During the whole of this time only three other ants 

 came to the honey. 



On January 3, 1875, I placed some larvae in three 

 email porcelain saucers in a box 7 inches square attached 

 to one of my frame-nests of Lasius flavus (PI. I. 

 Fig. 2). The saucers were in a row 6 inches from the en- 

 trance to the frame, and 1 inch apart from one another. 



At 1.10 an ant came to the larvae in the cup which 



I will call No. 1, took a larva, and returned 



to the nest. 



1.24 she returned and took another.

 2.10 she went to the further saucer, No. 3. I 



took her up and put her to No. 1. She 



took a larva and returned. 

 2.24 she returned to cup No. 3. As there were 



only two larvae in this cup, I left her alone. 



She took one and returned. 

 2.31 she returned to cup No. 3 and took the 



last larva. 

 2.40 she came back to cup No. 3 and searched 



diligently, went away and wandered about 



for two minutes, then returned for another 



look, and at length at 2.50 went to cup 



No. 1 and took a larva. 

 3. came to cup 1 and took a larva.
