Not indexed. Not illustrated. 1848 edition. Excerpt: ... ON THE ARCHETYPE AND HOMOLOGIES OF THE VERTEBRATE SKELETON. Chapter I.--Special Homology. Introduction. When the structure of organized beings began to be investigated, the parts, as they were observed, were described under names or phrases suggested by their forms, proportions, relative position, or likeness to some familiar object. Much of the nomenclature of human anatomy has thus arisen, especially that of the osseous system, which, with the rest of mans frame, was studied originally from an insulated point of view, and irrespective of any other animal structure or any common type.

So when the exigences of the veterinary surgeon, or the desire of the naturalist to penetrate beneath the superficial characters of his favourite class, led them to anatomise the lower animals, they, in like manner, seldom glanced beyond their immediate subject, and often gave arbitrary names to the parts which they detected.

Thus the dissector of the horse, whose attention was more especially called to the leg as the most common seat of disease in that animal, specified its cannon-bone, its great and small pastern-bones, its coffin-bone, and its nut-bone or coronet: some cranial bones were also named agreeably with their shape, as the os quadratum, for example. The ornithotomist described, in the same irrelative manner, the ossa homoidea, ossa communicantia or interarticularia, the columella and os furcatorium. Petit had his os grele and os en massue- Herissantf his os carre- which, however, is by no means the same bone with the os carre or os quadratum of the hippotomist.

The investigator of reptilian osteology described hatchet-bones and chevronbones, an os annulare or os en ceinture, and an os transversum
