They are very sluggish intheir movements and may readily be re-moved from their resting-places by sud-denly thrusting a knife-blade under thefoot and prying them off. When thusdetached they have a habit of rolling upup into a ball and so remaining indefi-nitely; to prevent this they should beplaced at once in a jar of sea-water,where they will resume their naturalposition. For preservation as cabinetspecimens, chitons should be tied downbetween two boards or flat substances, to hold them firmly ex-tended until dried; otherwise they are apt to contract out ofshape.
