There is a nerve, of the bignels of a horfe-hair, all black, hard 
to break, with knots at proper intervals, which begins at the 
mautli of the animal, and pafles over the parts, that jerve for ge- 
neration in the male^ it is faftened m a ftreight line all along the 
upper part of the gut, terminates at the little circle in the end 
of the tail, and in its way lends out branches from each knot 
both to the right and left j it is very probable, that by this canal, 
the animal Ipirits run plentifully, which give fo great brifknefs 
to this reptile, and cauie ittolwim {o fwiftly, and luck with fuch 
greedinefs. The leech is hermaphrodite 5 the parts of the male 
deftined for generation are placed where the neck fhould be 5 the 
yard, which is above two inches long, is white, round, hollow 
and griflly ; a part of the yard, which is always in the body, i» 
a /heath, about 17 lines of an inch in length, and as big as a 
Imall bird's quill, covered with a fine membrane, which fallens it 
ftrongly to the belly, round about a fmall hole given the leech 
for exerting its '■Penis at plealure, and not for breathing as the 
ancients tliought^ the other part of the yard, which comes out 
9 or 10 lines of an inch, is of the bignefs of a fewing thread, and 
its extremity, for the length of two Imes, is bigger than the reft 5 
all the yard is hollow, and hath in its cavity a white mufcle, as 
big as a hair, faftened only to the root and head, all the reft be- 
ing at liberty 3 it is by this mulcle that the animal retrafts the 
^jPenis into its llieath, which any one may try, by cutting it at 
the root, and drawing out this mufcle with his nails j on every fide 
of the root of the yard there is a fmall white flat oval web, about 
two or three lines in length, relembling linall guts, twifted iibout 
with a cartilaginous bocly, as big as a double thread, and two 
lines in length, faftened to the root of the yard, which probably 
contains the prolific mattery a little above the root of the yard, 
between thcle two webs, there is a fmall griftly globules, vvhi.h 
M. Toupan takes to be a terticle, two inches long, and which 
is white, hard, hollow, round, oval, fliarp, internally covered 
with a membrane, wrinkled and full of a milky liquor j at the 
head of this globule there is a fmall web, like to an EpididymiSy 
whole little canal, of the fame piece therewith, creeps over the 
globule, and is faftened at its pointy and above the Epididymis 
there are two glands exa£}ly round, each as big as a millet iced 5 
all along every fide of the iniellinc, there is a white canal, or 
Ovariiwiy of the bignefs of a fmall twifted thread, and folded a
