I then put some specimens of Lasius niger tothe larvae, and soon a large number of ants were en-gaged in carrying off the larvae. When this had con-tinued for about three hours, I raised D ^ of an inchabove a. The ants kept on coming and tried hard toreach down from d to a, which was only just out oftheir reach. Two or three, in leaning over, lost theirfoothold and dropped into the larvae; but this wasobviously an accident; and after a while they all gaveup their efforts, and went away, losing their prize, inspite of most earnest efforts, rather than drop -j^ of an inch. Fig. At the moment when the separation was made therewere fifteen ants on the larvae. These could, of course,have returned if one had stood still and allowed theothers to get on its back. This, however, did notoccur to them; nor did they think of letting themselvesdrop from the bottom of the paper on to the or three, indeed, fell down, I have no doubt, byaccident; but the remainder wandered about, until atlength most of them got into the water.
