Underthese circumstances three antsran on to M; then two foundtheir way over the bridge a tom. Of the next ten ants, fivewent to M and five over a to next ten all went over the paper bridge a to m7. I then put the pillar and the larvae on the other sideof the original paper path at m, connected with themain path by a short bridge <z, taking for of a newpiece of paper, so that scent would be no guide. I leftthe little bridge a in its place. The ants went a*follows:—. 272 ANTS TO SOME EXTENT ) M 1 L To m 0 33 l 35 0 33 ? 33 0 53 •? 33 0 »3 33 1 33 * 33 0 33 J *• 33 0 W *? 33 0 » L 33 • 0 3f 3? 0 W 33 1 99 J 33 1 ft ^ 35 0 To M 0 3333 33333333333333333333 0000000 12 3 It seems clear, therefore, that though the ants didnot trust so much to their eyes as a man would havedone under similar circumstances, yet that they wereto some extent guided by sight. I then removed all the paper pathways and put theFig. 31. pillar to m. Of the first two ants which came to the table, the firstfound the pillar in five minutes,the second, after wandering aboutfor a quarter of an hour, gave thesearch up in despair, and wenthome. I then moved the pillarto m, and watched the next antthat came on to the table; she found it in a minute oi
