CONCLUSIONS. 
1. A memory-image of the stimulus either entirely or partially 
inaccurate, exerts on its recognition at a later time an inhibition, 
revealing itself in a complete or partial sensation of novel experience 
for the stimulus. — 
2. In the ease of an inaccurate image of imagination the absence 
of a false recognition reveals itself in the absenee of this inhibition ; 
the figure reproduced inaccurately is recognized at a repeated im- 
pression in a vast majority of cases. 
3. Presumably the absence of a distinct inhibition to the recog- 
nition of the stimuli, which have been altered objectively at their 
second presentation, is to be ascribed to the absence of a false 
recognition in the interval. 
Anatomy. — “The phylogenetic development of the cerebellar nuclei.”

The problem of the cerebellar function, or functions, has of 
late years attracted a great deal of attention. lts solution is being 
looked for in the direction of co-ordination of movement and tonus, 
and both of these again in connection with somatic and labyrinth 
stimuli. As regards the comparative anatomy, comparative morpbo- 
logical research first drew attention to the connection between 
cerebellar development on the one hand, and bodily form and the 
accompanying muscular functions on the other hand, as has been 
demonstrated by Bo.k'), whose researches have been confirmed 
repeatedly by physiologists, recently by ‘Thomas and Durver *). 
Microscopical comparative anatomy also shows most clearly the 
connection between the cerebellum and the statie central organ; 
as has been pointed out, in particular by Eprncer *). 
The result of a comparative anatomical study of the cerebellar 
nuclei, which I conducted in the Institute for Brain Research at 
Amsterdam, also pointed to a connection with the vestibularis. Just 
as the cerebellum has developed in the lower vertebrates at a place
