The galley-worms (Julus) (fig. 64), large, black-ish, cylindrical millipeds found under stones and logsand leaves and in loose soil, are familiar forms. Theycrawl slowly and when disturbed curl up and emit a mal- odorous fluid. They can easily bekept alive in shallow glass vesselswith a layer of earth in the bottom,and their habits and life-history maythus be studied. They should befed sliced apples, green leaves, grass,strawberries, fresh ears of corn, are not poisonous and maybe handled with impunity. They laytheir eggs in little spherical cells ornests in the ground. An Englishspecies of which the life-history hasbeen studied lays from 60 to 100eggs at a time. The eggs of thisspecies hatch in about twelve lithobians and centipeds areflattened
