several migrating fishes ; of all such, the herring and pil- 

 chard take the most adventurous voyages ; places where 

 found in abundance, 128. Amazing propagation along our 

 coasts and rivers not proportionate to the quantities among 

 the Islands of the Indian Ocean; places where the spawn 

 is deposited ; doubts whether most fish come from the egg 

 completely formed ; growth of fishes; instance in the growth 

 of the mackarel ; all live upon each other in some state of 

 their existence ; of those in the ocean, of the spinous kinds, 

 the dorado the most voracious ; flying fishes chiefly sought 

 by the dorado? their warfare; opinion that all fish are na- 

 tives of the sea, founded upon their superior fecundity of 

 breeding twenty to one ; certainly fresh water fishes abate 

 of their courage and rapacity ; greediness of the sea-fish to 

 devour the bait prodigious/ compared with the manner it 

 is taken in fresh-water ; some fishes rendered so torpid in 

 the northern rivers as to be frozen up in the masses of ice, 

 and continue there several months, seemingly without life 

 or sensation, waiting the approach of a warmer sun to re- 

 store them to life and liberty ; each species of fish infested 

 with worms of different kinds ; most vivacious animals ; often 

 live upon substances poisonous to the more perfect classes 

 of animated nature ; numbers of fishes making poisonous 

 wounds, scarcely to be doubted ; some fishes being poison- 

 ous is notorious, the cause inscrutable ; the Philosophical 

 Transactions give an account of poisonous qualities of fish, 

 at New Providence ; all kinds, at different times, alike dan- 

 gerous ; the same species this day serving as nourishment, 

 the next found fatal ; speculations and conjectures to which 

 these poisonous qualities have given rise, 143, &c.

Fishing-frog, from its deformity called sea-devil ; conceit that 

 this fish uses its two long beards, or filaments, for fishing ; 

 llondelet says, that the bowels taken out, the body appears 

 transparent ; and, with a lighted candle in it, has a formida- 

 ble appearance ; fishermen have a great regard for this ugly 

 fish, as an enemy to the dog-fish ; when taken they set it at 

 liberty, v. 105.
