INTRODUCTORY NOTE 



The problem of the synapse and the transmission of stimulus 

 from one nerve cell to another has been a topic of study for more 

 than a century; we can, however, say in the retrospect that it 

 was really impossible to come to any safe result on this subject 

 before the discovery of Golgi's method. Although recent stud- 

 ies by many investigators by means of different methods (Apathy, 

 Bethe, Held, Cajal, Bielschowsky) have brought forth many a 

 valuable contribution, we are not yet fully enlightened in many 

 respects. On the basis of their exploration by means of the 

 Golgi method, Golgi and his pupils came to the hypothesis that 

 the gray matter of the central nervous system contains a con- 

 tinuous mesh-work, which consists of the telodendria of the axone 

 and of the initial collaterals of the cells of the first type and of 

 the collaterals from tracts. Forel (9), Cajal (12, 13), KoUiker 

 (9), Retzius (26), and others denied the existence of this net- 

 work on the strength of their observations. They declared that 

 the Golgi net is a false net-work, which in fact is a kind of felt- 

 work made of the dense processes of neighboring nerve cells.
