The new artificial eye is nothing more than a plastic skullcap, set accurately upon the bulb of the diseased eye, so that it moves with the bulb as freely as the sound eye. The lids play freely over it; the lachrymal functions continue their healthy action; and the bulb is effectually protected from currents of cold air and particles of dust. But these effects can be gained only by modeling each artificial eye upon the particular bulb it is destined to cover; thus removing the manufacture of artificial eyes from the hands of clumsy mechanics, to the superintendence of the scientific artist. Every individual case, according to the condition of the bulb, requires an artificial eye of a different model from all previously made. In no two cases are the bulbs found in precisely the same condition; and, therefore, only the scientific workman, proceeding on well-grounded principles, can pretend to practice ocular prothesis with success. The newly-invented shell is of metallic enamel, which may be fitted like an outer cuticle to the bulb--the cornea of which is destroyed--and restores to the patient his natural appearance. The invention, however, will, we fear, increase our skepticism. We shall begin to look in people's eyes, as we have been accustomed to examine a luxuriant head of hair, when it suddenly shoots upon a surface hitherto remarkable only for a very straggling crop. Yet, it would be well to abate the spirit of sarcasm with which wigs and artificial teeth have been treated. Undoubtedly, it is more pleasant to owe one's hair to nature than to Truefit; to be indebted to natural causes for pearly teeth; and to have sparkling eyes with light in them. Every man and woman would rather have an aquiline nose than the most playful pug; no one would exchange eyes agreeing to turn in one direction, for the pertest squint; or legs observing something approaching to a straight line, for undecided legs, with contradictory bends. Hence dumb-bells, shoulder-boards, gymnastic exercises, the consumption of sugar steeped in Eau-de-Cologne (a French recipe for imparting brightness to the eyes), ingenious padding, kalydors, odontos, Columbian balms, bandolines, and a thousand other ingenious devices. Devices with an object, surely--that object, the production of a pleasing _personnel_. It is a wise policy to remove from sight the calamities which horrify or sadden; and, as far as possible, to cultivate all that pleases from its beauty or its grace. Therefore, let us shake our friend with the cork-leg by the hand, and, acknowledging that the imitation is worn in deference to our senses, receive it as a veritable flesh-and-blood limb; let us accept the wig of our unfortunate young companion, as the hair which he has lost; let us shut our eyes to the gold work that fastens the brilliantly white teeth of a young lady, whose natural dentition has been replaced; and, above all, let us never show, by sign or word, that the appearance of our friend (who has
