Not illustrated. 1907 Excerpt: ...not continue the process so long as before, climbing back after two or three minutes and resuming its peregrinations. After again completing the circuit of the vessel, it again reached the side next the window, again thrust certain rays out of the water and felt about for a little, but quickly ceased and went back into the water. It explored the vessel for a few minutes more, then finally came to rest in the angle between the side and the bottom. Its exploration had lasted three-quarters of an hour. Though now no longer creeping about, it was clear that the animal was not at rest, for the tube feet still kept actively moving in one direction after another, for a time. They sometimes stopped for a few minutes, then resumed their activity. It was more than an hour after the starfish had been introduced into the jar before it came to rest. Meanwhile, the other starfish, which had been for a long time in the jar, had seemingly become quite reconciled to it; it did not move about save when roused by special stimulation. The behavior described above is typical; I have observed i% in many cases. It takes place in the same way whether the jar to which the starfish is removed has fresh sea water running through it or not. The varied changes in behavior are clearly not due to corresponding changes in the external conditions. They are of course determined in some way, as are the varied activities of man and other organisms. Changes in the internal condition of the organism set in operation changes in the external activity. It is clear then that the starfish does not always react in the same way to the same external stimulus. It reacts, as does a higher animal, not exclusively to one particular present agent, but to the situation as a whole, including past external fac...
