FINER STRUCTURE OF SYNAPSE 145 



raise objection against me that the nerve fibers, which I have 

 demonstrated in the beams of the Golgi net, might be neurogUa 

 fibers. Concerning this I should raise the following points: in 

 the first place, I could not, like Bartelmez (4), find any neuroglia 

 fiber by means of specific neuroglia methods, and in the second 

 place, I was able to follow the nerve fibers far back to the part 

 where they have myelin sheaths. 



As quoted above, the connection of nerve fibers with the Golgi 

 net was stated by Golgi; also Held himself figured such points 

 from his Golgi preparations (fig. 8, table 13, 1902). But he 

 immediately denied the demonstrative power of these findings 

 on account of the drawback of the Golgi technic mentioned above. 

 I wonder why Held was so severe in his criticism concerning 

 Golgi's method, when the picture was unfavorable to his opinion, 

 whereas he avails himself of it to its full extent, if it is convenient 

 for him. Held (17) formerly demonstrated (figs. 5 to 8, 1897) 

 his 'pericellular nervous terminal net' around a certain kind of 

 nerve cell. Later, however, he altered his interpretation of these 

 figures so that only his figures 7 and 8 can hold their ground even 

 in his extended critical consideration. If one, however, com- 

 pares Held's figures 5 and 6 with 7 and 8, one can hardly see why 

 in the figure 6 and in the light part of the figure 5, which showed 

 the impregnation of the Golgi net, he should later have seen 

 evidence of a nervous net-work. To me all these figures, espe- 

 ' cially 6 and 7, look very much alike ; in the light part of the figure 

 5 the nodal points of the net-work are not thickened, but to my 

 mind one should not be surprised at this in a method which is 

 so inconstant in its results. Besides, it must be emphasized here 

 that Held (17) did not rely on satisfactory evidence, when he set 

 up his 'pericellular nervous terminal net.' He considered the 

 pericellular net-work as the nervous-one merely for the reason 

 that he found the connection between the net-work and the ar- 

 borization of the nerve fibers and the thickening of the nodal 

 points of the former. The relation between the Golgi net and 

 the nerve fiber arborizations has been settled, I believe, through 

 my present investigation. Moreover, despite the characteriza-
