104 THE RHINOCEROS. 



two*. But it is not equally certain that this 

 variety is conftant, and depends on the climate 

 of Africa or India , or that this difference is alone 

 fufjicient to conilitute two diftmct fpecies. It 

 appears that the rhinocerofes, with one horn, 

 have this excrefcence always loneer than thofe 

 with two. There are Tingle horns of three and 

 ilf, and perhaps of above four feet in length, 

 by fix or feven inches diameter at the bafe. Some 

 double horns are two feet long f. Thefe horns 

 are commonly of a brown or olive colour ; 

 though there are inftances of their being gray, 

 and even white. They have only a flight con- 

 cavity in form of a cup under the bafe, by which 

 they are fixed to the (kin of the nofe. The reft 

 of the horn is folid and harder than common 

 horn. It is with this weapon that the rhinoce-

* Kolben averts pofttively, and as if he had been an eye- 

 witnefs, that the firft horn of the rhinoceros is upon the nofe, 

 aud the fecond upon the front, in a right line with the firft ; 

 that the latter, which is brown, never exceeds two feet in, 

 length ; and that the fecond is yellow, and feldom longer 

 than fix inches; Defcript. du Cap. da Bonne Efperance, torn. 3. 

 p. 17. — But we have already mentioned double horns, the 

 fecond differing very little from the firft, which was two 

 feet long, and both were of the fame colour. Befides, it 

 appears to be certain, that they are never at fuch a diftance 

 from each other, as this author has placed them ; for the 

 bafis of the two horns, preferved in the cabinet of Sir Hans 

 Sloane, were not three inches afnnder.
