THE HABITS AND HAUNTS OF FISH. 



POWER OF VISION, HEARING, ETC., POSSESSED BY 

 FISH. PERIODIC MOVEMENTS AND HABITS OF 

 SALMON, BROWN TROUT, CHARR, GRAYLING, 

 AND PIKE. 



THE habits of fish depend in no small degree 

 on the power of their senses, and to these 

 we will briefly allude before dealing with the
