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

 dullary cavity is filled with root fibres. And in its posterior 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 with a sharp metallic instrument. There is also a deeper 

 incision on the external condyloid ridge immediately above the con- 

 dyle. 



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 another 

 individual. 



5. 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 nothing 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. What tends to afford some support to this 

 supposition is the marked 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 Sur- 

 geons, I find is presented by several among the Chinese crania in a 

 more marked degree than in the other races to which my attention 

 was directed.
