 1   I,  4 |         the spermatic organs in males, if we are to investigate
 2   I,  13|        vivipara. Wherefore both males and females in this class

 4   I,  14|     belly against the back. The males have fine spermatic ducts,
 5   I,  16|       larger than the male. The males do not appear to have spermatic
 6   I,  17|         considered, whether all males do so, or not all; and if
 7   I,  18|        this from below into the males above, not in all cases,
 8   I,  18|      seems clear that, when the males do emit semen, then also
 9   I,  19|         females to the semen in males. The circumstances connected
10   I,  19|       semen begins to appear in males and to be emitted at the
11   I,  19|      smaller in females than in males among the vivipara, since
12   I,  20|    spiritus; this is clearer in males in the testes, but appears
13   I,  21|       for this reason that some males which unite with the female

15   I,  22|       is the way in which these males contribute to generation.
16   I,  22|      reason of weakness in such males Nature is not able to do
17  II,  4 |         secretion, have not all males one to correspond? For some
18  II,  4 |        reason why it is not all males that have a generative secretion,
19  II,  4 | considerable width, whereas the males that emit semen have only
20 III,  1 |      and so on, wherefore their males tread often and their females
21 III,  1 |      for generation without the males. As for embryos being formed
22 III,  1 |        less degree) without the males, the fact has been observed
23 III,  5 |         what are supposed to be males only in the same way as
24 III,  5 |         is no difference in the males of cartilaginous fishes
25 III,  5 |    semen can be squeezed out of males of both classes at the right
26 III,  5 |     when they say this. For the males have their milt and the
27 III,  5 |       but gradually, nor do the males emit all the milt at once.
28 III,  5 |         is that the milt of the males is used up. Therefore it
29 III,  5 |         of the females, for the males always attend them, shedding
30 III,  6 |       have such a mark, but the males are taken more frequently;
31 III,  7 |  discharging their eggs nor the males their milt, whereas in the
32 III,  7 |   uterus near hypozoma. For the males and females of the one class
33 III,  7 |         of fish differ from the males and females of the other

36 III,  7 | possessed by females as well as males, and indeed by all living
37 III,  8 |        larger than those of the males, to protect the eggs; the
38 III,  8 |       away from themselves. The males of the cephalopoda sprinkle
39 III,  10|       the drones female, for no males are in the habit of working
40  IV,  1 |    means of heat. Therefore the males of animals must needs be
41  IV,  1 |    animals with blood, i.e. the males, is moderate in quantity,
42  IV,  1 |      parts of this secretion in males are only passages. But the

45  IV,  2 | difference in the production of males and females if copulation
