Show 1 he I'uIkoii nl ! ond-mill Niilaiiinndera A recent microscopical study by Ilerr Sfehultz has revealed two kinds of glands mucus and poison in the skin of toads and salamanders, The mucus glands tire numerous over the wholo body; but tho poison glands are on tho back and limbs, in groups about the ears, and, in tho salamander, at the angle of the jaw. The mucus glands are spherical, and appear clear and glassy: while the poison glands are oval, much larger, and have a dark granular look. The mucus has no special smell, nor bitter or acid tastes. On stimulating tho poison glands electrically, the corrosive liquid is spurted out by the salamander in a fine jet, often a foot long, but from the toad it exudes les3 promptly, and spar, ingly in drops. |
