the manner in which frogs copulate & fish show how simply instinctive the feeling of other sex being present is — it also shows that semen must actually reach the ovum. — (Why in making a bud, which is to pass through all transformations should there need two organs; whilst in common bud there is no such need. — one would suppose that the vital portion ?nerves? passed through transformation & was received into bud matured by female: such view no way explains Lord Moreton's case: without the nervous matter consists of infinite numbers of globules: generally sufficient for one birth or other)
II. It should be observed that the constant necessity for change in process of generation applies only [to] the more complicated animals.

Is a flower bud produced by union of two common buds??? Amongst buds each one exactly like its parents, all alike in one parent or tree, but not in other trees. — Why should there be a necessity that there should be something each time added to that kind of generation, which typifies the whole course of change from simplest form. — (Because by the process it separates those differences which are in harmony with all its previous changes, which mutilations are not). but why should it demand some further change? Man properly is hermaphrodite (hence monstrosities tend that way from frequency of this tendency all mammals must long have so existed with double union.[)] — At present I can only say the whole object being to acquire differences, indifferently of what kind, either progressive improvement or deter[ioration] .. that object failing, generation fails. — How completely circumstances alone make changes or species!! The view of each man or mammalia being abortive hermaphrodite simplifies case much; & originally each hermaphrodite being simple (are not coniferous trees generally dioecious oldest forms)
