 required to convince even a candidate for the feeble-minded 

 institute that a fish can and does distinguish between colors. 



Have Fishes Memory? 



Experts in fish culture and piscatorial experiments are 

 convinced that at least some of the fishes of the sea are en- 

 dowed with memory, as well as other brain faculties that are 

 often surprising. 



Capt. John Patton, former commander of a whaling 

 vessel, upon his return from Alaska, is authority for the in- 

 formation that the most astonishing results have been ob- 

 tained, especially as regards the gray perch, which lives 

 principally on small silvery hued sardine. 



He took some of these and colored them red, and they 

 were then placed in the tank where the perch was, with sev- 

 eral silvery sardines. 



Of course, the normal sardines were at once seized and 

 devoured, but it was not until hungry that the perch made a 

 tentative meal of one of the red colored victims. On recog- 

 nizing the sardine flavor, how r ever, he promptly demolished 

 the remainder. 



Later the perch devoured the sardines irrespective of 

 color, thus showing not only traces of a memory, but also 

 the power to differentiate color. 



Subsequently sardines colored red and blue were placed 

 in the tank together with the silver ones. The same scene 

 was repeated, the blue sardines not being attacked until the 

 others were eaten and hunger compelled investigation of 

 the newcomers. 



Where Birds Are Actually Used as Lamps: 



The price of coal-oil is not an item of interest to the 

 inhabitants of the Island of St. Kilda, which is a favorite 

 haunt of that animated oil-can, the fulmar. So rich is this 

 sea bird in oil that the natives simply pass a wick through
