er two still thicker and longer. These four bodies are of a
cellular texture, and full of a milky fluid, which may be squeezed
out. This long twisted cord, r, to which the largest of the seminal
vessels is connected, this cord, I say, is doubtless the channel by
which the milky fluid issues. After several plications, it
terminates in a kind of bladder or fleshy sac, i. i. In different
males this part is of various length and flatness. By calling it the
_lenticular_ body, or the lentil, it receives a name descriptive of
the figure it presents in all males whose internal parts have
acquired consistency in spirit of wine. The body, l. i. is therefore
a lentil, a little thickened, of which one half, or nearly so, of
the circumference is edged along the outline by two chesnut coloured
scaly plates, e. i. A small white cord, the real edge of the lentil,
is visible, and separates them. This lentil is a little oblong, and,
for convenience, we shall ascribe two extremities to it, the
anterior and posterior. The anterior, l, next the head, is where the
canal, r, dividing the seminal vessels is inserted, and the opposite
part; i. next the anus, the posterior. The two scaly plates, e. i.
e. i, proceed from the vicinity of this last part, whence each
enlarges to cover part of the lentil. Under the broadest part of
each plate, there is a division formed by two soft points of unequal
length; the largest of which is on the circumference of the lentil.
Besides these two scaly plates, there are two others, n. n. of the
same colour, narrower, and fully one half shorter, each of which is
situated very near the preceding, and originates close to the origin
of that it accompanies, namely, at the posterior part of the lentil.
The rest of the lentil is white and membranaceous. From behind
proceeds a tube, k. a canal also white and membranaceous, but it is
difficult to judge of its diameter, for the membranes, of which it
consists, are evidently in folds. To one side of this pipe is
attached a fleshy part, p. somewhat pallet shaped, one side is
concave, and the edges plaited; the other side is convex. In certain
places the plaits rise and project from the rest of the outline, and
form a kind of rays; the pallet appears prettily figured. Though
lying with the concave side applied to the lentil, it is not fixed
