(After Timofeew, from Nagel.) a, thick medullated nerve fibre; 6, fine medullated nerve fibre. on the inferior vena cava at the level of the renal veins in the guinea-pig produced a sudden ejaculation. Loeb^ states that he was able to induce contraction of the vasa deferentia by stimulating the hypogastric nerves. Langley ' found that most of the efferent fibres for the vasa deferentia traversed the sympathetic in the region of the 4th, 5th, and 6th lumbar gangha, so that presumably they chiefly arose from the 3rd, 4th, and 5th lumbar nerves.
