and of some drugs, or excessive muscular action. It 

 is attended with violent action of the heart, increase 

 in the cardiac area of dulness and increased arterial 

 pressure, headache, vertigo, dyspnea, palpitation, and 

 pain in the heart. H., Compensatory, that following 

 dilatation of the heart, or obstructive or regurgitant 

 valvular disease, and produced by the efforts of that 

 organ to make good the deficiency resulting from 

 failing cardiac power. Let the circulation be restored, 

 and the previous distressing symptoms will disappear. 

 H., Concentric, increase in the thickness of the cardiac 

 walls, without increase in the size of the organ, but with 

 diminution in the capacity of its chambers. H., Ex- 

 centric, cardiac hypertrophy, with dilatation. H., 

 False, the thickening of the heart- wall is due to some 

 extent to an adventitious fibrous growth. H., Idio- 

 pathic, that developing in the absence of other disease 

 of the heart's structure, or of the structure of other 

 organs. H., Numerical, an actual increase in the 

 number of the constituent muscle-cells of the heart- 

 walls. H., Simple, the walls are thicker than usual, 

 the size of the cavities remaining unchanged. H., 

 True, the hypertrophy consists in an increase in the 

 muscular tissue itself.

 are as follows: Charcot's Method; it consists in

 Method ; the hypnotism is induced by having the 

 patient sit with his back to the light and look steadily 

 at a rapidly revolving mirror placed two or three feet 

 from him, on which the light is directly shining. The 

 constant flash of the light soon wearies the eyes ami 

 produces sleep. Nancy Method; in this method 

 hypnotism is induced by means of suggestion entirely.

 Voisin's Method ; Braidism ; the patient 

 upon the broad of his back and gazes steadily at 

 a bright silvered ball, suspended from the ceiling 

 and at a distance of about nine inches from his eve-. 

 The method of fascination is also used, the operator 

 gazing fixedly in the subject's eyes at a distance of 

 about a foot. See, also, Somnambulism.
