    The removal of the rahbit-labyrintli. The section of the N. oclavus and of its prolongation in the central nerve-system. The disturbances of motion following on these operations. I. A few teclinical remarks on the removal of the lahyrintlL in rahtnts. Before trying to remove the labyi-iiitli of rabbits, it is advisable to learn this operation on pigeons, all the while following strictly the technical directions, described with so minute a preciseness by EwALD, without neglecting any of the details given by him. If the removal of the labyrinth is performed with the ])urpose of investigating, after a more or less prolonged duration of life of the animal, the secundary degenerations and atrophies in the central nerve-system by means of the methods of Marchi or Gudden, it is of the utmost impo]tauce to take care that no accessory lesion may occur. For the same reason, with pigeons likewise as with rabbits, the most careful antisepsis in the preliminary stage of the operation and the strictest asepsis during its course are necessary, and some subordinate parts of it ought to be executed with great circum- spection. On the one hand, it is of absolute necessity to avoid any bleeding during the operation. On the other hand the method of the cauterizing the blood-sinus offers a danger, even when following strictly the rules prescribed by Ewald. This danger is that the heat, passing through the bone, may have scorched at a distance the surface of the cerebellum and may thus have created the origin of a secundary degeneration. And a pigeon, having a superficial lesion of the cerebellum even though this may not be betrayed
