which the hypertrophy of the lateral lobes of the valvula cere- 
belli is due to the special development of secondary connections 
of the lateralis nerves, the primary centers of which also show 
so intimate a relation with the cerebellum. 
It is a great pleasure to me to refer here also to the paper 
published by Stendell,“4 which appeared after I had completed 
the results of my researches, and which agrees in most respects 
with my own results. Stendell’s work is a valuable addition 
to our knowledge of Mormyrus. 
POSTSCRIPT 
After this paper had already been sent to the printers another 
contribution by Stendell appeared in the Verhandlungen der 
Deutschen zoologischen Gesellschaft auf den 24. Jahres-versamm- 
lung zu Freiburg in Br., 1914, entitled, Morphologische Studien 
an Mormyriden. 
In this article he states that, looking for an explanation for 
the excessive developement of the nervi laterales in Mormyrus, 
he found peculiar gland-like organs in the lips of this animal, 
innervated by the nervus lateralis anterior. Stendell was in- 
clined to admit a correlation between the considerable develop- 
ment of the Mormyro-cerebellum and these organs, concerning 
the function of which he was not able to pronounce an opinion 
but which—on account of their innervation—he regarded as be- 
longing to the group of acoustico-lateral organs. Since he says 
he has found a branch of the anterior lateral nerve innervating 
taste buds of the tongue, it is a great pity that he does not say 
whether these fibers, which peripherally run with the nervus 
lateralis anterior, do or do not separate from the other fibers of 
this nerve after their entrance into the central nervous system. 
The cruel war which demands so many victims in Europe has 
also killed this young neurologist, whose work on Mormyrus led 
us to expect a great deal from him in the future. Science knows 
of no nationalism, and we all regret his sudden death.
