European. In conséquence of the small angle of torsion, both tubercles lie rather ventrally, 

 that is to say, when the humérus is placed with the dorsal side on a table, the tub. maj. 

 nses higher from the surface of the table and the tub. min. is placed more towards the 

 médian line than in European spécimens. Thus the sulcus intertubercularis lies more in the 

 middle of the ventral surface, and without the curvature occurring with Europeans it runs 

 down almost parallel with the axis. The tuberositas deltoidea reaches rather far downwards. 

 The foramen nutritium is situated on the margo medialis below the middle. The latéral 

 epicondyle is only moderately developed. The angle between axis of diaphyse and axis of 

 lower articular surface more nearly approaches a right angle, and the lower articular surface itself 

 is more curved than with European humeri. The fossa radialis, in Europeans only a shallow 

 concavity, is almost as large and deep as the fossa coronoidea, besides it is situated more 

 towards the médian line; the bon)' ridge that divides both fossae and which in Europeans 

 déviâtes strongly laterally, hère runs more nearly parallel with the axis of the diaphyse. Ail 

 thèse peculiarities, met with by MARTIN [1905, 587, fig. jy] in a still greater measure in the 

 natives of the Malay Peninsula, form characteristics of primitive races. The angle of torsion, 

 determined with MARTIN's [1903, 129] paralellograph, is on an average 138 ; for Europeans, 

 according to BROCA, it is 161.5°. Lambert [1904, 81] gives of Melanesians 139° and of 

 Australians 134.5 . The capito-diaphysal angle on an average is 41. 5 , the condylo-diaphysal 

 angle S0.5 ; with 30 Swiss humeri MARTIN [1905, 593] found for the latter 77°. 



U 1 n a. One spécimen, 266 m. m. long, corresponding with a standing height of 1672 

 (maie) or 17 19 m. m. (female). The crista m. supinat. well developed, and a crista interossea 

 which makes the transverse section in the middle triangular, but entirely disappears below, 

 so that at 3 cm. above the lower articular surface the thinnest part (circumference 34 m. m.) 

 is found. In the middle the maximum diameter is 16.5, the minimum diameter 13 m. m., the 

 circumference only 49 m. m.. European ulnae of the same length are much heavier. The 

 faciès volaris is less concave than usual. The curvature of the diaphyse is in the upper part 

 in front, in the lower part behind, slightly concave. A similar S-shaped curvature, but less 

 pronounced, appears when it is examined from behind : the medial side concave at the top, 

 convex below. The articular surface of the olecranon is only 13 m. m. long, but 26 m. m. 

 broad, and is separated by a rough, slightly raised, transverse ridge from the almost equally 

 large articular surface of the proc. coronoides. There is a great resemblance with the ulna of 

 a New-Hollander, drawn by FISCHER [1903, 166, fig. 1 B], only in the latter the décimal 

 relation between the length of olecranon and ulna is 2.57, in the spécimen hère described 

 1.65. The proc. coronoides ends with a small sharp crista that bends proximally, the extrême 

 edge thus being only 22 m. m. away from the edge of the olecranon. A wide nutrient foramen 

 lies ventrally between the proximal and the middle third part. 



Radius. Two left radii, one right, ail extremely slender and without marked curvature. 

 The length, being from 251 to 260 m. m. (average 255 m. m.), corresponds (MANOUVRIER) with 

 a standing height of 1703 (maie) or 1774 m. m. (female), much too great for the actual stature 

 of the people of Wendèsi. The minimum circumference (39 m. m.), in European radii situated 

 just below the tuberositas radii, notwithstanding the well developed crista interossea, is 

 found 2 — 3 cm. below the middle. The tuberositas radii is found more proximal than in 

 Europeans, in one spécimen at only 1 cm. distance from the articular circumference, so
