A section of the cord taken 2 cm. above the lesion () shows two principal areas of destruction, one in the gray matter of oneposterior horn and the other in the lateral column of the same side. The positionof the posterior horn is occupied by a pyriform-shaped cavity. On the lateral wallof this cavity some of the nerve fibrils of the posterior horn can be seen. Thecavity in the lateral column occupies the position of the spinothalamic tract. Its post. med. ^^^^^4\. Fig. II.—Case 6.

In a similarposition in the opposite lateral column there is an area of degeneration. Oedemais well marked throughout the section. Remarks.—The area of was much greater than we expected tofind from the naked eye characters of the cord. Although the greater part ofthe lateral columns seem to have escaped disintegration, they are seriouslyshattered. The gray matter was completely destroyed for the distance of onespinal segment at the least. It is interesting to note that cavitation was alsopresent in the section taken 2 cm. above the lesion. It is more than probablethat the lesion was anatomically a complete transverse one. The case is particu-larly interesting because there was no direct wound or crush of the cord.
