Against this view that the cerebro-spinal fluid may be regarded in part as a transudate is the fact that it differs from hnn]) Fig. 5 Mitochoiulria in tlit' epithelial cells.

Cerebro-spinal fluid is almost free from protein, while the other fluids contain much more. That the choroid plexus is responsible for the fonnation of cerebro-spinal fluid was suggested by Faivre a long time ago. Luschka, a little later, agreed \\\i\\ him, and practically all ob- servers since, including Pettit and Girard, Studnicka, Galeotti ('97), Garazzani, Meek, Mott ('10), Goldmann ('13) and Gush- ing, regard this structure as fundamental in the secretion of cerebro-spinal fluid. Gushing saw drops of the fluid exuding from this tissue. Goldman noted the extrusion of glycogen in the form of globules from the cells. Weed, in connection \\\ih others, suggests a dual origin of cerebro-spinal fluid—from the choroid plexus and from the perivascular systems of the nervous Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bardeen, Charles Ru
