burrow, that the broader end was not well adapted for this purpose—even in this case a large proportion would probably have had their basal ends dirtied. We may therefore infer—improbable as is the inference—that worms are able by some means to judge which is the best end by which to draw triangles of paper into their burrows.
The per centage results of the foregoing observations on the manner in which worms draw various kinds of objects into the mouths of their burrows may be abridged as follows:—
| Nature of Object. | Drawn into the burrows, by or near the apex. | Drawn in, by or near the middle. | Drawn in, by or near the base. |
| Leaves of various kinds | 80 | 11 | 9 |
| of the Lime, basal margin of blade broad, apex acuminated | 79 | 17 | 4 |
| of a Laburnum, basal part of blade as narrow as, or sometimes little narrower than the apical part. | 63 | 10 | 27 |
| of the Rhododendron, basal part of blade often narrower than the apical part. | 34 | . . | 66 |
| of Pine-trees, consisting of two needles arising from a common base | . . | . . | 100 |
