full. The frontal region is very narrow, shallow, much excavated 

 below, and compressed laterally near the entrance of the Sylvian 

 fissure. The parietal region is low, but prominent laterally ; the 

 occipital region is long, but defective in height ; and the temporal 

 region is long, but narrow. 



The cerebrum overlaps the cerebellum by *5 inch, which is as 

 great an absolute overlap as is usual in European brains, but less 

 relatively to the length of the brain, which is very long in the Bush- 

 woman. 



The fissures, lobes, and convolutions are then described at length, 

 and compared with those of the ordinary European brain, with those 

 of the Hottentot Venus's brain figured by Gratiolet, arid with those 

 of the young Chimpanzee. It is impossible to give in an abstract 

 even an outline of the facts recorded in this part of the paper. 



The general result of the inquiry is to show that the fissures are 

 rather more complex than in the brain of the Hottentot Venus, but 

 much less so than in the European. They are rather more complex 

 on the left than on the right side of the brain. They are widely 

 separated from those of the Ape's brain. 



The author concludes 1. That all the convolutions proper to 

 man are present, but, as compared with the European brain, are 

 much more simple, and less marked with secondary sulci. The 

 greatest deficiency is in the occipital and orbital convolutions. 



2. That the convolutions, taken generally, are rather more complex 

 than those represented in Gratiolet's figure of the Hottentot Venus's 

 brain, which may be partly due to the obliteration of details in the 

 latter during its long period of preservation. 



3 & 4. That the resemblance between the Bushwoman's brain 

 and the Hottentot Venus's brain is sufficient to justify the conclusion 

 that the latter was not an idiot, or a defectively developed individual ; 

 but both brains, as compared with the European, have an infantile 

 simplicity, characteristic partly of sex, but chiefly of race. 



5. That the convolutions being more simple, can be more easily 

 traced and compared on the two sides than usual, but still show 

 abundant evidences of the asymmetry characteristic of man. 



6. That there is a greater difference between the Bushwoman's 

 cerebrum and the highest Ape's cerebrum than between it and the 

 European cerebrum ; but a less specific difference between it and the
