The CHONDROMA. 419 granules of chalk form first in the capsules and later in the cells, anddeposition in the intercellular substance takes place later. Cystic degeneration is often found in the interior of the tumor presents a honeycombed appearance from thepresence of numerous small cysts. Coalescence of many cysts resultsin the formation of large irregular cavities. The softening which resultsin the formation of cysts is preceded by fatty degeneration of the carti-lage-cells. Fat-granules appear at different points in the protoplasmof the cells, and the fatty degeneration finally terminates in the dis-solution of the cells. At the same time the intercellular substanceundergoes mucoid liquefaction. Hemorrhage into the cysts resultsin discoloration and pi
