signal, to which she always reacted. It will be observed 
that 50 trials put the cat in the same position that 350 had 
done in her first experience, although in that first experience 
she had had only about a hundred trials after the association 
had been perfected. The association between the first 
signal and climbing up was perfect after the eighty days.

‘All these data show that/fraces of the connections once, 
formed are very slow in being lost.) If we allow that part 
of the time in the first trial in all these cases is due to the 
time taken to realize the situation (time not needed in the 
trials when the association is forming and the animal is 
constantly being dropped into boxes), we may say that the 
association is as firm as ever for a considerable time after 
practice at it is stopped. How long a time would be re- 
quired to annul the influence of any given quantity of 
experience, say of an association which had been gone 
through with ten times, Icannot say. It could, if profitable,
