Little or no information of importance regarding the clinical 

 histories of these cases was available. They were simply cases 

 that had come to autopsy and their brains had been preserved 

 as a routine measure. Even so, however, the results from the 

 four should give us a close approximation to the conditions 

 present in the average cerebellum as it appears in the hospital 

 population — a group probably somewhat below the average for 

 the community at large in the development of the nervous 

 system. 



Nine cerebella from mental defectives, who had died at the 

 Vineland Training School, were selected from the collection in 

 The Wistar Institute Museum and a study was made of each 

 case. Several of these cases have been described by Goddard 

 (Feeble-mindedness, New York, 1914), and his case numbers, 

 preceded by 'G,' enclosed in parentheses, are given after the 

 serial numbers which these brains have on the records of The 

 Wistar Institute. The histories of these defectives, all whites, 

 and listed in table 2 and table 4, are as follows: 



14880, male, age 23 years; alcoholism and insanity in family; three 

 miscarriages before the birth of this child; he had had convulsions, 

 marasmus at one year, measles at four years; small in size, head small; 

 poor motor power, poor gait, poor speech; no will power; right handed; 

 fair memory. 



15144, male, age 34 years; height, 6 ft. 3 in.; brain weight 1619 

 grams; supposed insanity and feeble-mindedness on father's side; no 

 deaths in infancy in family; had whooping-cough, measles, and pneu- 

 monia; walked at three years; head, bullet-shaped; right side not 

 developed; dragged feet, could thread needles and tie shoes; talked 

 little; could not count. 



15145, male, age 24 years; brain weight 1491 grams; normal (?) 

 heredity; first child dead; had measles and whooping-cough; epileptic; 

 abscess on right hip; weak heart; normal electric reaction; grip, rt. 

 0-lt. 0. 



15214, male, age 26 years; brain weight 1065 grams; father alcoholic; 

 five children died young; first child a 'lunatic,' followed by two mis- 

 carriages; two other children mentally defective; this, the sixth child; 

 probably congenitally luetic; spasms at nine months; walked at three 

 years; talked at four years; had measles and whooping-cough, ab- 

 scesses, scrofula, Pott's disease; hunchback, T.B. of vertebrae; weak 

 heart; was apparently normal until nine months; not strong enough to 

 work; grip, rt. 18-lt. 22; could dress self; learns quickly, forgets soon. 

 This case is presented by itself in table 4.
