port continued in rapid progressiov, un- 
til there arrived, by hundreds, the re- 
cruits, with their living burthens, and 
there remained no longer any ants in the 
superior part of the ruche. When 1} 
ceased warming the frame, the ants re- 
gained the glass, but as often as I ap-

ceeding again took place. * 
* That ants will occasionally avail themselves of 
the heat supplied by other sources besides the sun, 
is sufficiently evident from what follows: ‘ M. 
Reaumur, in refuting the common notion of ants 
being injurious to bees, tells us, that societies of 
the former often saved themselves the trouble of 
removing the larve, &c. from place to place, by 
establishing their colonies between the exterior 
wooden shutters and panes of his glass hives, where, 
owing to the latter substance being a tolerably 
good conductor for heat, their progeny was, at all 
times, and without any necessity of changing their 
situation, in a constant, equable, and _ sufficient 
temperature. Bonnet observed the same fact. He 
found that a society of ants had piled up their 
young to the height of several inches, between the 
flannel-lined case of his glass hives and the glass. 
When disturbed they ran away with them, but al- 
ways replaced them. I am persuaded that, after 
duly considering these facts, you will agree with
