine; to scrape and white-wash the houses; to shut them up, and, in bad cases, to pull them down. If we descend into later times, we shall discover the same policy of associating the institutions of medical police with religious ceremonials; by which the performance of duties, essential to the preservation of the health, was more effectually enforced. The author has observed, in the historical introduction of his “Pharmacologia,” that bathing, which at one period of the world was essentially necessary to prevent the diffusion of leprosy, and other infectious diseases, was wisely converted into an act of religion, and the priests persuaded the people that they could only obtain absolution by washing away their sins by frequent ablution; but, since the use of linen shirts has become general, and every one has provided for the cleanliness of his own person, the frequent bath ceases to be so essential; and, therefore, no evil has arisen from the change of religious belief respecting its connection with the welfare and purity of the soul. Among the religious impurities, and rules of purification of the Hindus, we shall be able to discern the same principle, although distorted by superstition. So, again, it is easy to perceive, that the dangers consequent upon vinous inebriation in a hot climate, suggested the Mahometan prohibition of wine. The religious ceremonial observed by the ancients, whenever they proposed to build a town, or to pitch a camp, was evidently an act of legislation, founded on a just principle of physiology; they offered a sacrifice to the gods, when the Soothsayer declared, from the appearance of the entrails, whether they were propitious or not to the design. What was such an inspection but a philosophical inquiry into the salubrity of the district, and the purity of the waters by which it was supplied?—for it is well known that in unwholesome situations, especially if swampy, the viscera of the cattle will universally present an appearance of disease, which an eye experienced in such dissections, would easily distinguish.
