THE AQUAKIUM, JANUARY, 1897. 



that they take fright, and not from 

 any auscultatory sensation. I remember 

 as a boy, watching a shoal of roach and 

 dace in a fish-pond in England, when 

 suddenly a vivid flash of lightning 

 occurred. It had no visible effect on 

 the fish, but as soon as the thunder 

 came, which fairly made the earth 

 vibrate, they one and all suddenly dived 

 out of sight, not from hearing it, but 

 from the vibration, for T had fired a 



gun just previously at some water- 

 fowl, without its having any effect on 

 the fish. Perhaps some of our fish an- 

 atomists may be able to contribute their 

 ideas on the point, and to account for 

 the peculiar white stony substance that 

 exists in the head of the haddock, 

 which has been attributed to the ear of 

 those fish.
