 certainly those of the white rhinoceros. 1 In 

 the absence of any data, however, they cannot 

 be absolutely proved to have come from the 

 countries through which Mr. Salt travelled, though 

 the presumption that such is the case is strong 

 indeed. Locality and not identity is here the de- 

 bateable point ; as confirmatory of other evidence, 

 we may conveniently insert mention of them here. 



2. When Denham and Clapperton returned 

 home from their Central African expedition of 

 1822-24, they presented to the British Museum 

 two remarkable light-coloured and semi-transparent 

 horns. It is interesting to remember that the 

 horns of the white rhinoceros are pale-coloured on 

 section, and that Sir A. Smith (who had practical 

 experience of R. simus in Southern Africa) himself 

 suggested that if not those of young simus, they 

 must belong to some unknown species of rhin- 

 oceros. " The horns of Rh. simus" said Sir 

 Andrew, " possess more of the above characters 

 than any others yet known."

 several of the " white two-horned rhinoceros " in 

 Karagweh, East Africa, and expressly says that

 Mr. Salt's trophies are doubtfully assigned to the white rhinoceros : 

 however, these interesting specimens agree perfectly with undoubted 

 simus horns.
