1897. HAVE FISH A MEMORY ? 121 



fish really have a memory, that they gain experience and can make 

 use of it, then we should have to give up the usually accepted opinion 

 that memory has its seat in the brain-cortex. Therefore, it is 

 extremely important to have an entirely new collection of observations. 

 Dr. Edinger begs all, who are in any way interested in fish, and 

 especially anglers and naturalists", kindly to send an account of any 

 observations they may have made to him at 20 Gaertnerweg, 

 Frankfurt a. M. He requests them particularly to take nothing as 

 a well known fact. The smallest observation may prove of the 

 greatest importance.
