MANIA

(Gr. fAot,ivofji.a.i, 1 rage.) Madne . It is defined to be delirium, unattended by fever, in which both judgment and memory are impaired, and the irritability of the body diminished so as to resist many morbid causes. There is a false perception of things, marked by incoherence or raving, and resentment of restraint. It is divided into melancholic and furious: the former marked by dejection of spirits; the latter by violent exertion of strength, malice to particular individuals, and repugnance to scenes and places before agreeable. Di ection has shown that in cases of madne there is usually eifusion of water into the cavities of tiie brain, or appearances of previous inflammation of its membranes, or hardne of its substance, or peculiar thickne of the skull; and it has lately been stated that chemical analysis has shown an exce or deficiency of phosphorus in the composition of the brain in cases of madne and idiotcy.
