derable sizein one brain, situated in widely differentportions of the brain. In only a comparatively small numberof cases is it possible to determine theexact nature of the growth, and often theconclusion at which one arrives is littlemore than a shrewd guess. Secondarygrowths in the brain usually are of thesame nature as the primary one in otherportions of the body. Evidences of syph-ilis or tuberculosis in a person sufferingfrom tumor of the brain points to theprobable nature of the growth. Inher-ited syphilis very rarely gives rise totumor of the brain. The most commoncerebral growths in children are thetubercular, and these may occur in child-hood without the signs of tuberculosisin other portions of the body. The cere-bellum, comparatively speaking, is re-markably exempt from syphilitic tumors,but the tubercular and the gliomatousare the most frequent here. Growths inthe cortex are usually syphilitic, tuber-cular, or sarcomatous. Gliomata andsarcomata frequently occur in the cen-

The symptoms of mostgrowths of the brain are at first favorablymodified by active antisyphilitic treat-ment. If the improvement is very greatand can be maintained by such treat-ment, it is strong evidence in favor ofthe syphilitic nature of the growth. Etiology.—Predisposing Causes.—Cerebral growths may occur at any timeof life. The third decade furnishes thelargest number, about 20 per cent.; thefirst and fourthabout 18.5 per cent, each;and the second and fifth about 14 percent. each. They are rare in extreme oldage. Steffen has reported a case of tumorof the brain in an infant four weeks old. The character of the tumor variesconsiderably with the different periods oflife. Tubercular, cystic, gliomatous, andsarcomatous varieties are frequent inchildhood and early adult life. Thetubercular largely predominating inchi
