This is just what no automaton can do. Many of our readers have, however, seen a young lady in the shop-windows, or entertained her in their own nurseries, who professes to be this hitherto impossible walking automaton, and who calls herself by the Homeric-sounding epithet Autoperipatetikos. The golden-booted legs of this young lady remind us of Miss Kilmansegg, while their size assures us that she is not in any way related to Cinderella. On being wound up, as if she were a piece of machinery, and placed on a level surface, she proceeds to toddle off, taking very short steps like a child, holding herself very stiff and straight, with a little lifting at each step, and all this with a mighty inward whirring and buzzing of the enginery which constitutes her muscular system.
An autopsy of one of her family who fell into our hands reveals the secret springs of her action. Wishing to spare her as a member of the defenceless sex, it pains us to say, that, ingenious as her counterfeit walking is, she is an impostor. Worse than this,—with all our reverence for her brazen crinoline, duty compels us to reveal a fact concerning her which will shock the feelings of those who have watched the stately rigidity of decorum with which she moves in the presence of admiring multitudes. She is a quadruped!. Inside of her great golden boots, which represent one pair of feet, is another smaller pair, which move freely through these hollow casings.

Four cams or eccentric wheels impart motion to her four supports, by which she is carried forward, always resting on two of them,—the boot of one side, and the foot of the other. Her movement, then, is not walking; it is not skating, which it seems to resemble; it is more like that of a person walking with two crutches besides his two legs. The machinery is simple enough: a strong spiral spring, three or four cog-wheels and pinions, a fly to regulate the motion as in a musical box, and the cams before mentioned. As a toy, it or she is very taking to grown people as well as children. It is a literal fact, that the police requested one of our dealers to remove Miss Autoperipatetikos from his window, because the crowd she drew obstructed the sidewalk.
We see by our analysis of the process, and by the difficulty of imitating it, that walking is a much more delicate, perilous, complicated operation than we should suppose, and well worth studying in a practical point of view, to see what can be done to make it easier and safer. Two Americans have applied themselves to this task: one laboring for those who possess their lower limbs and want to use them to advantage, the other for such as have had the misfortune to lose one or both of them.
Dr. J.C. Plumer, formerly of Portland, now of Boston, has devoted himself to the study of the foot, and to the construction of a last upon which a boot or shoe can be moulded which shall be adapted to its form and accommodated to its action.
Most persons know something of the cruel injustice to which the feet are subjected, and the extraordinary distortions and diseases to which they are liable in consequence. The foot's fingers are the slaves in the republic of the body. Their black leathern integument is only the mask of their servile condition. They bear the burdens, while the hands, their white masters, handle the money and wear the rings. They are crowded promiscuously in narrow prisons, while each of the hand's fingers claims its separate apartment, leading from the antechamber, in the dainty glove. As a natural consequence of all this, their faculties are cramped, they grow into ignoble shapes, they become callous by long abuse, and all their natural gifts are crushed and trodden out of them.
Dr. Plumer is the Garrison of these oppressed members of the body corporeal. He comes to break their chains, to lift their bowed figures, to strengthen their weakness, to restore them to the dignity of digits. To do this, he begins where every sensible man would, by contemplating the natural foot as it appears in infancy, unspoiled as yet by social corruptions, in adults fortunate enough to have escaped these destructive influences, in the grim skeleton aspect divested of its outward disguises. We will give the reader two views of the latter kind, illustrating the longitudinal and transverse arches before spoken of.

A man who walks on natural surfaces, with his feet unprotected by any artificial defences, calls the action of these arches into full play at every step. The longitudinal arch is the most strikingly marked of the two. In some races and in certain individuals it is much developed, so as to give the high instep which is prized as an evidence of good blood. The Arab says that a stream of water can flow under his foot without touching its sole. Under the conditions supposed, of a naked foot on a natural surface, the arches of the foot will commonly maintain their integrity, and give the noble savage or the barefooted Scotch lassie the elasticity of gait which we admire in the children of Nature.
