gures made by his ingenious Hand; both Natural as they 
appeared to the naked Eye, and what they were difcover'd 
to be by the Microfcope. 
Fig. i. Reprefents one ofthefe watory Bladders in its 
natural bigneis inclofed in its outward Membrane or Cho- 
tion^ its fti ape was almoft round, only flatted as a drop 
of Quickfilver will be by lying upon a folid. (a) fhews 
th'e Neck, leen through the Membrane, which in 
Fig. x.is more plainly reprefented, ("the outward Mem- 
bfane being taken off) but as appearing to the naked Eye ; 
where we may obferve an open Orifice at the Extream 
-of it, and that it is made up of circular Rings or Incifures ; 
which in 
Fig. 3* being viewed by a Microfcope, do more evident- 
ly difcover themfelves: This part is granulated with an 
abundance of fine Eminences all over. The Orifice at

Fig, 4. Is reprefented the Neck of this Worm drawn 
out its whole length and magnified : Where way be ob- 
ferved the leffening of the Rings, and its tending to a 
point at the end. And having opened it 5 within we found 
two fmall ftrings ( a a) proceeding from the Neck and 
floating in the Liquor. 
What thefe two Strings may be, is hard pofitively to 
aUert: Leaving others to their own conje&ures, I (hall 
deliver mine; That this Worm by protruding its Neck, 
fucks from the outward Membrane (which involves it, 
and is furniflied with Blood- Veflcls,) the moifture or nou- 
rilhment which is conveyed by thefe two Strings or Pipes 
into the Stomach or Bladder, and from whence, as there 
is occafion^ it may be fupplied for the nouriftiing the whole 
Body of the Worm again ; for I am apt to believe, this 
Bladder is but the Stomach of the Worm, Which will ap-
