The physician has a twofold duty to perform. He is called upon not merely to alleviate pain, and to undertake the cure of disease, but he is, moreover, required to lay down rules for the preservation of health, the prevention of disease, and its too frequent concomitant, pain.

Now, health being dependent upon the due and regular performance of the vital functions by the several physiological organs of the body, any excessive development of these organs, or undue manifestation of force on their part, must, of necessity, be contrary to the general health of the body, and be productive of disease and pain.

In many persons there exists a constitutional tendency to the excessive formation of blood, occasioning a plethoric condition, and thereby rendering the individual liable to a great many diseases; others again suffer from an exalted or diminished sensibility of the nervous system, inducing some of the greatest woes to which humanity is liable.

Many different elements are combined in the structure of the various organs of the body, and among these fat, in suitable proportion, must be recognized as necessary for the due and equable performance of the several organic functions.

This fat, however, often becomes excessive, giving rise at first to great inconvenience, after a time inducing debility, and finally constituting a disease (hitherto deemed incurable) termed obesity.

The possession of a graceful figure may be of little importance, in so far as the happiness of most men is concerned; but as regards the gentler sex, such is by no means the case. Women are too apt to believe that, in the absence of physical beauty, the possession of mental and worldly treasures can only suffice to render them endurable in their social relations. Beauty, the richest gift of nature, deserves to be carefully guarded by those who happily possess it; corpulence, its enemy, is destructive to the finest organization.

It is a painful sight to witness the many instances of women, who, though still of youthful years, and whose elegance of form, but a short time since, did but enhance their unsurpassed loveliness of countenance, lose by degrees, in the midst of an overwhelming fat, all this relative and graceful harmony, and whose ever increasing corpulence serves only to render them ill-favoured and repulsive. In all cases, so detrimental a change is much to be regretted; but for ladies mingling in the fashionable spheres of life, it is to be borne only when such a condition can be shewn to be utterly beyond all hope of relief.

Excessive corpulence has destroyed the prospects of many, both men and women, by rendering them incompetent to discharge the duties of a profession by which they had hitherto gained an honourable livelihood. Superabundance of fat prevents an infantry officer from following his regiment—a cavalry officer from being long on horseback; and thus both are alike compelled to retire from the service. The operatic artiste, whose voice or personal beauty had been hitherto a mine of wealth to the theatre, falls into indigence, because an excessive development of fat now embarrasses the lungs or destroys her personal charms.

Every one engaged in intellectual pursuits will say that since he has increased in fat he finds that he cannot work so easily as he did when he was thin. The painter feels the want of that vivid imagination which was wont to guide his brush. The sculptor labours with indifference upon the marble. The literary man feels heavy, and his ideas no longer flow in obedience to his will. The clerk in his office is ever complaining of the efforts he is obliged to make to resist an overwhelming drowsiness which interferes with his calculating powers, rendering him unable to compose a letter, or even to copy one. Obesity, in fact, lessens both physical and moral activity, and unfits man for the ordinary business of life.

It was in conformity with this opinion, no doubt, that the Romans at one time, wishing to have no drones among them, banished those of their fellow citizens who laboured under an excessive development of fat. One can conceive of the existence of such a law among a people who condemned to a like punishment any citizen known to be indifferent to the public welfare.
