228 SIR JOHN LTJBBOCK ON THE HABITS OF ANTS. 



At 3.15 a friend to water. 

 3.16 a friend to nest. 

 3.22 a stranger to water. 

 3.25 



At 3.25 a friend to nest, 

 3.35 a stranger to water. 

 3.50 a friend to nest. 

 3.50 



All these ants appeared quite insensible ; 16 friends were then 

 taken to tlie nest and 5 to the water, while of the strangers only 

 3 were taken to the nest, while 15 were thrown into the water. 

 Moreover, as in the preceding observation, even the three stran- 

 gers which were at first taken to the nest were soon brought out 

 again and thrown away ; while this was not the case with any of the 

 friends as far as we could ascertain, though we searched diligently 

 for them also. In this case also all the intoxicated ants were 

 motionless and apparently insensible. 



Jan. 15. Eepeated the same experiment, beginning at 12.20. 

 Up to 7 P.M. not one of the intoxicated ants had been moved. At 

 8.20 we found a stranger in the water, at 9.30 another, and at the 

 following morning a third. The others were untouched. 



Jan. 17. Eepeated the same experiment, beginning at 11.30. 

 At 12 a friend was carried to the nest. 



12.20 a stranger was carried to the water. 

 12.31! a friend was carried to the nest. 

 12.40 a stranger was carried to the water. 

 12.45 a friend was carried to the nest.

(Stopped observing till 2.)

 2.30 „ „ nest. 



4.30 a friend „ „ 



6.20 a stranger was carried to the water. 



6.35 „ „ „ 



Thus, then, the general results were that the ants removed 

 thirty-eight friends and forty strangers. Of the friends, twenty- 

 seven were carried into the nest and seven were thrown into the 

 water. Of the strangers, on the contrary, thirty 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 observation.
