 5   I,  5 |    quadrupeds have the organ of copulation, since it is possible for

 7   I,  6 |         mature the semen during copulation, as viviparous land-animals
 8   I,  7 |       they seem to be slower in copulation than fish, not only on account
 9   I,  12| necessarily from the details of copulation.) For the same reason they

11   I,  18|        the female in the act of copulation inserts a part of herself
12   I,  18|         movement of the body in copulation, they imply that it is a

22 III,  7 |       just what is required for copulation, as Nature prefers to expend
23 III,  7 |      like a real plant nor from copulation like an animal. Eggs, however,

27 III,  8 |      lay eggs in consequence of copulation and that fish do not; if
28 III,  9 |       of these are generated by copulation, others spontaneously, and

41 III,  10|         should generate without copulation is a thing which may be
42 III,  10|       bees are produced without copulation is the fact that the brood
43 III,  10|        insects are generated by copulation, the parents remain united
44 III,  10|     combs, but they generate by copulation with one another, for their
