THE BRAINS OF THREE BROTHERS. By Edw. Anthony Spitzka. 

 Columbia University, New York City. 



Opportunities for demonstrating the influence of heredity in the con- 

 figuration of the human brain are exceedingly rare; adult material of 

 this kind has only once before been described, and by the same writer, 

 before this association three years ago in the case of the brains of the two 

 distinguished physicians, Seguin father and son. It may be remem- 

 bered that in the Seguin brains there were found some notable resem- 

 blances which could be attributed to hereditary transmission. The writer 

 again had the good fortune to test the question of encephalic morpho- 

 logical transmission in the brains of three brothers recently executed 

 together in New York State. In the search for positive evidences of 

 hereditary resemblance, only such parts of the cerebrum as are subject 

 to great range of variation in different brains could be depended upon 

 to support the proposition; it was found, in fact, that peculiarities of 

 anatomical configuration of this class, uncommon enough in the general 

 run of brains as they come to the hands of anatomists, were similarly
