THE BLAAUWBOK 57 



possibly be confounded. Apparently, the animal 

 was shot in the prime of life : the horns are 

 neither worn nor splintered : the sutures of the 

 skull are unobliterated, and the teeth are in 

 excellent condition. Unfortunately the premaxillae 

 and lower jaw have been lost. 



The following horn measurements of this unique 

 example may be compared with those of horns 

 attached to skin-specimens at Leyden, Paris, &c. : 



Length of left horn 1 over anterior curve, 2 2 in. 



Circumference at base, 6in. 



Minimum divergence, i-Mn. 



No. of rings : 20 (left horn), 21 (right horn). 



To recapitulate : 



The horns attached to the male frontlet in the 

 National Collection are 20 inches long : those of 

 the bull at Paris, tape 21} inches: of the bull at 

 Leyden a record measurement 24! inches. The 

 horns of the cow at Vienna reach 2O| inches, 

 and those of the cow in the Royal College of 

 Surgeons' Museum are 22 and 21 inches respec- 

 tively. Thus the various measurements show a 

 certain relationship to each other : had the speci- 

 mens from which they have been taken belonged 

 merely to a haphazard series of different animals 

 instead of to one definite species, they would not 

 have exhibited this agreement. The dimensions 



i The right horn has about one inch of the tip missing, hence the 

 original distance between the tips could not be taken.
