SOME MISTAKES B¥ TBE WRITER AND 

 OTHERS, WITS A FLEA FOR PROMPT 

 AND EXPLICIT CORRECTION IN A 

 JOURNAL OF GENERAL CIRCU- 

 LATION AMONG SCIENTISTS 



Long contemplated, the immediate occasion 

 of this article is indicated in the following 

 statement, substantially a copy of a letter 

 dated January 31, 1911, and addressed to Dr. 

 Ales Hrdlicka, curator of the Anthropological 

 Division of the TJ. S. National Museum. 



I submit two calvas and this statement. In 

 February, 1880, there was received at my depart- 

 ment of Cornell University (then including human 

 anatomy) the head of a mulatto of medium color. 

 From the features it was believed to be a male, 

 and in my absence the age was estimated by Pro- 

 fessor S. H. Gage at between 28 and 35 years.^ 

 The brain was hardened in situ by Professor Gage 

 by the injection of the preservative through the 

 arteries, and then removed by the sagittal division 

 of the calva.^ The calva was prepared and dated 

 by Professor Gage, and later given the number, 

 322, of the brain.= The rest of the skull, with the 



' Professor Gage has since informed me that he 

 thinks the head was sent from New York by the 

 late Dr. M. J. Eoberts; also that there was never 

 any doubt in his mind as to the sex; probably it 

 was stated in the letter of transmission.
