Sipnpathetic of Fishes.— This system, as being an off- shoot or subordinate clement of the general myelencephalous series of nerve-organs, is differentiated by progressive steps. In the Myxinoid Fishes it is represented by the intestinal branch continued from the confluence of the two nervi ^'agi. In Osseous Fishes the visceral plexuses are continued into or connected with slender nerves, accompanying the aorta along the hremal canal, and representing the trunks of the sympathetic in higher Verte- brates. The first or anterior communication of this nerve, in the Cod, is with a branch of tlio fifth, and a fllament is sent forward to the ciliary ganglion : in the Carp a filament joins the abducent nerve, to which Cuvicr thouglit he had also traced a filament of tlie sympathetic in the Cod ; the sympathetic next communicates with that anterior portion of the vagus (the glosso-pharyngeal) which joins part tif the acoustic nerve, and supplies the first par- tition of flic gills ; the sympathetic trunks also receive accessions from the trunks of the vagus, and, converging, intercomnumicate.
