from the periphery of the cell-body to form the yet larger 
bundles found in the axone hillock. The dendrites a and 6 
- are subdivided into two branches. In this case the branches 
are also connected by a few fibrils. These branches which 
are divided from the main dendrites (a, 6,) receive fibrils from 
various regions of the cell-body. 
From the above description, two important relations are 
evident: (1) That each dendrite is connected by the fibrillar 
bundles with several and possibly all the others, and (2) in 
each case, the nucleus is partially surrounded or encircled by 
the fibrillar bundles, on their way from the dendrites to enter 
into the neuraxone. 
As arule, the fibrils in the dendrites are very conspicuous, 
presenting long continuous lines, while in the cell-body they 
take tortuous or irregular courses, so that the cross-section 
of the cell-body presents minutely dotted areas, representing 
the cross-section of the bundles. From this, it is inferred 
that the entire course of some of the bundles must be very 
complex. 
Fig. 6 is a diagrain reconstructed from the serial sections 
of the cell-body in order to depict schematically its structure 
and to show the fibrillar tracts distributed throughout it. 
Let us take any one of the dendrites from the Fig. 6, and 
trace the lines which represent the fibrillar bundles. In the 
dendrite (4), black continuous lines present the out-going 
fibrillar bundles, while dotted lines in the same dendrite 
represent the in-coming fibrillar bundles from other dendrites. 
If we trace one of the black lines (3), it enters into the den- 
drites which lie in both sides, and other black lines (1) run 
toward the nucleus and partially encircle it. The fibrils con- 
tinue from the nucleus toward the axone and finally enter 
into the axis cylinder. In the remaining dendrites, the 
fibrillar tracts are just the same in their distribution with 
those of dendrites (0). 
In some cases, the fibrillar bundles which run from the 
dendrite not only enter into the dendrites which lie nearest 
on both sides, but they also connect with other dendrites 
further distant (2). In the cross-section of the cell-body, we 
notice very often the following appearance: ‘The neighbor-
