 1   I,  2 |          uterus, in the male the testes and the penis, in all the
 2   I,  2 | sanguinea; for some of them have testes and others the corresponding
 3   I,  3 |         not all alike as regards testes and uterus. Taking the former
 4   I,  3 |       that some of them have not testes at all, as the classes of
 5   I,  3 |     spermatic ducts. Others have testes indeed, but internally by
 6   I,  3 |      those animals which have no testes at all, these ducts unite
 7   I,  3 |         For all these have their testes internal near the loin,
 8   I,  3 |          the vivipara have their testes in front; some of them inside
 9   I,  3 |       always double, just as the testes are always two in the male.
10   I,  4 |     grasp the final cause of the testes. Now if Nature makes everything
11   I,  4 |         is neither serpents have testes nor have fish; for they
12   I,  4 |          so those which have not testes but only ducts, or which
13   I,  4 |          It is for this that the testes are contrived; for they
14   I,  4 |          about Animals.) For the testes are no part of the ducts
15   I,  4 |         oviparous quadrupeds the testes receive the spermatic secretion,
16   I,  4 |         case of birds, for their testes are much enlarged at the
17   I,  4 |         are very large. When the testes are internal the act of
18   I,  4 |        is not emitted before the testes are drawn up.~
19   I,  5 |       necessarily either have no testes also, or at any rate not
20   I,  5 |         that have both penis and testes have them in the same situation.~
21   I,  5 |          rate that have external testes, the semen is collected
22   I,  5 |          the vivipira have their testes in front, internally or
23   I,  5 |   reasons why those animals have testes which have them, and why
24   I,  6 |      those animals which have no testes are deficient in this part,
25   I,  6 |         matured. So they have no testes, and the ducts are straight
26   I,  6 |          this connected with the testes in the system of quadrupeds,
27   I,  7 |         said above, have neither testes nor penis, the latter because
28   I,  7 |          were further delayed by testes. (This happens also if the
29   I,  7 |     reason why some animals have testes and others not. Serpents
30   I,  12|         always internal, but the testes sometimes internal, sometimes
31   I,  12|     easily injured and cold. The testes vary in position because
32   I,  12|          Therefore, whenever the testes are visible, they have a
33   I,  12|      fish and reptiles, then the testes must needs be internal.
34   I,  12|          these animals for their testes being internal besides those

36   I,  13|        those which have internal testes, the ducts are fixed from
37   I,  13|      fixed in like manner if the testes are external; then they
