    79. Electrics may also be excited by rubbing tliem with non- elcctrics. 80. If a body B be brought into the neighbourhood of an elec- trified body A, B becomes electrified by position. 81. If a body B'be insulated, that is, in contact with electrics only, when brought into the neighbourhood of an electrified body A, a spark passes between them, accompanied by noise. B becomes permanently electrified, and the electricity of A is di- minished. 82. When a body A has imparted electricity to another body B, they repel each other, unless B shall have afterwards imparted all its electricity to other bodies. 83. Bodies repel each other, when both are positively or both negatively electrified. 84-. Bodies attract each other, when'the one is positively and the other negatively electrified. 85. If either of the bodies be in the natural state, they will neither attract nor repel each other. 86. The spark (80) is accompanied by intense increase of tem- perature, and will kindle inflammable bodies. S7. It produces very remarkable chemical effects, depending chiefly on sudden and momentary increase of temperature, and •n tlie light produced. 88. Electricity acts on the living system as a stimulus GALVANISM. 89. The phenomena of galvanism seem to depend solely on the agency of electricity, excited during certain chemical actions. 90. It is excited by arranging at least three heterogeneous bo- dies (for instance, two metals and a fluid) in such a manner, that the two metals be in direct contact with each otlier, in one part, and have the fluid interposed between them in another. 91. The pile of Volta, by which it is rendered most manifest, is constructed, by combining a series of simple galvanic arcs into one continuous circle, in one uniform order of arrangement. 92. The solids capable of exciting galvanism, are the metals and charcoal j and the most efficient fluids are certain saline so- lutions. 93. The effects of the simple galvanic circle on the animal body, are the production of a sensation of light when applied to the eye; of an acid taste on the tongue •, and the excitement of tlie muscles through the medium of the nerves. 94. The pile, when well constructed, besides these effects, also gives a shock and spark resembling those of electricity (80), and proves, that the galvanic action is always accompanied by
