437. It Is remarkable that while a great number of writers have fully discussed 

 the uses and curious anatomy of the elephant s trunk, they have been almost siient 

 as to the wse of the tusks. It is obvious, however, that these prominent and 

 ponderous weapons must be of material consequence in t&e economy of the aniraal 9 

 existence. In Partington s &quot; Cyclopaedia &quot; we find the following speculations np &amp;gt;B 

 Hie subject; 



In the living elephants of both varieties the tusks are either nearly straigat 

 9t curved upwards ; or if their direction be nearly that of the line of the face they 

 are inclined forward at the points-. In the fossil elephant, on the other hand, (at 

 least in all the specimens which have been found,) the curvature of the tusks is the 

 &quot;the other way, or downwards. What may be the use of this difference of structure 

 it is not easy to say, because we know nothing of the habits of the extinct elephant, 

 and very little of what the state of the country may have been when it was alive ; 

 but as tfze tusks in it are so constructed as that they might act as hooks in pulling 

 down substances higher than itself, and as it is probable that the northern marshes 

 were at that time covered with tree ferns, and those other palm-like plants, of 

 which the remains are abundant in the fossil state, though not a vestige of those 

 plants now appears on the surface of the same regions, we may perhaps venture to 

 conclude that such tusks had been employed in pulling* down the fronds of the 

 plants in order that the animal might feed upon them.* 



The elephant rarely uses b trunk as a weapon, but his tusks- enable him not 

 enly to clear his way through the thick forests m which he lives, by rooting up 

 small trees and tearing down cross branches, in doing which service they effectually 

 protect his face and proboscis from injury ; but they qualify him for warding ofi 

 the attacks of the wily tiger and the furious rhinoceros, often securing him the 

 victory by one blow, wMch transfixes the assailant to the earth. 



438. Why are the eyes of the elephant remarkably small? 



By their smallness they are more easily protected fron; &amp;gt;njury 

 while the animal is engaged in breaking down branches &amp;gt;f trees. 

 And they are also rendered more secure from the attacks of 

 insects which, in the geographical range of the elephant, are 

 exceedingly troublesome. 



The eye is uot only protected by the comparative smallnesa 

 of its size, bat it is provided with a nictating membrane, by 

 which the elephant is enabled to free it from all accidental 

 fragments that may fall upon it. This membrane, which is 

 limilar to that possessed by birds, is not the ordinary eye-iiti,
