The object of my invention is to effect the removal of worms from the system, without employing medicines, and thereby causing much injury.

The trap is baited by taking off the cover B, of the exterior box, and filling the interior box with the bait which may consist of any nutritious substance. The interior box D, is then pushed down until the stud F, catches between the teeth of the opening E, and holds it with the openings E, and C, opposite each other, the points of the teeth being then below the lower edge of the opening C. The trap having the cord H, attached to a ring I, on the lid is then swallowed. The worm, in inserting its head at the opening E, and eating the bait, will so far disturb the inner box as to work it free of the stud F, when the box will be forced upward by the spring G, and the worm caught behind the head, between the serrated lower edge of the opening in the interior box; and the upper edge of the opening in the exterior box. The trap and the worm may then be drawn from the stomach, by the cord H.
