with few larvae made 7 journeys and brought 3 friends. 
The one with many larve made 19 journeys and brought 
6 friends. 
Experiment 9.—Time occupied, 1 hour. The ant 
with few larvae made 11 journeys and brought 1 friend. 
The one with many larve made 15 journeys and 
brought 13 friends. 
Experiment 10.—I now reversed the glasses, the 
same two ants being under observation ; so that the ant 
which in the previous observation had few larve, now 
consequently had many, and vice versa. Time occupied 
2 hours. The ant with few larve made 21 journeys 
and brought 1 friend. The one with many larve made 
$2 journeys and brought 20 friends. These two experi- 
ments are, I think, very striking.

ELxpervment 15.—Time occupied, 43 hours. The 
ant with few larvee made 40 journeys and brought 10

dur:ng the last hour and a half she only brought 1
