by means of the varied action of the lids. Man is able 

 to convey a great deal of expression by the action of a 

 single eyelid, and it is reasonable to suppose that the 

 alligator would not have been provided with a triple 

 eyelid had it not been able to utilise these coverings in 

 a very marked manner. It is strange and somewhat un- 

 fortunate that this peculiarity should not have been made 

 the subject of much further investigation and research by 

 scientific men than has hitherto been bestowed upon it. It 

 is evident indeed that we have still much to learn concerning 

 the crocodile ; and in view of its early disappearance, it is 

 to be hoped that the matter will speedily be taken in hand 

 by some trained investigator.
