12 SALMONIA. [FIRST DAY. 



seemed to have had no other effect than that of serving 

 as a sort of sauce piquante, urging them to seize 

 another morsel of the same kind. 



PETS. Pishes are mute, and cannot plead, even in 

 the way that birds and quadrupeds do, their own 

 cause ; yet the instances you quote only prove the 

 intense character of their appetites, which seem not so 

 moderate as Whiston imagined, in his strange philoso- 

 phical romance on the Deluge ; in which he supposes, 

 that in the antediluvian world the heat was much 

 greater than in this, and that all terrestrial and aerial 

 animals had their passions so exalted by this high 

 temperature, that they were lost in sin, and destroyed 

 for their crimes ; but that fish living in a cooler 

 element, were more correct in their lives, and were 

 therefore spared from the destruction of the primitive 

 world. You have proved, by your examples, the 

 intensity of the appetite of hunger in fishes ; Spalanzani 

 has given us another proof of the violence of a different 

 appetite, or instinct, in a cold-blooded animal, that 

 has most of the habits of the genus the frog ; which, 

 in the breeding season, remains attached to the female, 

 though a limb, or even his head, is removed from the 

 body. 



HAL. This is likewise in favour of my argument, 

 that the sensibility of this class of animals to physical 

 pain is comparatively small.
