    tation from worms, hysteria, and other nervous states. Restlessness, or uneasy sleep, is observed most usually in inflammatory and acute febrile affections, nervousness, cardiac and aneurismal diseases in the thorax, and dyspeptic states. Sudden startings from sleep are noticed in hydrocephalus, diseases of the heart, and asthmatic cases generally. Dreaming is not necessarily morbid, but when constant and unpleasant, generally denotes disorder of the digestive organs. Nightmare is of similar import. Slight convulsions during sleep, are frequently noticed in children, and portend worms, or other in- testinal irritation. Unrefreshing sleep argues some inflammatory or nervous state; and any alteration of the respiration during sleep betokens similar causes. II].—THE INTERPRETATION OF DERANGEMENTS OF THE NERVOUS SYSTEM. The symptoms, whose interpretation we have just completed, I have named General, because they are signs of very various affec- tions in different organs and tissues. Those upon whose consider- ation we are now about to enter, are moreof a Special character, and their indication will be, therefore, proportionally limited. Yet we shall find here, too, many instances of an extended application. We commence with the symptoms more distinctly referable to the Nervous SysTem. The Nervous System comprises the Brain, the Cerebellum, Medulla Oblongata, Spinal Cord, the Cerebro-spinal and the Ganglionic Nerves. The Brarin may be considered as the seat of INTELLIGENCE, sensation, will—in fact, of power. It consists of gray matter, forming the bulk of the convolutions, and acting as a cap (so to speak) to the white and fibrous-looking portion, which is principally composed of the great nervous tracts, extending to the nerves and other parts of this system. Whilst intelligence is supposed to take up its abode chiefly in the convolutions, or the gray matter, the white substance may be deemed merely the trans- mission fibres between the nerves and the gray. Besides being func- tionally distinct, these are especially anatomically different. ‘Thus, the gray substance is composed of ‘“ nucleated cells,” of varying size and shape, whilst the white is an assemblage of minute tubes, which are of smaller dimensions towards the gray matter, than towards the nerves. They are also of various shapes; cylindrical, varicose, or regular throughout, besides many of a flat or riband-like appearance. re
