The axons of Dogiel’s Type II cell are figured by that author 
as passing through several ganglia giving off collaterals and 
finally ending by branching in another ganglion. In the text, 
however, he does not claim to have followed such an axon to its 
termination. But, as we have said before, no one has been able 
to confirm Dogiel’s findings in regard to these cells. 
Both Dogiel (95) and Huber (’99) are of the opinion that the 
fine fibers which enter the ganglion through its various branches 
and take part in the formation of the intercellular plexuses are 
the axons of cells in other sympathetic ganglia. Satisfactory 
evidence of this is not presented, however, and in the next 
section of this paper we will present what seems to be conclusive 
evidence that these fine fibers are of cerebrospinal origin. 
While it has not been shown that the axons of sympathetic 
ganglion cells ever end in connection with the cells of the same 
or adjacent ganglia, it seems to be well established that these 
axons may give off collaterals within these ganglia. The axons 
have been seen to give off collaterals either in the same or adja- 
cent ganglia by v. Lenhossék (’94), Dogiel ((95), and Michailow 
(11). These do not seem to be present on the majority of the 
axons. Michailow is the only one who has seen the mode of 
termination of these collaterals. According to him (fig. 8), they 
end in little plates, either in the connective tissue of the ganglion 
between the nerve cells or pressed against the capsule of a cell. 
From their mode of termination it is not evident how these 
collaterals could serve to transmit impulses from one neurone 
to another. They rather resemble certain collaterals on the 
axons of spinal ganglion cells, seen by Huber, Dogiel, and Ranson, 
which since many of them end on the cell from which the axon 
arose cannot serve for the spreading out of nerve impulses. 
Huber (713), in summing up the evidence concerning the inter- 
connections of the cells of the sympathetic ganglia, concludes 
that “there is at hand morphologic evidence that the neuraxes 
of sympathetic neurones, the cell bodies of which are in one 
ganglion, terminate either on the cells of the same ganglion or 
of other ganglia.’’ To us the evidence seems far from convincing. 
Such fragmentary and unsatisfactory histological evidence as
