when reptiles of great size literally overran the earth and cluttered up the sea. Many of these forms have been reconstructed from fossils found embedded in the rock strata. These are most amazing, grotesque and even terrifying and may be seen in any of the great museums. If a museum is not handy one may shiver with real thrills by going through the pages of a well illustrated text on geology.
Some such creature as one of these was Cetus,—according to the poets. Some authors think that the whole story of Andromeda is an allegory; others, that it may have been based, though somewhat lightly, upon a historical fact. Ancient authorities (Pliny, Josephus and others), claim that the bones of Cetus were brought from Joppa to Rome and there exhibited by M.

After having drawn the animal, however, with scales and claws, a mad, mad tail and sometimes even rows of teeth, the mapmaker becomes conservative and calls it "Cetus, the Whale."
As a constellation, Cetus first begins to appear in September but does not get fully above the horizon for almost four months.
