Salamander \Sal"a*man`der\, n. [F. salamandre, L. salamandra,
   Gr. ?; cf. Per. samander, samandel.]
   1. (Zool.) Any one of numerous species of Urodela, belonging
      to Salamandra, Amblystoma, Plethodon, and various
      allied genera, especially those that are more or less
      terrestrial in their habits.
      [1913 Webster]

   Note: The salamanders have, like lizards, an elongated body,
         four feet, and a long tail, but are destitute of
         scales. They are true Amphibia, related to the frogs.
         Formerly, it was a superstition that the salamander
         could live in fire without harm, and even extinguish it
         by the natural coldness of its body.
         [1913 Webster]

               I have maintained that salamander of yours with
               fire any time this two and thirty years. --Shak.
         [1913 Webster]

               Whereas it is commonly said that a salamander
               extinguisheth fire, we have found by experience
               that on hot coals, it dieth immediately. --Sir T.
                                                  Browne.

SALAMANDER, n.  Originally a reptile inhabiting fire; later, an
anthropomorphous immortal, but still a pyrophile.  Salamanders are now
believed to be extinct, the last one of which we have an account
having been seen in Carcassonne by the Abbe Belloc, who exorcised it
with a bucket of holy water.
