✦ Synopsis

WORK OF NERVE CELLS. BY SHINKISHI HATAI. (From f h t Neurolopcal Laborafdry o f the Univrrsity of Chicago.) With Plate 111.

In 1895 HELI) announced that the nerve cells in the central system are densely surrounded by the terminals of the axones which divide into fine branches and form by a local union a complicated network. He also described the clubshaped enlargement of the axone terminals which may be seen in the embryonic nervous system. These terminals, or "Axencylinderendfliche, " are characterized by the presence of the minute granules or neurosomes which stain red by erythrosin.

T h e terminal network or "Pericellular network, " or "GOLGInetz of HETHE" is very well shown by HETHE'S molybdenum technique, as well as by GOLGI'S modified silver technique.

T h e appearances produced b y the foregoing methods are somewhat different from those obtained by the method of HELD. This difference in appearance may be due to the fact that both GOLGI'S and BETHE'S technique cover over the finer and more complicated structures by the precipitation of silver chromate or the molybdenum compound respectively, and thus bring out strongly marked and rather angular meshes of the network. The nature of these networks obtained by HELD, GOLGI and BETHE will be described later on.

I have also noticed and described this pericellular network which not only surrounds the PURKINJE cells and the cells in the corpus trapezoideum, but also the cells in the Ammon's horn and those in the ventral cornua of the spinal cord ( '03).

HELD'S idea that the finer network which surrounds the
