S6 Additional Notes. 



Linneus has thence well called hermaphrodite flowers; and that this 

 hermaphrodite mode of reproduction still exists in many insects, as 

 in snails and worms; and, finally, because all the male quadrupeds, as 

 well as men, possess at this day some remains of the female apparatus, 

 as the breasts with nipples, which still at their nativity are said to 

 be replete with a kind of milk, and the nipples swell on titillation. 



Afterwards the sexes seem to have been formed in vegetables as in 

 flowers, in addition to the power of solitary reproduction by buds. 

 So in animals the aphis is propagated both by solitary reproduction as 

 in spring, or by sexual generation as in autumn; then the vegetable 

 sexes began to exist in separate plants, as in the classes monoecia and 

 dicecia, or both of them in the same plant also, as in the class poly- 

 gamia; but the larger and more perfect animals are now propagated 

 by sexual reproduction only, which seems to have been the chef- 

 d'oeuvre, or capital work of nature ; as appears by the Avonderful trans- 

 formations of leaf-eating caterpillars into honey-eating moths and 

 butterflies, apparently for the sole purpose of the formation of sexual 

 organs, as in the silk-worm, which takes no food after its transforma- 

 tion, but propagates its species and dies. 



III. Recapitulation. 



The microscopic productions of spontaneous vitality, and the next 

 most inferior kinds of vegetables and animals, propagate by solitary 

 generation only; as the buds and bulbs raised immediately from seeds, 

 the lycoperdon tuber, with probably many other fungi, and the poly- 

 pus, volvox, and taenia. Those of the next order propagate both by 

 solitary and sexual reproduction, as those buds and bulbs which pro- 

 duce flowers as well as other buds or bulbs; and the aphis, and probably 

 many other insects. Whence it appears, that many of those vege- 

 tables and animals, which are produced by solitary generation, gra- 

 dually become more perfect, and at length produce a sexual progeny. 



A third order of organic nature consists of hermaphrodite vege- 

 tables and animals, as in those flowers which have anthers and stigmas 

 in the same corol; and in many insects, as leeches, snails, and worms;
