750 PISCES— DORADO. ..SWORD FISH. 



was long a matter of doubt, but appears now to be an ascertained fact. M. 

 GeofTroy, when near Malta, in 1798, saw two of the pilot fish lead a shark 

 to a piece of bacon, which a seaman had let down by a line and hook. 



THE DORY, OR DORADO. 2 



The form of this fish is very disgusting. Its body is oval, and much 

 compressed at the sides. Its snout is long, and its mouth is wide. The 

 first back fin consists of ten spiny rays, with long filaments ; the second of 

 twenty-four soft rays. The tail is round at the end. The color of the body 

 is olive, varied with light blue and white ; while living, it has the appear- 

 ance of gilding, whence its name Doree (gilt). It is found in the North 

 sea, the British channel, the Atlantic, and the Mediterranean. 



THE SWORD FISHi 



Is very common in the Mediterranean, and is much esteemed for food by the 

 Sicilians, who consider it as equal to the sturgeon. It is also found on the 

 coasts of America. It grows to a very large size, upwards of twenty feet in 

 length. It is of a long and rounded body, largest near the head, and taper- 

 ing by degrees to the tail. The skin is rough, the back black, and the belly 

 white. It has one fin on the back, running almost its whole length. It 

 has one pair of fins also at the gills. But the most remarkable part of this 

 fish is the snout, which, iji the upper jaw, runs out in the figure of a sword, 

 sometimes to the length of three feet, and is of a substance like a coarse 

 kind of ivory. The under jaw is much shorter.
