B. At the second sitting, the observer was shown, under the 
same laboratory conditions as before, a series of pictures, more or 
less like the previous set as to colour and form. He had only to 
observe them closely and to prevent any interfering association with 
words, objects, or familiar figures. Our object was to apply the 
effect of this impression upon the recognition of the original figures 
as a touchstone by which to test the influence of the reproductions. 
In the following table we illustrate the relative frequency of 
recognition and of sensation of novel experience, either for the 
entire primary figure or for one or more of its fragments. I started 
from 100 experiments with objective alteration of the stimulus in 
the interval; the numbers obtained by the experiment underwent a 
corresponding reduction :

The relatively slight effect of the second impression upon the 
recognition is very 
place in 70°/, of the cases, in spite of an objective alteration of 
the stimulus in the interval. When comparing these data with those 
of Table IL, we will see at once, that the effect of an objective 
alteration of the figure upon its later recognition is very much like 
the influence of an inaccurate image of imagination. In Table II 
obvious: with either subject recognition takes 
the percentages of sensations of novel experience were with M 
respectively 15.8°/, and 10.5 °/,; that of the recognitions 73.7 °/,, 
which values agree fairly well with those of Table VI. If, in this 
connection, we take into account, that the inaccurate image of 
imagination, unlike the memory image, is not recognized as identical 
with a reproduction of a previous observation, we are most likely 
justified in ascribing the absence of a distinct inhibition of the 
second impression at work with the later recognition, to the absence
