TABLE II 



AVERAGES OF AI,L RECORDS FOR FIRST AND SECOND PERIODS 



The table shows that M. has added between one-third and one- 

 half of the average of four records before the rest to the average 

 of the first four records after the rest. The proportion is not so 

 great for B., yet it is high. The averages for all records before 

 the rest compared with the averages for all records during the 

 second period are found in the second part of the table. They 

 show considerable practice gain. The left hand for M. shows a 

 greater actual gain here than in the first part of the table, the 

 figures being 409 for the difference in the average of all records, 

 and 335.7 the difference in the average of the four compared, the 

 later records being lower than the earlier ones. Both reagents 

 suffered greatly from lack of inurement during the first period. 

 (The protocol contains a note to the effect that the general bodily 

 condition was exceedingly unfavorable to the continuation of 

 the experiment.) The right hand of M. and the left hand of B. 

 lost continuously, showing that the condition grew worse rather 

 than better, six days not being sufficient to habituate the hands 

 to the experiment. During the rest complete relief apparently 

 was found for the general bodily condition so that the first rec- 

 ords after the rest show considerable increase. The average 

 daily increase, however, for the second period is either very small 

 or a negative quantity except for the left hand of B. Perfect 

 habituation, therefore, had not been attained. Two records a
