The person to be examined was now instrncted to mark the 

 groups of four dots witli a vertical and those of tliree dots with a 

 horizontal line, in pencil, in as short a time as possible. The end 

 of every minute was notified by the investigator and had to be 

 recorded by a line. At the end of three minutes there was an 

 interval of two min. and then the work was started again for three 

 minutes, but then with this ditference that now the marking was 

 reversed, the groups of four being indicated by a horizontal, and 

 those of three by a vertical line. This was repeated on live 

 consecutive days, however so that on the even days the reversed 

 marking had to be done in the third minute before the interval. 

 The standard of atteutiveuess could be determined from the results 

 of this work in different ways: 



1. By the number of dot groups that had been examined by 

 the subject. 



2. By the number of mistakes. 



After the grade of attentiveness had been determined in this way 

 1 have investigated whether the phenomena of confusion were to 

 be found in the persons when the grade of consciousness sank. 



The memory was examined by the following method: 



The so-called "Treffer" Method of Müi.i.ku and Pilzecker. 



This consisted herein that during five days eight pairs of words, 



which were typed on a piece of paper and between whom an 



associative connection had been avoided as much as possible, were 



laid before the subject on each day. One of the lists follows here; 



Poplar Air 



Clock John 



Grey Willow 



Jacob Sleep 



Match Chestnut tree 



Violet (Uiarles 



Letter Garret 



Earth Brown 



These words are slowly read aloud in pairs and are then with- 

 drawn from the subject's observation. The first word of each pair 

 was then mentioned by the examiner whereupon the sid)ject had lo 

 name the corresponding word. By computing the number of 

 correct, incorrect, and missing answers one could form an idea of 

 the memory. 



2. The above named pairs of words were chosen in such a way
