body communicating directly with the intracelkilar neurofibrils. 

 Figure 10 demonstrates clearly that the neurofibrils from the 

 terminal feet enter the cell body. In this figure it is also shown 

 that the intra- and extra-cellular neurofibrils communicate with 

 each other; one might raise the objection against me, that the 

 fibers which enter the cell-body might be the 'cap dendrites' of 

 Bartelmez (4) . On this point I can give the following arguments : 

 first, some of the fibers could be traced back to the part, where 

 they are to be enveloped in myelin sheaths, and, second, it is 

 connected with the cell by means of the terminal foot (fig. 10). 

 Terminal ramification of nerve fibers occurs very often within the 

 'axone cap;' between the ends of individual nerve fibers neither 

 anastomosis formation nor even a simple net formation of nerve 

 fibers came to my observation in the 'axone cap' oron the cell 

 surface. Through careful examination I could always isolate the 

 sharply and intensely dark stained nerve fibers from each other. 



In the previous chapter I already stated that through the simul- 

 taneous impregnation of the Golgi net substance a false picture 

 of a nervous net-work becomes observable in the synapse. Ao- 

 cording to my experience, the, Golgi net substance is to a certain 

 extent antagonistic in its staining reaction to the nerve elements 

 in the Bielschowsky method; when the nervous elements are 

 brought out sharply and dark enough the Golgi net substance 

 remains unstained or is stained quite feebly, whereas the latter 

 is impregnated more or less intensely when the former is stained 

 more feebly. I also stated above that by means of the eosin 

 counterstain the Golgi net substance is demonstrable in red color 

 and is connected directly with the glia reticulum and glia nucleus 

 on the one hand and the nervous elements on the other hand. 

 Figure 15 shows that the nervous elements are covered with a 

 more or less thick layer of the red-stained substance; also the 

 terminal feet are surrounded by the same substance. This pic- 

 ture corresponds to that of the Levaditi preparation, which was 

 described in the previous chapter. 



After this description of my results in both the Cajal and 

 Bielschowsky preparations I go over the discussion of the ques-
