that three ideas, wliich could be combined in the same general 

 conception, appealed three times on each list. In the list above tliei-e 

 are three trees, three christian names, and three colonrs. In other 

 lists there are limbs, coins, birds, names of cities etc. A quarter of 

 an hour after the examination with the "Treffer" method, during 

 wliich other tests had been made, the subject was asked which trees, 

 christian names, colours etc. were on the list he had seen. Here 

 again the percentage of correct, incorrect, and mis.sing answers was 

 computed. 



The further investigations were for the purpose of determining 

 the faculty of inculcation, and the annihilation of freshly received 

 impressions by later and stronger ones. 



Inculcation and reproduction of numhers of two //(///?'^.s'. 



A row of five numbei's, which has been carefully selected so 

 that in each test numbers of (be same tens, the combination of the 

 same figin-es, and round (ens, were avoided, was placed before the 

 person to be examined. Af(er he had lead them aloud slowly twice 

 he had to repeat (hem after an interval of one minute. Then the 

 same test was repeated, but now with this difference that additions 

 of two figures had to be done as quickly as possible during the 

 interval. This test was I'epeated duiing five days and the results 

 with the subsequent im|)ediment, and without it, compared. 



liecognition of numbers of tujo figures. 



The test described above was afterwards made in a modified form. 

 The numbers which had been observed and read aloud had now 

 not (o be mentioned, but were to be selected fi'om a list three 

 times as large. 



The percentage of good bad and nil-achievements in both tests 

 was computed. A comparison between the reproduction through 

 association and through recognition, and between the annihilations 

 of subsequent work in these psychical functions was hereby possible. 



Inculcation, Reproduction, and Annihilation of Observations 

 of simple little figures. 



The person to be examined is placed in a dark room before a 

 box in which an opening of 10 cm^ has been made on the foreside. 

 In the box there is an electric lamp, which throws its light on the 

 opening. Small glass plates to which small drawings on white paper,
