10 zoo LOOT 



The sense-organs of the cricket are not so complex as our 

 own. Organs of taste have been found in tlie mouth, and it is 

 certain that insects can tell one kind of food from another. 

 The sense of hearing is found among manj- insects, as the loud 

 sounds made by some of them indicate. Indeed, in the grass- 

 hopper there is a meml^rane on the first segment of the aljdo- 

 men which acts like the membrane of the drum of our ear. 

 Finally, the organ of sight is well developed. The eyes of the 

 cricket are a pair of large areas on the head made up of numer- 

 ous little eyes, each of which sees a part of the field of view. 

 Consequently the whole eye throws on the sensitive nerve- 

 endings a series of little pictures which together, like the blocks 

 of a mosaic, make up the whole picture of what is before the 

 insect.
