Transverse section taken through the sill showing frontal cells (FC) and lateral cells (LC ) Arrows indicate specific fluorescence in the axoiis of the branchial nerve located under the gill epithelium. A nerve cell ( NC) is si en adjacent to a gill filament; scale = M- cose axons were distributed to the lateral and frontal epithelium of the gill filament. The quantity of fluorescence and number of varicosities was greatest under the frontal epithelium. Xo nerve cell bodies penetrated the gill epithelium but the cells were often observed adjacent to the gill filament (Fig. S). A few nerve cells which did not show anv specific fluorescence contained coarse- granules showing a yellow-orange autofluorescence. Such autofluorescent granules were also located in the branchial nerve but could readily be distinguished from the specific fluorescence. Specimens were subjected to unilateral sectioning of the branchial nerve in the vicinity of the visceral ganglion. The gills on the intact and severed sides were excised at twenty-four hour intervals. In the distal portion of the severed nerve most of the yellow color of the nerve cells and axons had disappeared within seven days after the operation. The fluorescent material observed in nerve cells and axons situated proximal to the lesion (, nearest the visceral ganglion) appeared unchanged, or a considerable accumulation of fluorescence was observed. In a few cases there was increased fluorescence in the nerve cell bodies in the cortex of the visceral ganglion. The degree of fluorescence appeared unchanged in gills in which the branchial nerve was intact. Intramuscular injection of reserpine caused a disappearance of specific fluores- cence in a minimum of three davs after Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - colorat
