Sub-Himalayan Fossil Remains

rate measurements, but it bears as great a general resemblance to 

 that of the Indian rhinoceros as do the other parts of the skeleton. 



The humerus, figs. 1, 2, PI. XVII, having its radius and ulna at- 

 tached, was discovered by ourselves very close to the place whence we 

 excavated the femur and tibia forming the subject of PI. XVIII. With 

 the exception of the deltoid crest, this humerus is perfect, and has afford- 

 ed the dimensions which ,enter into the first column of the table. For 

 the purpose of comparison the following five columns are here added. 

 The proportions of the Indian and Sumatra small species of rhinoce- 

 ros are deduced from Cuvier's table ; those of the fossil specimens 

 are of course from the table of dimensions. The length of the bone 

 is assumed as the unit, and the measures of other parts referred to it 

 in order to obtain their comparative values.

fossil 



The Sumatra rhinoceros (small species) concurs with the 

 Indian rhinoceros in having the length taken to the external condyle 

 longer than that taken to the internal. The Javanese and the larger 

 Sumatra species also accord with the fossil in this respect, but not so 

 nearly as the small Sumatra species, which has consequently been 

 introduced into the above table. 



The length of the fossil humerus, figs. 1, 2, PI. XVII, exceeds that of 

 any of the existing species : its thickness is, in proportion to the 

 length of the bone, intermediate between the Sumatra and Indian spe- 

 cies. The articulating pully also possesses a development interme- 

 diate in value to those of the two existing species. The breadth at 

 the condyles is in the same proportion or nearly so as that of the 

 Indian rhinoceros. The radius is in length, considered with refer- 

 ence to length of femur, a little less than in the Indian and somewhat in 

 excess of the small Sumatra species ; the remaining two dimensions of 

 this bone yield values intermediate to those of the two existing rhinoce- 

 roses. These remarks apply to the deductions for fig. 1 ; nor would it
