eim nervoeses Netz abgeben, dass nach Golgi Nervenfasern urd 
Nervenzellen verbindet. In dieses Nets treten auszer den eben 
genannten feiner Auslaeiifern, noch ein (i) feine veraestelte Auslaeu- 
fer der motorischen Nervenfaeserri, Welche von den Axencylinder- 
fortsaetzen der motorischen Zellen entspringen, (2) Fortsaetze der

bezeichnet, arber in ein feines Netz sich aufloesen laeszt, (3) endlich 
veraestelte feine Auslaeufer der centripetal wirkenden (sensiblen) 
dunkel-randigen Fasern. Mir will es nun, trotz aller Anerkennung 
der wichtigen errungenschaften Golgi’s, vorkommen, als ob dieexistenz 
eines solchen verwikelten nervoesen Netzes nicht hinreichend sicher 
begruendet sei.” 
The question as to the anastamoses between different gpt-glion 
cells has been laboriously argued. Some few, like Claus, Vv. Hanes, 
Wagner and, more recently, Nansen have denied the existence of such 
connections. Nansen says: 
I have on several occasions firmly denied a common existence 
of direct combinations between cells, not having found any case of 
indubitable anastomosis between cell processes.” ‘^The ‘neuroglia 
cells ’ and fibres, which are interposed between the ganglion cells, have 
certainly assisted a great many writers to see anastomoses, as they have 
not understood the real nature of this supporting tissue.” 
The author admits what we have very frequently seen beyond 
doubt, that lateral communication certainly exists as a result of cell 
division, but seems to believe that there is a subsequent solution of 
continuity. He says :* 
“ When one has examined so many preparations (stained by the 
most perfect methods) as I have, without finding one anastomosis cf 
indubitable nature, I think one must be entitled to say, that direct 
anastomosis between the processes of the ganglion cells does not exist, 
as a rule. What previous writers have supposed to be anastomoses 
is, in my opinion, probably the neuroglia reticulation generally extend- 
ing between ganglion cells. * * * Another objection against a 
direct combination, and which does not seem to have been thought of 
by a great many authors, is the existence of unipolar cells.”
