 2 III,  1 |            coalescing into a single duct above the outlet of the
 3 III,  1 |             two testicles extends a duct, and, as in the case of
 4 III,  1 |            the testicle itself is a duct, thicker and more sinewy
 5 III,  1 |             other just alluded to-a duct that bends back again at
 6 III,  1 |             front at the penis. The duct that bends back again and

10 III,  1 |        starting below from a single duct extends continuously on
11 III,  1 |            of thus being a separate duct on each side of the spine,
12  IV,  1 |             males. The males have a duct in under the oesophagus,
13  IV,  2 |           Again, the crawfish has a duct attached all the way from
14  IV,  2 |             the anal vent; and this duct is connected with the ovary
15  IV,  2 |             flesh is in betwixt the duct and the gut; for the gut

17  IV,  2 |     observed in quadrupeds. And the duct is identical in both the
18  IV,  2 |          sexes; that is to say, the duct in both is thin and white,
19  IV,  4 |         larger snails, a long white duct enveloped in a membrane,
