TONGUES WHICH CARRY TEETH.
You've heard of folks with biting tongues, I dare say, and very disagreeable they are, no doubt, though, of course, they do not actually bite with their tongues. However, there really is an unpleasant fellow whose tongue carries twenty-six thousand eight hundred teeth! A capital one for biting, you'd suppose. He is nothing but a slug, though, and his army of teeth only scrape, not bite, I'm told. Then, too, there is a sort of cousin of his, a periwinkle, who has a long ribbon-like tongue, armed with six hundred crosswise rows of hooks, about seven in a row.
You can make sure of these surprising facts, my dears, with the aid of patience and a microscope.
