by the Golgi method, and do not lend support either to the view of 
pericellular networks of neurofibrillae, nor of intracellular neurofi- 
brillar structures. 
In stating these conclusions I do not wish to be understood as holding 
that sense cells are morphologically or physiologically independent of 
axis cylinders. It is now recognized that even in those structures in 
which there seems to be the greatest distinctness of cell limits, the cells 
are far less independent of each other than was believed in the earlier 
days of the cell theory. So far as it is safe to judge from the conditions 
found in the ear, however, I believe that we may say that the cell 
theory is as applicable to nervous tissue as it is to other tissues of the 
animal body, and that the neurones, which are to be thought of as the 
peculiar and complex cells of which nervous tissue is composed, are as 
independent of one another, and as independent of other kinds of cells, 
as are the cells which compose many other animal tissues.
