THE POPULAR SCIENCE MONTHLY. 



gives some details of the results of the experiments in which sim- 

 ple objects were used, extending over a period of four months 

 (fifth to ninth in her life). The number of experiments at each 

 sitting varied from ten to forty ; the position of the child being 

 reversed after half of each series. 



TABI.K I. 



It is evident from Table I that no trace of preference for either 

 hand is discernible during this period ; indeed, the neutrality is as 

 complete as if it had been arranged beforehand, or had followed 

 the throwing of dice. 



I then conceived the idea that possibly a severer distance test 

 might affect the result and show a marked preferential response 

 by one hand over the other. I accordingly continued to use a 

 neutral stimulus, but placed it from twelve to fifteen inches away 

 from the child. This resulted in very hard straining on her part, 

 with all the signs of physical effort (explosive breathing, sounds 

 resulting from the setting of the larynx, rush of blood to the head, 

 seen in flushing of the face, etc.). Table II gives the results ; the 

 number in each series was very small i. e., one to twelve (in one 

 instance only) :

The same cases, distributed according to distance, give us

TABLE III. 



A comparison of II and III with I shows a remarkable differ- 

 ence i. e., during the month ending June 15th, the child showed
