There are T ’ape-worms I ike wife in the Bow¬ 
els of a Turbut , tho’ fhorter than thofe in 
Eels , and with a Head not quite the fame. 
They are fixed to the Guts by a Kind of 
Hooks which they have in their Mouths, 
and are not to be got off, but by holding the 
Tail with one Hand, and feparating the 
Head from the Inteflines with a Needle. 
Having found thefe Worms in the Xntef- 
tines of Fifhes, let us now confider how 
they could get there. And it is probable they 
are naturally Water Animals, whofe Eggs 
or young-ones getting into the Stomach with 
the Water or the Food, become hatched or 
nourished there. In the fame Manner they 
may alfo be introduced into the Stomach of 
other Animals: and their Difference of Size 
in one or the other may arife from the dif¬ 
ferent Degrees of Heat, and the Kinds of 
Nourishment they meet with.—Three other 
^orts of Worms are alfo found in the Intef- 
tines of Eels . Carp are likewife fubjed to 
Worms which make them very lean, and fo 
is the Trout .—There are two Sorts of white 
Worms in the Whiting; and the Microfcope 
may difcover them perhaps in every other 
Kind of Fifh : nor can we wonder at it, 
v when we refled: how liable Fifhes muff be 
to fwallow the Eggs or young-ones of what- 
ever Infeds are Inhabitants of the Waters.
