den sensiblen Wurzeln der Riickenmarksfasern durch die Ver-

When we consider these words and the influence that at such a 
time was exerted by the well-known experiments of C. Bernard 
and Bidder, we cannot but conclude that Kélliker not only was 
ignorant of the cells from which his large fibers take their origin, 
but also that he had not definitely disproved that they proceed 
from the spinal cord through the dorsal roots and traverse the 
spinal ganglia, as many workers believed. In his textbook 
Ko6lliker (5) assumes the existence of fibers which come off from 
the spinal ganglia, go through the rami communicantes into 
the sympathetic ganglia and continue to the periphery, but he 
does not say anything about the ganglion cells in which these 
fibers have their origin; only in his schema—reproduced, more 
or less modified, in all textbooks—does he picture them as aris- 
ing from spinal ganglion cells of the common type. 
Cajal (6) writes: ‘‘Certains auteurs, et parmi eux Kolliker, 
pensent que des fibres sensitives, nées dans les ganglions rachi- 
diens, pénétrent dans le sympathique avec les rameaux com- 
muniquants blancs et ne font que traverser les ganglions sym- 
pathiques pour se terminer aux surfaces des muqueuses. Nous 
avons vu, nous aussi, dans l’embryon de poulet, des fibres 
épaisses, nées du ganglion rachidien voisin, entrer dans les gan- 
glions du sympathique; mais le fait s’est présenté si rarement 
qu’il nous a été impossible d’étudier l’origine réelle et la termi- 
naison de ces fibres.”’ 
Here reference might be made to the fact that Lenhossék 
(7) has shown that some fibers from the sensory roots enter the 
sympathetic ganglia, also that the sphenopalatine ganglion re- 
ceives a bundle of nerve fibers from the gasserian ganglion, and 
further that some of the peripheral fibers of the geniculate gan- 
glion enter the chorda tympani. Huber (8) believes that these 
sensory fibers do not end in the ganglia, as Lenhossék inclines to 
assume, but pass through the ganglia and become associated with 
the efferent sympathetic nerves. Huber met such medullated 
fibers which are larger than the preganglionic fibers in the frog’s
