Goddard2 states that the dynamometer itself is a measure of theintelligence among the mental defectives. They are unable to exerttheir strength in obedience to the command, Squeeze this as hardas possible, but whenever an exercise of strength is called forthby a natural situation and their action is impulsive or Fig. 1.—Brain of an adult idiot with congenital infantile cerebral of brain, 820 grams. Microgyria especially in right atrophy and sclerosis of riKht hemisphere. Patient died in epilepticstatus. (From preparation of pathological laboratory of Central IndianaHospital for the Insane.) one discovers at once how great is the strength. I am familiarwith the cases of several patients who could hardly make an im-pression upon the dynamometer, but, when they lost control ofthemselves and offered resistance, it required the assistance ofthree or four attendants to restrain them. The cortical lesions may be of the most variable nature. Theremay be a thrombosis, a hemorrhage, a tumor and encephalitis,or a gumma. At times these lesions are congenital as will be notedin Fig. 1. In these cases one may expect to find two types of symp-toms, first the special disturbances which are brought about bya circumscribed lesion as, for example,
