Thus, then, the general results were that the ants 

 removed forty-one friends and fifty-two strangers. Of 

 the friends, thirty-two were carried into the nest and 

 nine were thrown into the water. Of the strangers, on 

 the contrary, forty-three were thrown into the water ; 

 only nine were taken into the nest, and seven of these 

 were shortly afterwards brought out again and thrown 

 away. Indeed, I fully believe that the other two were 

 treated in the same manner, though we could not satisfy 

 ourselves of the fact. But it was only by very close 

 observation that the seven were detected, and the other 

 two may well have escaped notice. 



It seems clear, therefore, that even in a condition 

 of insensibility these ants were recognised by their 

 friends.
