rings, and its tending to a point at the end 5 and opening it, there 
was found within two firings aa^ proceeding from the neck, and 
floating in the liquor 3 whole ufe may be to convey into the fto- 
mach or bladder the moifture or nourifhrrient, which the worm, 
by protruding its neck attra6ts from the external membrane 5 and 
that this bladder is the ftomach, will appear lefs uiirealbnable, if 
we confider how prodigioufly large the ftomach is in fome infers 
in proportion to the other parts of the body 5 in a leech you may 
oblerve not a (ingle, but above 20 llomachs, which empty out of 
one into another, and run the whole length of the body ^ and 
what Malpighi obferves of the filk-worm, that it would devour 
in one day as much as the weight of its whole body, holds more 
truly of a leech, that will do as much at a meal: Some will 
poffibly be more inclined to think, that the whole is but an egg, 
or embrio of another infect, and that this bladder is the Amtjion^ 
and the external coat that includes it in the Chorion -^ but for- 
tnerly, in difle^-ing a rotten fheep, wherein Dr. ^fon foijnd 
many of theie Hydatides., and opening feveral of them, he ob- 
lerved the fame ftrufture in all ; and doubtlefs had they been real 
embrios, iome of them would have come nearer to a flate of per- 
fedion than others 5 he therefore thinks thefe Hydatides to be a Ibrt 
cf worms or iuk^s fui Generis , and becaufe they contain fo much 
water, and are ufually to be met with in rotten ilieep which are 
hydropical, Dr. 7yf on calls them Lumhrici Hydrapici : But he 
does not think that all the bladders to be found in morbid bodies, 
are cf this fort 3 for in Ibme he did not oblerve this neck and 
firufture of parts, but only a tranfparent bladder, filled with a 
Lyriipha: Thus, upon opening the right fide of a patient, a little 
below her fhort ribs, there iffued out a great deal of limpid 
water, and tooether with it a great many Hydatides to the number 
of 5005 moft of which were entire ana filled with limpid water, 
the films of others, that were too large for the orifice were bro- 
ken, but in none of them could he obferve the neck 5 which made 
him think them ditferent from the prefent fubje6^, as are likewiie 
thole he frequently met with in the Ovaria or telticles of women, 
who have died hydropical, which he only takes to be the eggs, 
contained therein, fvvelled to that bigneis by a great flux of hu- 
mpurs into them.
