broad and squared base ; while the second horn lacks the compressed 

 form so often seen in the black species. The horns of cows are longer 

 and more slender, the record length of the front one being 62^ inches. 

 The nostril is larger and more slit-like than in the black species ; the 

 situation of the eye is well behind the line of the axis of the second horn ; 

 and the ear is taller, more tubular, and more pointed at the tip. The 

 crowns of the upper cheek-teeth, as compared with those of the black 

 rhinoceros, are taller and show a more complicated pattern on their 

 grinding surfaces, which are horizontal throughout, in place of ridged, 

 thus admitting of a mill-like, in place of a champing, action. This is 

 in correlation with the grazing habit, distinctive of the present species.

In walking, the head is carried low, in consequence of which the tips 

 of such horns as curve forwards are worn to a smooth facet in con- 

 sequence of being pushed along the ground. The second horn is 

 generally a good deal smaller than the front one, and may be reduced 

 to a mere boss, or even, as in the undermentioned instance, practically 

 absent. 



Among a collection of, mostly anthropological, photographs made 

 in 1870 by Mr. Ernest Heritte, Consul-General of France at the Cape 

 of Good Hope, and presented in 1 906 by Colonel A. G. Anson to the 

 British Museum (Natural History), is one of a freshly killed white 

 rhinoceros, which is of interest from two points of view. In the first 

 place, it is the only photograph of an entire specimen of the South
