WEEKS— HEREDITY OF EPILEPSY 



[April 19, 



epileptics, 4 feeble-minded, i insane, 8 tainted and 7 seemingly 

 normal. These latter came from two fraternities, where in one 

 case the father's insanity seemed to be traumatic and in the other 

 alcoholic. 



NuLLiPLEX X Simplex 



Under this classification we have grouped separately those fra- 

 ternities in which one parent was alcoholic. 



In the consideration of the fraternities where one of the parents 

 is epileptic or feeble-minded, and the other alcoholic, we have 

 classed as alcoholic all of those parents who are habitually hard 

 drinkers, or who go on frequent sprees. 



In thirty-five fraternities there were 226 conceptions; 21 are yet 

 too young to be classified, 79 died before 14 years of age (which is

Fig. 6. In tliis case the father is epileptic and the mother is neurotic. 

 The father had an epileptic brother and an epileptic sister. There were three 

 children; the first was normal, the second epileptic and the third too young 

 as yet for classification. This is an illustration of the nuUiplex X simplex 

 type of mating. E, epileptic; F, feeble-minded; A'', normal; T, tubercular; 

 A, alcoholic. Case, 3,402. 



35 per cent., a high death rate). Of the 126 remaining, 39 are epi- 

 leptic, 38 feeble-minded, and 28 showing some other taint ( i insane, 

 3 migrainous, 16 neurotic, 5 alcoholic and 3 sexually immoral), with 

 only 21 apparently normal. 



In these matings of the type nulliplex X simplex, we should 

 expect 50 per cent, nulliplex, that is, epileptic or feeble-minded and 

 50 per cent, simplex, that is, apparently normal or showing only 

 some slight defect. We have, however, 61 per cent, nulliplex, 39 

 per cent, simplex, the increase over the expectation being probably
