organs both of plants and of animals. The male or- 

 gans are then taken up as a distinct subject, first in 

 plants and then in animals, both at the times in which 

 they do not breed, and in the breeding season, to 

 shew their different states. To these are added a 

 number of parts which answer secondary purposes 

 in generation, and may be considered as appendages. 

 The female organs are next exhibited in the maiden 

 state, in every class of animals, demonstrating the 

 shape and length of the oviducts, the form of the 

 uterus, the length of its horns, with the varieties in 

 their structures, and the instances in which these 

 horns are entirely wanting, as in some monkeys ; to 

 which are added other peculiarities of structure. 

 They are then exemplified in the impregnated state, 

 beginning with the seeds of vegetables, and those 

 which have both seeds and young shoots, as the 

 onion. The eggs of insects follow next, with their 

 changes, particularly the silk-worm. The spawn of 

 fish are next shewn, first in those which have eggs, 

 and then in those which have their eggs hatched in 

 the oviducts, as the dogfish. 



The arrangement then proceeds to the formation 

 and incubation of the egg in the fowl, and the pro- 

 cess of fetation in the quadruped, with their pecu- 

 liarities, and the different structures and appearances 

 of the placenta. Added to these are the peculiari- 

 ties of the foetus, and the different modes by which 

 the mother gives nourishment to her young. 



Besides the preparations of the parts themselves
