EXPLANATION OF THE TABLES. 145
Fig. V. and VI. Shew in what way the nerves from the thoracic gan-
glia are joined with the proper intercostal nerves.
Fig. V. Represents the nerves of their natural size; and Fig. VI. mews
the same nerves as they appear through a magnifying glass.
At N O P the anterior branch, or, as it is commonly called, the trunk of
the proper intercostal nerve, is shewn to consiit of a plexus of nervous
fibres.
Q^Is the outer end of the principal nerve which joins the thoracic ganglion
to the proper intercostal nervei
RS Are branches of Q^ which are connected by plexus to the proper in-
tercostal nerve, nearly as the disserent branches of that nerve are connec-
ted to each other. Some branches, as T, seem, by their direction, to
go from the proper intercostal to the great sympathetic ganglion;
others seem to come from the ganglion of the sympathetic to theproper
intercostal nerve.
