"He first directed their attention to the bones, and taught them in a few words their nature and uses, as the pillars and safeguards of the body;--the shank, the joint, and the ligaments, forming the branches of this part of the analysis. He then led them to imagine these bones clothed with the fleshy parts, or muscles, of which the mass, the ligaments, and the sinews, formed the branches. He explained the nature of their contraction; and shewed them, that the muscles being fastened at one end by the ligament to a bone, its contraction pulled the sinew at the other, and thus bent the joint which lay between them.--He then taught them the nature and uses of the several viscera, which occupy the chest and belly, and their connection with each other. This prepared the way for considering the nature of the fluids of the body, particularly the blood, and its circulation from the heart and lungs by the arteries, and to them again by the veins, with the pulsation of the one, and the valves of the other. The passage of the blood through the lungs, and the uses of the air-cells and blood-vessels in that organ were described; when the boys, (having previously had a lesson on the nature of water, atmospheric air, and the gases,) readily understood the importance of bringing the oxygen into contact with the blood, for its renovation from the venous to the arterial state. The nature of the stomach and of digestion, of the intestines, lacteals, and absorbents, was next explained, more in regard to their nature than their names,--which last were most difficult to remember;--but the knowledge of the function, invariably assisted the memory in recalling the name of the organ. They were next made acquainted with the brain, the spinal cord, and the nervous system generally, as the source of motion in the muscles, and the medium of sensation in conveying intelligence from the several organs of sense to the brain, by which alone the soul, in some way unknown, receives intelligence of outward objects. This prepared the way for an account of the organs of sense, and the mechanism of their parts; and lastly, they were made acquainted with the integuments, skin, hair, and nails, with the most obvious of their peculiarities.--On all these they were assiduously and repeatedly catechised, till the truths were not only understood, but were in some degree familiar to them. In this they were greatly assisted by a consideration of their own bodies; which Mr Gall took care to make a kind of text-book, not only for making him better understood, but for enabling them more easily and permanently to remember what he told them. When he shewed them, by their hands, feet, and face, the ramifications of the blood-vessels and nerves,--the mechanism of the joints,--the contraction of the various muscles,--the situation and particular uses of which he himself did not even know, but which were nevertheless moved at their own will, and whenever they
