Class VI. ASCARIS. 6\ 



Common in the intestines of the herring and 

 other sea-fish. Aristotle* remarks that the 

 Ballerus and Tillo are infested in the dog-days 

 with a worm that torments them so much, 

 that they rise to the top of the water, where the 

 heat destroys them. Bleaks are observed to 

 rise at certain seasons to the surface, and tum- 

 ble about for a considerable space, in seeming 

 agonies. I suspect them to be affected in the 

 same manner with those Aristotelian fish. Tab.
