    EXPERIMENTS ON THE SECTION OF THE SPLANCHNIC AND MESENTERIC NERVES. After the issue of our last report, an additional series sections of Mesenteric of experiments regarding the effects Nerves, of nerve-sections was carried on, with the view of finally satisfying ourselves whether any destruction of epithelium or denudation of the mucous membrane were necessary for the occurrence of a copious effusion of fluid into the intestinal tube, and also whether the observations which we had previously made regarding the coincidence of such effusion with partial but not with total deprivation of nervous supply, would stand the test of repeated experiments. The following table shows the result of twenty-one experiments on section of the mesenteric nerves :— TABLE XX. Table XX.—Sections of Mesenteric Nerves. No. Nature of oeration. Eesult. 1 2 3 4 Complete section of nerves of a loop of intestine. Section of mesenteric nerves Section of mesenteric nerves Section of mesenteric nerves Exudation of watery fluid. Loop half- full of fluid, and containing some loose mucous flocculi. Loop distended with grey watery fluid containing gelatinous flocculi. Surface of mucous membrane soft, thickened and covered with a gelatinous layer of material similar to the flocculi. Fluid strongly alkaline; smell mawkish and choleraic; contained about £th of albu- men. Flocculi composed of exudation cells. Gelatinous layer on mucous mem- brane composed of similar cells in a mucoid basis. Exudation of fluid ; reddish ; sp. gr. 1,009; alkaline; containing albumen. Loop distended with fluid; pinkish grey; strongly alkaline; odour choleraic; sp. gr. 1,006. Surface of mucous membrane soft, thickened and covered with a loose yellowish layer of exudation cells.
