GENERATION OF ANIMALS, III. xi. 



it in these regions, although there wants to be a kind 

 corresponding to the position of fire '' in the series, 

 since fire is reckoned as the fourth of the corporeal 

 substances. But always, as we see, the shape and 

 appearance which fire has is not its own ; on the 

 contrary, fire is always in some other one of the sub- 

 stances, for the object which is on fire appears either 

 as air or smoke or earth.'' No ; this fourth tribe must 

 be looked for on the moon, since the moon, as it 

 appears, has a share in the fourth degree of remove. 

 However, these matters should form the subject of 

 another treatise. 



With regard to the Testacea,"^ then : some of them (a) Side- 

 take shape spontaneously, others by means of the paction? 

 emission of some special substance from themselves, 

 though these too are often formed from a sponta- 

 neous composition. We must here apprehend the 

 ways in which plants are generated. Some plants 

 are formed from seed, some from sUps planted out, 

 others by sideshoots (e.g., the onion tribe). Now the 

 last-named is the method by which mussels are 

 formed ; small ones are always gro\^ing up by the 



the salamander, which cannot be destroyed by fire ; the 

 History of Animals passage is, however, excised by A.-\A'. 

 There is a long discussion in Jaeger, Aristotle, 144-14.8, in 

 which the doctrine of fire-animals is involved. Jaeger tries 

 to prove that the doctrine that there were animals that were 

 engendered in fire must have come in one of Aristotle's 

 dialogues {On Philosophy), and by a curious blunder states 

 that it does not come in History of Animals {loc. cit., to which 

 he actually refers) ; but in fact Aristotle's words are yivercu 

 drfpLa ev t(x> irvpi. Jaeger makes no reference at all to the 

 present passage.
