of the whole structure becomes nmch more complicated than that 

 of the primary nerve-fiber of tlie normal HKUusT-corpuscles. However, 

 iiere also the normal relations gradually assert tliemselves. I have 

 not been able to ascertain whether new HERBsT-corpuscles are forming 

 in the course of the regeneration process. 



Round the inner core in Hekbst's corpuscles are disposed a large 

 number of connective-tissue lamellae, separated by lymphspaces. 





Fig. 5. 

 Transverse section of a HERBST-corpuscle, with a nerve-thread that not 

 only branches out in the protoplasm of the cells of the core, but proceeds 

 from there into the connective-tissue lamellae round the inner core, where 

 it continues its growth. 42 days after the cutting of the nerve. 



These lamellae are connected by means of cellular processes, thus 

 forming a whole. 



Now in watching the regeneration it may be repeatedly observed 

 that the nerve-thread, which has passed into the inner core of a 

 HERBST-corpuscle and ramifies in the protoplasm of the core, does 

 not remain enclosed here in its entirety, but that some of the end- 

 branches leave the core and intrude into the tissue of the connective- 

 tissue lamellae. This then is the very place to see quite clearly,
