in regard to either Sex, though it may be perfedly of 
both Sexes fo far as regards Generation. 
Under this Idea of an Hermaphrodite^ I may ven- 
ture to fay, the Lobfter referred to my Examination 
is truly one \ and, if fplit from Head to Tail, is Female 
on the right Side, and Male on the left Side. 
In Order to illuftrate this, I lliall give a (hort Ac- 
count of the Strudure of the male and female Lob- 
fter, fo far as relates to the Difference between the two 
Sexes, and then proceed to ftiew in what Manner 
they were combined in the Subjed before you. 
It has already been obferved that the Lobfter, both 
male and female, has all the Parts of Generation double, 
except that the female has one PalTage only, through 
which it is probable the Ova are emitted out of the 
Trunk, in Order to be affixed to the fmall Appendages 
under the Tail. 
The Penis of the male Lobfter arifes from the Te- 
fticle, and is no more than a Continuation of the Fas 
deferens ; it is refleded and retored once, after which 
it grows thicker, as to its Subftance (probably form- 
ing a ) and terminates, not in the 
laft Leg but one, as tVillis^ in his Treatife de Hnimd 
Brutortm has obferved, but at a fmall perforated Tu- 
bercle in the' firft Bone of the laft Leg. See Fig. 
the A A, the tvoo Penes. 
Between the two laft Legs and the two Legs above 
them are two Proceffies, which, from their refembling 
the Nympho of Women, 1 (hall term Nymph a form 
Proceftes. Thefe ProcelTes are covered with Hair, 
and unite at their Bafes without leaving any Paftage.
