244' SIE JOHN LUBBOCK ON THE HABITS OP ANTS. 



Fig. 6. 



Diagram representing three tracks of an ant in another experiment. 

 A, the fii-st position of pencil and the food, towards which and from the base- 

 line of nest 1 and 2 lead by nearly direct broadish white lines to A. When the 

 latter was removed to B the ant, in its effort to reach this, pursued the narrow

 direction. 



I may here note that the diagrams figs. 2-7 are careful reduc- 

 tions of large tracings made during the experiments. Though 

 not absolutely correct in every minute detail of contour, they are 

 exact for all practical purposes. As the ants pursued their 

 way, pencil-markings in certain instances, and coloured lines 

 in others, were made so as to follow consecutively the paths 

 pursued. 



Hearing. 



As regards their sense of hearing, I have in my previous paper

 ing an ant which was standing quietly, I have over and over again 

 made the loudest and most shrill noises I could — using a penny 

 pipe, a dog-whistle, a violin, as well as the most piercing and 

 startling sounds I could produce with my own voice, but without
