her into a small cup containing a number of larvae. She worked 

 continuously till half-past seven in the evening, -when I left off 

 watching. During that time she had made more than ninety 

 journeys, carrying each time a larva to the nest. During tlie 

 ■whole time not a single other ant came to the larvse. 



Again on the 7th Feb. I watched two ants in the same manner. 

 At 7 A.M. I put some larvse in the small china cups. Up to 8 no 

 ants had come to them. Soon after 8 I put two marked ants, 

 neither of them being the same as these whose movements are 

 above recorded. They were then watched until a quarter to eight 

 in the evening, during which time one of them had made twenty- 

 six journeys, carrying off a larva each time ; the other forty-two. 

 During this period of about eleven hours, two strange ants had 

 come to the cujj at which these were working, and the same 

 number to one of the other cups. 



None of these ants, therefore, though they had found a large 

 number of larvse, more than they could carry in a whole day, sum- 

 moned any other to their assistance.
