lants raised from seed; they
die annually, and produce others rather more perfect than the
parent for several years, and then produce sexual flowers.
The Aphis is in a similar manner hatched from an egg in the
vernal months, and produces a viviparous offspring without
sexual intercourse for nine or ten successive generations;
and then the progeny is both male and female, which cohabit,
and from these new females are produced eggs, which endure
the winter; the same process probably occurs in many other
insects.]

[Footnote: _Imagination's power_, l. 118. The manner in which
the similarity of the progeny to the parent, and the sex of
it, are produced by the power of imagination, is treated of
in Zoonomia. Sect. 39. 6. 3. It is not to be understood, that
the first living fibres, which are to form an animal, are
produced by imagination, with any similarity of form to the
future animal; but with appetencies or propensities, which
shall produce by accretion of parts the similarity of form
and feature, or of sex, corresponding with the imagination of
the father.]

[Footnote: _His nymphs and swains_, l. 122. The arguments
which have been adduced to show, that mankind and quadrupeds
were formerly in an hermaphrodite state, are first deduced
from the present existence of breasts and nipples in all the
males; which latter swell on titillation like those of the
females, and which are said to contain a milky fluid at their
birth; and it is affirmed, that some men have given milk to
their children in desert countries, where the mother has
perished; as the male pigeon is said to give a kind of milk
from his stomach along with the regurgitated food, to the
young doves, as mentioned in Additional Note IX. on Storge.

Secondly, from the apparent progress of many animals to
greater perfection, as in some insects, as the flies with two
wings, termed Diptera; which have rudiments of two other
wings, called halteres, or poisers; and in many flowers which
have rudiments of new stamina, or filaments without anthers
on them. See Botanic Garden, Vol. II. Curcuma, Note, and the
Note on l. 204 of Canto I. of this work
