'Passing upward at once without further description to the level of the 2nd thoracic nerve-root (Fig. 14) the following condition is discovered by the sections. A wide band of comparatively slightly degenerated tissue extends between the area of absolute degeneration and the posterior horn. If the whole area of the posterior column measures about 1050, the absolute degeneration in it measures 366. The area of absolute degeneratioin is wedge-shaped and extends a good half way toward the posterior commissure; and engages more than half (4/7) the free edge of the posterior column.' (278)
