The capacity of the brain-cavity of the Proboscis-Monkey has been measured 

 by means of hemp seed, since fissura orbitalis etc. has been closed with some cotton 

 and the following results have been obtained. 



To commence with the male series in the present collection there are rather 

 great variations as to the capacity of the brain-cavity. The two oldest specimens 

 (original numbers 13 and 17) have a brain capacity of 112 ccm. and 85 ccm. respec- 

 tively. Both these males are apparently quite fullgrown having the basioccipital 

 suture quite closed, but the molars are only moderately worn. The rest of the male 

 series are all younger animals, thongh still fullgrown and in all the basioccipital 

 suture is visible. As seen by the following table the capacity of the brain-cavity 

 is rather variable. 



Specimen No. 14 has a brain capacity of 105 ccm.

As the greatest number of the specimens in the present series has been collected 

 at the same locality it seems impossible that the capacity of the brain-cavity may 

 serve to distinguish different races. 



As to the females there seems to be less variability as to the capacity of the 

 brain-cavity as will be seen by the following measurements. 



Specimen No. 20 has a brain capacity of 85 ccm.

Among the present collection there is a young female specimen in milk denti- 

 tion, and in this specimen the brain-cavity has a capacity of 75 ccm. thus almost 

 the same as that of the smallest, though quite fullgrown female specimen.
