But, leaving the functions and organs, which belong to all living and growing beings in common, and entering the province of animal life and animal law proper, we everywhere observe a significant departure from the angular and cylindrical forms of the mineral and vegetable kingdoms, and an approach, in proportion to the rank and value of the organ and its use, toward an ideal or model, which is neither conical nor heart-shaped, exactly, but such a modification of them as carries the standard figure farthest from that uniformity of curve which marks a globe, from the parallelism of fibre which belongs to the cylinder, and from the flatness of base and sharpness of apex which bound the cone. The limbs that take their shape from the muscles of locomotion, and the internal parts concerned in those high vital offices, of which minerals and vegetables are wholly destitute, are examples and proof of the configuration proper to the animal kingdom. The thigh, leg, arm, fore-arm, finger, the neck and shoulders, the chest, and the abdomen meeting it and resting on the pelvic bones, are felt to be beautiful or true to the standard form as they taper or conform to this intuitive life-type. The glands are all larger at one end than the other, and those that have the highest uses are most conspicuously so, and have the best defined and most elegant contour. The descending grade of figure and function is marked by tendency to roundness and flatness. In the uses, actions and positions of these organs, there is nothing mechanical to determine their figure. The human stomach is remarkable for an elegance of form and conformity to the ideal or pattern configuration, to a degree that seems to have no other cause, and, therefore, well supports the doctrine that the importance of its office confers such excellence of shape. The facts of comparative anatomy cannot be introduced with convenience, but they are believed to be in the happiest agreement and strongest corroboration. The heart, lungs and brain, are eminent instances of the principle. They hold a very high rank in the organization, and, while their automatic relations, uses and actions are _toto cœlo_ dissimilar, their agreement with each other in general style of configuration, and their common tendency toward the standard intimated, is most remarkable.
