The new method is to prepare a mixture of sugar and water, and sawdust—it may be of any other substance containing saccharine matter, such as beetroot, potatoes, turneps, honey, &c. The action of the sugar and pyroxalic, or wood spirit, is so rapid, that the skins are rendered fit to receive and imbibe the tannic acid; and thus the operation of tanning is perfectly accomplished in a very short time. The leather thus produced is considerably heavier, and of finer quality, than any leather produced by the present method of tanning. This method of removing the lime is of immense importance, as it not only improves the leather in weight and durability, but enables the tanner to produce a superior article in a much less space of time, and at a much less expense, than heretofore. Attempts have been made to remove the lime by a preparation called grainer, which is mainly composed of the dung of animals. This being of a strong alkaline nature, necessarily destroys a considerable portion of the gelatinous matter, in the operation of extracting the lime; at the same time much injury is done to the texture of the skin by its rapid action in causing decomposition, and destroying the grain side of the skin, especially in summer. It must be obvious, however, that the moment the skin imbibes lime in any quantity, its effect and influence on the hide or skin are to a considerable extent permanent and destructive.
The advantages of the new method appear to be, first, a great additional weight of leather, especially in calfskins; second, leather of much better quality, soft and not liable to crack or strain; third, a considerable diminution in the expense; and fourth, the tanning is effected in one quarter of the time consumed by the present mode of tanning.
These improvements will, it is needless to say, prove of immense importance to our home manufacture, and now that the true principles of tanning skins comes to be understood, many other improvements will gradually suggest themselves. The Rouel leather, which is the name given to it by the doctor, is certainly the best article ever produced in England (I speak now of calfskin), and works up as fine or even finer than the French, without its accompaniment of dubbing, or its impost of 30 per cent.
In Queen Elizabeth’s time, parliament busied itself much in matters of “leather and prunella;” numerous enactments being made, especially in reference to the former. A letter to lord-treasurer Burleigh, by W. Fleetwood, recorder of London, explains the opposition of the tanners to some enactments against them: “the one for lymyng [an old grievance, after all, this lymyng], the other raisyng.” He says: “All the excellencie and conning of a tanner consisteth in skilfull making of his owes [lyes;] surelie they must be many and severall and one stronger than another. The time of changing of the lether from one owes must be timed at proscribed hours, or else the lether will be utterly spoiled. My Lo, there be an infinite number of rules to be observed in tanning, the few which tanners did ever conceive, much less the parliament, who conveyed their information of such whome nowe I do by experiens knowe not to be skilfull.” A conclusion which many of good Queen Victoria’s as well as Queen Bess’s subject have arrived at, after parliamentary evidence and enactment, in matters which history, experience, and philosophy, have long since taught us, flourish best by being let alone.
CHAPTER V.
THE STRUCTURE OF THE HUMAN FEET, ETC.
“There is nothing more beautiful than the structure of the human foot,” says Sir Charles Bell; “nor perhaps any demonstration which would lead a well-educated person to desire to know more of anatomy than that of the foot. The foot has in its structure all the fine appliances you see in a building. In the first place, there is an arch, in whatever way you regard the foot; looking down upon it, we perceive several bones coming round the astralagos, and forming an entire circle of surfaces in the contact. If we look at the profile of the foot, an arch is still manifest, of which the posterior part is formed by the heel, and the anterior by the ball of the great toe; and in the front, we find in that direction a transverse arch: so that, instead of standing, as might be imagined, on a solid bone, we stand upon an arch composed of a series of bones, which are united by the most curious provision for the elasticity of the foot; hence, if we jump from height directly upon the heel, a severe shock is felt; not so, if we alight upon the ball of the great toe, for there an elasticity is formed in the whole foot, and the weight of the body is thrown upon this arch, and the shock avoided.”
Another writer, on the “diseases of the feet,” thus alludes to the beauty and perfection of the human foot in its natural state:—
“The matchless forms of sculptured beauty which the destroying hand of time has left us in the works of the mighty masters of the classic time, exhibit to us the finest specimens of what the foot would be, if allowed its free and uninterrupted action.
“We are immediately struck with the admirable manner in which it is organized, both for the support of the frame and for motion; its flexibility, its power of action, its form, seem all to have been the result of the examination of the most perfect human models. We see that there have been no artificial coverings, no compression, no restraints; that the gait must have been free, firm, and elastic; that the natural and healthful action of every muscle, tendon, joint, and bone, was fully studied and expressed. There is no stiffness, no contraction of the heel or the sole of the foot; to the toes are given their proper functions; we see that only the sandal has been worn, merely to cover and protect the integument under the broad and expanded foot, there have been no ligatures, no unyielding bandages, no cramping compresses—all is alike free, healthful, natural.
“We well can comprehend, on examining them, how the Macedonian phalanx or the Roman legion, performed its long day’s march. We can see how ten thousand Greeks pursued their daily wearying course through the destroying climate of Asia, marching firmly, manfully, alike across the arid sand, the mountain pass, or the flinty plain.
