 the mouth, and out at the back of the head, to be 

 again sucked up as before. The liquid was not 

 absorbed by the hard surface of the table, and the 

 rhythmical movements were continued for the 

 space of two hours, and after the lapse of even 

 three hours the head resumed this action when 

 touched. 



One would like to know that a wasp, when 

 rolled helpless in a spider's web, or a spider found 

 from home by a wasp, and having his legs bitten 

 off one by one, has the same insensibility to pain 

 that the insect's head exhibited on the table, but 

 there is small evidence in support of such a wish. 



Combativeness not only prevails among animals 

 which can seriously hurt each other, but in those 

 that cannot do so. At the same time it must be 

 remembered that man himself is almost the only 

 animal that fights for the mere love of fighting, 

 and not for only some definite advantage. The 

 butterflies are not innocent of pugnacity, some of 

 them driving each other from favourite resorts. 

 The males only seem to do this, and those of but 

 few species. Are they clever enough to be jealous?
