• "These nuclei are believed to be in connection with a delicate sheath corresponding with the neurolemma of the medullated nerve fiber."
• "The nerve fiber, on approaching the muscular fiber, suddenly loses its medullary sheath, the neurolemma becomes continuous with the sarcolemma of the muscle, and only the axis-cylinder enters the muscular fiber."
• "If the fiber be treated with silver nitrate the reagent penetrates the neurolemma at the nodes, and on exposure to light reduction takes place, giving rise to the appearance of black crosses, Ranvier’s crosses, on the axis-cylinder."
