In exceptional cases the cells assume a spindle shape. Owing to the delicate structure of the reticulum and its great vas-cularity, ghoma is a soft tumor, and when centrally located in the brainis globular in shape. Gliomata sometimes have a well-defined border,but more frequently it is impossible to determine where the tumorends and the healthy tissue begins. They are found most frequentlyin the posterior segment of the lateral ventricles, but they may occur inany part of the brain and spinal cord, and not infrequently they attain. 548 PATHOLOGY AND TREATMENT OF TUMORS. the size of a fist or a childs head before death ensues. The tumor isgrayish-white in color, with reddish-pink lines indicating the locationof the blood-vessels. Klebs and Bertheau insist that the nerve-cells
