el, 
the central vein of the lobule, and no other nerve filament could be 
found connected with it, or with its branches; alone, it divided and 
formed junctures with its own branches and with no other nerve. The 
evidence from the small number of specimens showing this network is 
of course not conclusive that the hepatic nerves do not anastomose 
with one another; but it is a point for thoughtful consideration whether 
the branches from one nerve do actually conjoin with the extensions 
of another. It is also to be noted that the hepatic nerves in follow- 
ing the biliary canaliculi keep generally as far as possible from the 
course of the intra-lobular portal capillaries, which is doubtless not 
without physiological meaning. 
So many direct endings from the portal and hepatic artery nerves 
are to be found that do not form terminal plexuses between the liver: 
cells, that it is somewhat doubtful if the liver lobules have everywhere 
this plexus. Nerves enter the lobules for long distances, branching 
as they go, finally terminating in end-bulbs without forming a com- 
plete plexus, as may very frequently be seen. At other times their 
course is short, and a single nerve filament from the inter-lobular 
nerves may shortly end within the lobule in an end-bulb without vis- 
ible branching. 
The relation between the nerves and the biliary capillary-plexuses 
are always very much the same and approximately constant. The 
nerves come off from portal, biliary, and hepatic artery systems, and 
after running a short distance usually join an arm of the neighboring 
plexus of gall capillaries, and are then continued for some distance 
upon their sheaths, and perhaps reappear further on, if there is a space 
adjacent where the capillaries are not stained; and then may go on 
to join another capillary, finally disappearing upon it. Nerves may 
also be seen crossing directly between the rows of liver cells, without 
reference to the arrangement of the capillaries as in fig. 10, where a 
single nerve that ran among a number of others (not drawn), after 
developing several short branches that end in coarse knobs; finally 
runs over the rows of cells, almost directly in the centre of the space 
between the capillaries, and eventually is lost upon a gall capillary 
after giving off a single branch in its course. 
Figure 7 represents a coarse plexus of gall capillaries along the 
margin of an inter-lobular space, with several nerves coming from 
above joining the gall canaliculi, and visible at intervals, owing to 
their irregular course upon them. The lower figure in the same 
drawing also shows a nerve fibre joining and running on a capillary, 
the fibre probably being a continuation of one of the upper stems,
