friend. However, [ think it fair to record the observa- 
tion. 
The ant with many larvee made 47 journeys and 
brought 1 friend. 
Expervment 16.—Time, 44 hours. The ant with 
few larvee made 20 journeys and brought 1 friend. She 
did not return after the first 2 hours. The other ant 
made 53 journeys and only brought 2 friends. This 
latter was the same one as in the previous experiment, 
when, however, she had the glass with only two or three 
larvee. 
Experiment 17.—Time, 1 hour. The ant with few 
larvee made 6 journeys and brought no friend. The 
one with many larvee made 11 journeys and brought 12 
friends. 
Experiment 18.—Time, 14 hour. The ant with 
few larvae made 25 journeys and brought four friends. 
The one with many larvee made 20 journeys and brought 
15 friends. 
Experiment 19.—Time, 44 hours. The ant with 
few larvee made 74 journeys and brought no less than 
27 friends. This is quite in opposition to the other 
observations ; and I cannot account for it. She was 
the ant who brought 15 friends in the previous experi- 
ment, and it certainly looks as if some ants were more 
influential than others. The ant with many larve 
made 71 journeys and only brought 7 friends. 
Experiment 20.—Time, 2 hours. Theant with few 
larvee made 35 journeys and brought 4 friends. The 
one with many larve made 34 journeys and brought 3 
friends. 
Experiment 21.—I now transposed the two glasses. 
Time, 14 hour. The ant with few larve made 15 
journeys and brought no friends. The other made 35 
journeys and brought 21 friends. 
Experiment 22.—I now transposed the glasses 
again, Time, 2 hours. The ant with mary larvee made
