THE VOYAGE OF H.M.S. CHALLENGER. 
Measurements of the Bones. 
The length of the bones of the shaft of the upper limb was taken on a Broca's 
osteometric board, made by M. Collin, Paris. I measured the maximum length of each 
humerus from the top of the head to the most projecting part of the trochlear surface. In 
each radius I measured the length from the top of the radius to both the base and the 
tip of the styloid j)rocess, and in each ulna from the summit of the olecranon to both the 
inferior articular surface and the tip of the styloid process. The measurement to the tip 
of the styloid process in both radius and ulna gives the maximum length of each of those 
bones. In takino- these measurements I was desirous of ascertainino; the absolute length 
of each bone, the relative length of the corresponding bones in opposite limbs of the 
same skeleton, and the proportionate length which the bones of the forearm bore to the 
bone of the upper arm in the same limb. 
The longest humerus was in the right arm of one of the Negro skeletons, in which it 
measured 372 mm.; the longest humerus in each of the two other Negros was 339 and 
324 mm., and in the two Negresses 331 and 307 mm.^ In the male skeleton, presented 
by Dr. Anderson as a Hindoo, the left humerus was 370 mm. long ; in the other male 
Hindoo each humerus was 318 mm., and in the female the right humerus was 285 mm. 
In the Sikh the right humerus was 354 mm., in the Chinese 298 mm., and in the Malay 
the left humerus was 307 mm. In the male Australians the maximum humerus was 352 
mm., in the Riverina skeleton; then followed 348 mm. in the Queensland, 335 in the 
Manly Cove, 334 in the Eucla, 330 in the Perth, and 325 mm. in the Swan Hill skeleton ; 
whilst in the female from West Victoria the right humerus was only 287 mm. The 
right humerus of the male New Zealander from Te Aroha was 335 mm., and the left in 
the Otago skeleton was 326 mm. In the one female Oahuan the maximum humerus was 
311 mm., in the other 267 mm. In the male Esquimaux the right humerus was 343 
mm., in the female 326 mm. In the male Lapp the right humerus was 299 mm,, in 
the female 280 mm. In the Bushman the right humerus was 288 mm. long. The 
longest humerus in the Andaman Islanders Avas 281 mm. in one skeleton, 278 in 
another, 253 in a third, and 248 in a fourth. 
The longest radius, the length of which was 287 mm., was in the right arm 
of the Negro skeleton which also had the longest humerus. In the other Negros 
the maximum radius was 273 and 258 mm., and in the Negresses 245 and 242 mm. 
In Dr. Anderson's male Hindoo the maximum radius was 282 mm., in the other male 
Hindoo 257, and in the female 233 mm. In the Sikh the longest radius was 267, in the 
Malay 250, and in the Chinese 227 mm. Both radii of the Queensland and the left 
radius of the Riverina skeleton measured 270 mm., and the maximum radius in the 
1 In Table XIV., p. 109, the maximum lengths of the humerus and radius in thirty of the skeletons which I have 
measured is recorded.
