No. 3, recognized the bottle at a distance of two feet and went to 

 it. He was given milk, and went to the bottle again. This bot- 

 tle was small and round and was almost completely covered by 

 the hand of the experimenter when he was feeding a raccoon. 

 Were it the whole situation the animal was reacting to, why should 

 he not have come to me, the source of all his food, instead ot mak- 

 ing for the bottle as soon as he saw it. The act in No. 3's case 

 was far too definite to be an accident. I think that he recognized 

 the red rubber nipple. All of the animals now go directly to the 

 bottle if it is set down at all, so it must be hidden. I varied the 

 experiment by lowering the bottle into the room through a win- 

 dow when the raccoons were lying at rest in a remote corner. 

 Within a minute all were clinging to the bottle and struggling to 

 get at the nipple. Next I lowered a small piece of wood, the size 

 of the nipple and wrapped with red cloth to appear like the 

 nipple. AH came to it. Two tried to suck it. At first they 

 seemed unable to distinguish it from the nipple. Perhaps this 

 indicates that they do not rely greatly on the sense of smell. When 

 tried thus again thev merely played w^ith the piece of wood. 



When working with Box 12 (six fastenings), No. 4 refused to go 

 into the box. She was switched twice to make her do so. After 

 this, showing her the whip would make her go in. 



A case of direct searching for the bottle may now be mentioned. 

 On being released from the large cage in which they were confined 

 during experiments. No. 4 went directly toward the corner of the 

 room where she had some days before found the bottle. The 

 total distance was ten feet, but she could not have seen the bottle 

 until she came around a box within two feet of it. All the other 

 raccoors were seen to do this. 



No. 3 was reluctant to go into a complicated box and he formed 

 the habit of biting when I attempted to lift him into it. I held 

 him and thrust a finger down his throat, then whipped him. For 

 five days afterward he would growl, snap at and retreat from me 

 though still on good terms with my assistant, Mr. Erwin. 



Forgetting. — After three days without practice in Box 2, No. 4 

 seemed almost to have forgotten how to work it. There was no 

 directness in her movements and her time records were poor. A 

 period no longer than three days should show" no influence of this 

 sort on a wtU established reflex, and all records agree, I believe, 

 in indicating that a period of some weeks or months would not
