That part of the foot extending from the line of separation on one side, to the corresponding line of separation on the other, having the FROG in the center, and marked 2 on each side, is called the _outer sole_, covering a membranous mass, or substance, called the _inner sole_, which is of exquisite sensibility, requiring PROTECTION without _pressure_ upon the external part; which it will be seen (by referring to the PLATE) is sufficiently afforded by the concave formation at Fig. 6 of letter E, which, upon the accurate inspection of the best informed and most experienced investigators, must be admitted a shoe of the first perfection for the promotion of every good, and the prevention of every ill. Having thus produced both _foot_ and _shoe_, as unsullied representations of NATURE and ART, and adapted the _make_ of _one_ to the _formation_ of the other, with a consistency no man of common comprehension will presume to dispute, we proceed to an impartial examination of the letter B, which represents the mode of SHOEING adopted, and some time persevered in, at a place of veterinary celebrity, upon the discontinuance of the very _short-lived_ concave shoe. As it is a remark of long standing, that the _exterior_ strikes _first_, so we shall find here, that, upon a superficial survey of the letter B, there is a neatness in the execution, that seems to excite attention, and command respect; but when it is critically examined with the eye of precision, and its deficiencies pointed out, it then loses all power of permanent attraction, and will advance no well-founded claim to approbation or imitation. Admitting (as it is presumed no opposition whatever arises to the fact) that the _wall_ of the FOOT represented by Fig. 1, should have its bearing upon the properly-adapted part of the shoe, ascertained by referring to Fig. 5 of E, and continued home to the extreme point of the heel accurately terminated by the Fig. 7 of C; let us see what would be the inevitable consequence of having the shoes an inch and a half too short at each heel, as represented by Fig. 3 of B, where NATURE, REASON, OBSERVATION, and EXPERIENCE, concentrate their whole force to demonstrate the consistency, the safety, in fact, the indispensible necessity, of its being continued to Fig. 4 of B, as is already explained by previous reference to Fig. 7 of C.
