APPENDIX. 201 



Os Pyramidak. — Transverse diameter, 5.5 ; greatest anteroposterior diameter, 4.7 ; vertical 

 diameter, 2.3. 



Os Magnum. — Antero-posterior diameter, 3.5 ; vertical and transverse diameter, 2.7. The 

 remaining five bones, although carpals, are too much injured to admit of a specific description. 



Metacarpals. — Of these we have the second and fourth of the right side. 



Inches. 



Length of the second 6.3 



Width, of the second 2.4 



Length of the fourth metacarpal . . . . . . . . . . . . 5.9 



\Vidth of the fourth metacarpal ............ 2.7 



Phalanges. — These are the first of the index and of the ring finger of the right hand ; each 

 about 3.1 long by 2.7 broad. Transversely concave on the face of the metacarpal articulation, 

 rounded on the opposite extremity. 



POSTERIOR EXTREMITIES. 



In contrast with the anterior, these are not so clumsy, owing to the delicacy and length of 

 the femur, as well as of the bones of the legs ; for the great weight of the head, tusks, and 

 thorax, required a more massive structure in the former. 



Os Innominatum. — In consequence of the destructibility of the pelvic bones, we have to 

 lament the loss of much of the pelvis ; the only portions preserved are two large fragments of the 

 right half, i.e. the middle inferior portion of the iliac, and of the ilio-ischiatic bones. The former 

 piece, in length 13.4, contributed to form the great iliac fossa ; the latter, in length 16.9,.includes in 

 it the entire cotyloid cavity. This cavity is very large, its transverse diameter being 5.5, the depth 

 very slight in proportion, of a quadro-circular figure, limited by a periphery with a sharp, cutting 

 margin, which is interrupted inferiorly by a canal soon lost in a fossa excavated at the base of 

 this cotyloid cavity. 



Femur. — The description is chiefly drawn from the left, which is in a rare state of preser- 

 vation. 



A diagonal from the head to the external condyle measures 37.0. Width of the neck from 

 its internal margin to the extremity of the great trochanter, 9.4. Width of the tibial extremity 

 between the two tuberosities, 9.1. 



The head is constituted by an hemispherical eminence with smooth superficies, destitute of 

 any sort of foramen for the round ligament. 



The right femur is reduced to a piece 23.6 long, and consists of the upper half of the bone, 

 in a fragmentary condition. 



Tibia. — In the legs this skeleton has suffered the most injury. In fact, only a portion of 

 the tibia, about 21.3 in length, and the fibula of the left side, remain.
