NicoBARESE Brain. 



With regard to the ethnic position of the Nicobarese there exists 

 considerable doubt. They are very different from the Andamanese. 

 Their color is a light brown, the hair is straight and black, and 

 apparently they are of ancient Mongolian origin with probably no 

 admixture of Papuan or Negrito elements. Their stature is medium 

 (158-163 cm.), not small as are the Andamanese. 



The brain is that of an individual from Kar Nicobar, a male, 

 aged 25, who died of hypertrophic cirrhosis of the liver and fatty 

 degeneration of the heart in the hospital at Port Blair. The brain 

 weighed 49 ounces avoirdupois or 1,389 grams. The body-weight 

 was 136.5 pounds, while the stature was 170 cm. 



Major Anderson injected about 10 c.c. of 5 per cent, formalde- 

 hyde into the ventricles through the tuber and immersed the brain 

 in the same mixture. The specimen reached me in March, 1906, 

 a little over three months after its removal from the head. 



Its present weight, divested of the cerebral pia-arachnoid, is 

 1,257 grams. The brain is somewhat flattened and elongated. The 

 fissural pattern is fairly good but not as complex as in the average
