affected by being very gently breathed on, even when I had some chewed tobacco in my mouth, or a little cotton-woll, on which a few drops of perfume or of acetic acid had been placed.) We must suppose that they can taste; & they apparently like cabbage better than other leaves, but it is difficult to judge on this head from their omnivorous habits. One sense alone is highly developed that of touch, for they instantly perceived a very slight tap on the outside of the pots, or on the table on which the pots stood, though the vibration had to be transmitted though somewhat loose damp earth. They also readily perceived a slight puff of air, In such cases they show their perception by withdrawing into their holes with extraordinary, flash-like, rapidity. Or as on [pencil insertion largely illeg] At night the anterior extremity fo the body, which is much more extensive than the posterior part, is eventually moved in all directions & senses as an organ of touch. With so few senses & with so many enemies it seems

Cabbage-leaves, especially when a little decayed are much liked by worms; but when these & horse-radish leaves (which are also liked) were placed together into those of the onion, the latter were always & manifestly preferred. Cabbage, Leaves of the cabbage, lime-tree, Ampelopis, parsnip & cle celery were left on the pots likewise given together & those of the celery were preferred first gnawed & eaten. Again But when leaves of cabbage, turnip, beet, celery, wild cherry & t carrots were given together, the two latter kinds, especially those of the carrot, were preferred to all the others, including even those of celery. It was also manifestly by repeated trial that after many trials that the leaves of the wild cherry were greatly preferred to those of the lime-tree & hazel hazel (Corylus). (According to Mr Bridgman the 1/2-decayed leaves of Phloxverna are particularly liked by worms.*
Pieces of the Leaves of cabbage, turnip, horse-radish & onion were left on the pots during 22 days, & were all immediately attacked & had to be renewed; but the same time removed what [illeg]; to gather with leaves of some other probably kinds of [illeg] lime, namely the during the whole of this time leaves of an Artemisia & of the culinary thyme, sage & mint, mingled with none of the the others above leaves, were [illeg] by the worms quite neglected, except those of mint, which were occasionally & very slightly nibbled. These latter four kinds [3 words illeg] all strong taste, but so have the four first mentioned kinds; & we can account for the wide difference in the the manner in which they were tasted by worms can be accounted for only by the difference in the of strong taste.) to that of [words illeg] result must be attributed to a difference in their tastes.)
