about three or four lines high towards the pedicle, 
and, ending, are loft. They flourifh and fpread at 
the bottom, forming an elliptical bladder, like an 
egg, flattened above and below, and rounded at the 
fides, being intirely empty : it is rough without, and 
very fmooth within. This egg, or oval bladder, is 
exa&ly round at the ends of the great diameter, but 
varies a little in the leflfer diameter, and forms it- 
felf like the body of a fiddle. The under part is a 
little flattened; and there is a hole, which is very 
conflderable, in the center of the two diameters. 
This hole is about an inch wide, and is quite round : 
it gives paflagb to the root, or pivot, which I fhall 
by and by mention : the edges appear to turn a little 
inward : and it is by this hole that the egg fills with 
fea- water. The whole fubftance of this bladder or 
egg is of a coriaceous matter, firm and tranfparent, 
and of a clear green ; nor can there be any fibres, 
either longitudinal or tranfverfe, obferved upon it. 
The vault at the top,- furmounted by the thighs, is 
as it were granulated ; but at the rounding of the 
egg it produces a kind of mamma , or little elevations, 
very round and cylindrical, intirely full ; of the fame 
nature and fubftance with the egg. 
In examining the under part of the egg, we found 
a fecond rank of thefe mamella , fomewhat longer 
than the firft, and at equal diftances from one an- 
other, in a circular line ; then a third yet longer ; 
then a fourth, which -at the extremities were bifur- 
cated ; and at laft a fifth rank, which divided into 
three, and fometimes into five, branches : thefe laft, 
placed round the hole, were wreathed inwards, and 
feveral were joined together, and only formed a fmall
