LEVIATHANn. An enormous aquatic animal mentioned by Job. Some suppose it to have been the whale, but that distinguished ichthyologer, Dr. Jordan, of Stanford University, maintains with considerable heat that it was a species of gigantic Tadpole (Thaddeus Polandensis) or Polliwig — Maria pseudo-hirsuta. For an exhaustive description and history of the Tadpole consult the famous monograph of Jane Porter, Thaddeus of Warsaw.
