EXPLOKATIOX OP THE CAVES OF BORNEO- 287 



2. Two or three fragments of the humerus, in one of which 

 the medullary cavity is filled with root fibres. And in its post- 

 erior aspect near the lower end there are three or four transverse 

 cuts of slight depth, and done, as it would seem from the chipped 

 appearance, by chopping. There is also a deeper incision on the 

 external condyloid ridge immediately above the condyle. 



3. An entire sacrum and a portion of the left os innominatum, 

 probably of the same individual. 



4. A fragment of the right os innominatum belonging to ano- 

 ther individual. Of bones belonging to the lower extremity, the 

 collection includes portions of four thigh bones, one with the 

 lower epiphysis naturally detached. The tibia is represented by 

 three specimens, none of which present anything worthy of remark. 

 The only bone belonging to the foot is a first metatarsal of small size. 



From the above it will be seen that these bones present no- 

 thing of especial interest ; and with respect to the race to which 

 they may have belonged, the information they afford is very 

 meagre. On this point all that can be said is that they may well 

 have belonged to the Malay type, but there is also no apparent 

 reason why they should not have been of Chinese origin. "Whitt 

 tends to afford some support to this supposition is the marksd 

 fulness or bulging of the squamosal in the sphenoidal fossa, to 

 which I have called attention, and which, upon examination of the 

 collection of crania in the Royal College of Surgeons, I find is 

 presented by several among the Chinese crania in a more marked 

 deerree than in the other races to which my attention was directed.
