S24) THE ZIMB. 



sands of Atbara ; for when once attacked by 

 this fly, his body, head, and legs break out 

 into large bosses, which swell, break, and 

 putrify, to the certain destruction of the 

 creature. Even the elephant and rhinoceros, 

 who, by reason of their enormous bulk, and 

 the vast quantity of food and water they 

 daily need, cannot shift to desert and dry 

 places as the season requires, are obliged to 

 roll themselves in mud and mire, which, 

 when, dry, coats them over like armour, and 

 enables them to stand their ground against 

 this winged assassin ; yet have I found some 

 of these tubercles upon almost every ele- 

 phant and rhinoceros that I have seen, and 

 attribute them to this cause." 



There are twelve species of this insect.
