different elementary physiological states, of which each 
is effective at one definite point of the organism, and all 
combined constitute the general physiological state, 
possesses the faculty of depositing independently a “‘spe- 
cific accumulation,” from all indications similar to that 
deposited in the brain by each of the nervous currents 
which make up the different sensations and leave behind 
a mnemonic residue capable of being reactivated or 
revived, By “specific accumulations” of the various ner- 
vous currents we mean here only that every accumula- 
tion is capable of giving as discharge only that par- 
ticular specificity of the nervous current by which this 
accumulation has itself been deposited. 
The extension of this faculty of “specific accumula- 
tion” to all physiological phenomena in general accords 
with the hypothesis that nervous energy is the basis 
for all the phenomena of life. If in the psycho- 
mnemonic phenomena properly so called the action 
of nervous energy produced by “discharge” or 
by stimulation of the respective center appears in the 
foreground, whereas the specific physico-chemical 
phenomena accompanying the discharge remain in the 
background so that until recently they were quite over- 
looked, that would be—according to the fundamental 
concept of Claude Bernard on the essential identity of 
all the different forms of irritability of living matter— 
a difference of degree only but not of essence, inasmuch 
as true physiological phenomena accompanying the re- 
spective stimulation (muscular contraction, glandular 
secretion, etc.) appear with greater distinctness, where- 
as the specific nervous phenomena which likewise accom- 
pany this physiological activity are less perceptible. In 
this way we have tried to explain the fundamental mne-
