Memory In the Fish.

Continuing his experiments as to whether fish possess memory of association of ideas, M. Oxner obtains some further results. He already found that by placing a red cylinder containing food and also an empty green cylinder in the aquarium with a single fish, the latter soon learned to enter the red cylinder each time it was immersed and avoided the other one. In his later researches, says the Scientific American, he finds that the fish goes into the red vessel and waits until some crumbs are dropped into it, which he then eats. A more striking point is that at other times the fish enters the baited red vessel, even though he does not appear to desire food, seeing that he does not eat at such times. The factor of hunger was, therefore, eliminated here, and we have to do with a habit or a reflex action.
