GENERATION OF ANIMALS, III. x.-xi. 



to theories, — and to theories too pro\ided that the re- 

 sults which they show agree Avith what is observed." 



[Another piece of evidence which goes to show 

 that bees are generated A\ithout copulation is that 

 the brood appears to be quite small in the cells of the 

 comb, whereas those insects which are generated by 

 means of copulation (a) spend a long time in inter- 

 course, and (6) quickly bring forth their offspring, 

 which is of the nature of a larva and of considerable 

 size.] *• 



With regard to the generation of the animals that Hornete 

 are akin to bees, such as hornets and wasps/ the "^^^v^ 

 situation is in a way similar in all of them, but the 

 extraordinary features are lacking, and this is what 

 we should expect, because they contain no diWne 

 ingredient as the tribe of bees does. Although the 

 " mother-wasps " as they are called do indeed gener- 

 ate, and mould the first of the cells, it is by copulation 

 with one another that they generate, as their copula- 

 tion has often been observed. To find out the various 

 differences between each of these kinds of creatures, 

 and between them and bees, the records given in the 

 Researches ^ should be studied. 



We have now described the generation of all the 

 Insects, and we have next to describe the Testacea. 



The circumstances of the generation of these XI 

 animals also is to some extent similar, to some extent j" cti^ of^ 

 dissimilar, to those of the others. And this is what Tesuc«u 

 we should expect, for compared with animals, they 

 resemble plants, compared with plants, they re- 

 semble animals, so that in a way it seems that they 

 are generated from semen, but in another way not ;
