Show Tbe I'olnon ofToads and Salamandera A recent microscopical study by Herr Schultz has revealed two kinds of glands mucus and poison in the skin of toads and salamanders, The mucus glands are numerous over the whole body; but the poison glands are on the back and limbs, in groups about I the ears, aud, in the salamander, at the angle of the jaw. The mucus glands are spherical, ond 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 the 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 less promptly, and spar, ingly in drops. |
