 1   I,  1 |    animal which possess the two sexes. This is not the case with
 2   I,  1 |     some bloodless animals have sexes so that they generate offspring
 3   I,  1 |         not from a union of the sexes, but from decaying earth
 4   I,  1 |        we find in these the two sexes, not only in the sanguinea
 5   I,  2 |        is secreted from the two sexes, the secretion taking place
 6   I,  2 |     this division into opposite sexes. But if in the sanguinea
 7   I,  19|         by the male and the two sexes reach their goal together,
 8   I,  20|        at the same time in both sexes; and as the neighboring
 9   I,  20|       But in whatever kinds the sexes are distinguished, in these
10   I,  20|    these powers separate in two sexes the body and nature of the
11   I,  23|       which can move about, the sexes are separated, one individual
12   I,  23|    those animals which have the sexes separate. For when there
13   I,  23|        for them to generate the sexes are no longer separated
14   I,  23| together in plants, so that the sexes are not divided in them.
15   I,  23|          As plants they have no sexes, and one does not generate
16  II,  1 |      and point out (1) that the sexes arise from Necessity and
17  II,  1 |        of sense-perception. The sexes are divided in nearly all
18  II,  1 |        the existence of the two sexes. Some animals bring to perfection
19  II,  3 |         in it the parts of both sexes potentially, but has not
20  II,  5 |       corpse. If then, when the sexes are separated, it is the
21  II,  5 |        waters. But whenever the sexes are separate the female
22  II,  7 |        to produce young of both sexes, but mules alone are sterile,
23  II,  7 | secretions. Often, too, in both sexes this state is caused by
24  II,  8 |         horse is soft. But both sexes of the horse cross with
25  II,  8 |       the horse cross with both sexes of the ass, and the offspring
26  II,  8 |      mules are produced of both sexes and are not different in
27  II,  8 |     those of the horse, in both sexes, are hotter. Now when either
28 III,  5 | oviparous. Where, however, both sexes exist and the eggs are produced
29 III,  5 |         they do not dispute the sexes in these. And yet there
30 III,  7 |     fishes this is seen in both sexes. The reason is that the
31 III,  7 |     observed. But as it is both sexes exist in all birds, so that,
32 III,  10|        kinds of animals the two sexes differ. Besides they would
33 III,  10|      have often happened if the sexes had existed in them. It
34 III,  10|   containing in themselves both sexes as plants do. Hence also
35  IV,  1 |       and since we say that the sexes are first principles of
36  IV,  1 |        only in some of them the sexes are separated and in others
37  IV,  1 |      first of the origin of the sexes in the latter. For while
38  IV,  1 |      with each other in the two sexes is only a concomitant result;
39  IV,  1 |        though they see that the sexes differ actually by the whole
40  IV,  1 |   female, or that the different sexes come from the right and
41  IV,  1 |      higher degree, and the two sexes correspond in this manner (
42  IV,  1 |         kinds which possess the sexes must be formed that which
43  IV,  2 |         happens to many of both sexes that they do not generate
44  IV,  3 |         of animals divided into sexes must be preserved, and as
45  IV,  8 |       the voice changes in both sexes when they begin to bear
46  IV,  8 |   secretion is greatest in both sexes in proportion to their size
47   V,  7 |     also in the male and female sexes; in the other kinds of animals
48   V,  7 |      older, nor yet are the two sexes thus opposed, and again
