This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1860 edition. Excerpt: ... A TREATISE ON MEDICAL ELECTRICITY. CHAPTER I. FORMS OF ELECTRICITY. In the present state of physical science it is generally admitted that all bodies contain a very subtle fluid called natural electricity, and composed of two contrary fluids, which are termed positive and negative electricity. We suppose these fluids to consist of an infinite number of smallest particles or molecules, each of which possesses attractive and repulsive powers, the molecules of one attracting those of the other, whilst the molecules of the same fluid repel each other. Whilst bodies are at rest, these fluids exist in such proportion that, although they do not destrov each other, their effect is counterbalanced: since at the same distance the attractive power of one of the fluids is equal to the repulsive power of the other. Natural electricity must therefore be decomposed, if au action shall be perceptible. Decomposition of the natu ral electricity is brought about as soon as disturbances of any kind are impressed upon bodies, whereby a derangement is produced in the equilibrium of the molecules; as for instance, when bodies are subjected to friction, heat, chemical action, etc. By such and other means an electro-motive force is called into existence, which separates from each other the two fluids formerly united; natural electricity is decomposed and active electricity liberated, the nature and intensity of which present certain differences, which depend upon the nature of the body from which it is derived and upon the action by which it is developed; but active electricity, whatever may be its source, is identical in its nature; it exerts attractive and repulsive powers, produces heat, light, shocks, magnetism, and is ready to tear asunder the elements of...
