　The purpose of the present experimental spinal　metastasis developed in rats by inoculation of Walker's　cancer cells through the spinous process is to find the　factor which causes the initial damage of the cord in　this disorder．In the early stage of paralysis, microan—giogram exhibited that the degenerated posterior funi—culus originated from the small hemorrhagic area in the　posterior column of the involved cord．Scanning elec—tron microscopic findings showed that the hemorrhage　was of the intrinsic vein resulting from the disturbance　of venous drainage in the compressed portion．
