investigation; but on the basis of my findings I should be able 

 to declare, I believe, that they accompany the neurites to their 

 ends, connecting each other by means of delicate beams and 

 thus forming the Golgi net in the axone cap as well as on the 

 cell surface. Also the minute cap dendrites described by Bartel- 

 mez (4) are enclosed in the yellow net beams of the Golgi net. 



Bielschowsky (18) also demonstrated the Golgi net by his 

 method and he could even observe in harmony with Bethe (7) 

 that nerve fibers stream on many points into the beams of the 

 Golgi net. Further, he and Wolff (11) expressed themselves about 

 the relation between Bethe's net-work and the 'terminal nervous 

 net,' which they demonstrated as follows: 



The mesh-formation in our picture is not as regular as that which 

 Bethe's technic yields. Also the net beams appear in ours more deli- 

 cate than those in Bethe's. Still we consider it is probable that both 

 methods demonstrate in this the identical structure. The difference 

 might depend upon the fact that in Bethe's technic the plasmatic 

 component of the net-work and in ours, the fibrillous component, be- 

 comes more manifest in the preparations. As Bethe (7) insisted, the 

 beams of the net-work are not homogeneous but delicate fibrils are 

 recognizable in them, which are continuous with the intracellular 

 neurofibrils. 



Now, if one compares this statement with my description, it 

 becomes highly probable that the so-called 'plasmatic compo- 

 nent' of the net-work of Bielschowsky and Wolff is to be inter- 

 preted as the Golgi net substance. As will be described in the fol- 

 lowing chapter, in some of my Bielschowsky preparations the 

 sharp and intensely impregnated endings of neurites in the synapse 

 of Mauthner's cell were seen connected with each other by pale 

 stained beams forming a net-work. In the eosin counterstain 

 of this preparation the sharp and dark stained components of 

 the net-work were covered by more or less thick red sheaths and 

 they were interconnected by red-tinged bridges so as to form a 

 net-work (fig. 15). It was extremely interesting to find that 

 the red-stained component of the net-work was directly contin- 

 uous with the glia reticulum and with the glia nucleus. Thi.« 

 picture is to some extent equaled by my findings in the Levaditi
