 all Cetaceans which are too small to be dignified with the title of 

 "Whales," such as the various Dolphins.

{Delphinus delphis) 



This celebrated animal is nearly related to the Porpoise, but is much 

 larger, measuring from five to eight feet ; it is also more elegantly 

 formed, being a perfect model of symmetry, with the jaws prolonged 

 into a narrow beak-like muzzle clearly marked off from the forehead-

 which is perhaps the jolliest beast alive. When the school catch sight

 fancy swimming in the meantime. Thus, I have seen them jump out 

 of the water, and turn on their backs in the air right in front of the 

 ship's stem, heedless of the risk they were running. The stroke of
