ANATOMY 



By practice Hatai has been able to reduce the difference between the 

 first and second filling to less than one per cent. The cranial capacity 

 thus determined in the terms of shot weight can be transformed into 

 brain weight as follows: by dividing the weight of the shot in the case 

 of the males by 5.980 and in the case of the females by 6.009. The re- 

 lations between the cranial capacity, in terms of shot weight, and the 

 body weight are represented by the formulas (8) and (9) .
