belly, which the birds cannot get at easily. I have found 

 various species of these parasites upon them, and, among 

 others, Amblyoma aurcuin, Ambl. kedr&um, Ambl. 

 deiiuw, and, in very considerable numbers, Dermacentor 

 rhinocerotis. 



Very probably the rhinoceros is infested also by another 

 kind of tick, unknown until discovered by myself. Of 

 all these that I have named, however, the Dermacentor 

 rhinocerotis is the only one that is peculiar to the 

 rhinoceros. 



I have never actually encountered more than four 

 rhinoceroses at a time, though I have often seen as many 

 as eight together. The manner in which they find their 

 way to their drinking-places, often involving a journey of 

 several hours, is wonderful. They select several spots 

 on which to drop their dung, which they then scatter 

 about with their hind-legs. In this fashion it is they 

 set about making their wide pathways over the velt. 

 Doubtless these heaps of dung serve as marks, which help 

 them to find their way back in the direction from which 

 they have come. 



The shape of rhinoceros-horns varies greatly. The 

 horns of the cows are long, and always thinner than 

 those of the bulls. Sometimes the horns are flat, like 

 swords. You find this sometimes even in those regions 

 in which round-shaped horns are the general rule. Now 

 and again the horns of very old cow rhinoceroses grow 

 to the length of nearly five feet. 



In a very few rare cases more than two, sometimes 

 as many as five, horns are to be found on the African
