Large caudate nerve cell, with smaller cells and nerve fibres, from a thin transverse section of the lower 
part of the grey matter of the medulla oblongata of a young dog. The specimen had been soaked for 
some weeks in acetic acid and glycerine. The lines of dark granules resulting from the action of the acid 
are seen passing through the very substance of the cell in very definite directions. Thus the cell is 
the point where lines from several distant parts intersect (Diagram, Fig.2). It is probable that each 
of these lines is but a portion of a complete circuit (see Diagram in Fig 3). A,A,A, large fibres which 
leave the cell. B, a fibre from another cell, dividing into finer fibres, exhibiting several lines of granules. 
C,C,C, fibres from a younger caudate nerve vesicle. D, fine and flattened dark-bordered fibres E, three 
fine nerve fibres running together in a matrix of connective tissue. F, F,F, capillary vessele.
