The adventitiousgrowth is developed in the interior of the formation gradually takes place in the can-cellous texture; and the external portion, orshell, proportionally dilates. This outer shell,though attenuated by distention, yet receives addition of new osseousmatter from time to time ; and long retains its continuity. Ultimately, 1 Muller. Fig. 147.

This variety, then, isinvested by both bone and periosteum ; and it is that which most fre-quently occurs. 2. The second variety is formed on the exterior of the bone; and iscovered only by the periosteum and other soft parts. It is generallymet with in the flat bones; cranium, pelvis, and ribs. The interior of thetumour is the same as that of the preceding; the form is less regularlyspheroidal, and the surface is more unequal. Treatment.—When enchondroma is very small and recent, there issome reason to believe that discutients, such as mercury and iodine, maynot only check but gradually disperse the tumour. In the greatmajority of cases, however, though this be little disposed to degenerate,still it is in no way amenable to absorption; and therefore it demandsremoval by the knife.
