Fig. 209 shows a syphilitic exostosis of left side of vault ofskull. In Fig. 210 the right tibia and fibula present irregularity and generalthickening of compact tissue, with abundance of exostotic growths. Some-times the growth projects and appears to be superadded to the bone, as theepiphysis of a long bone, and, being movable upon the bone beneath, isknown as an epiphysary exostosis. Occasionally the syphilitic exostosis isthe result of an osteitis that terminates in hypertrophy of the normal bone,.

Exostoses springingfrom the inner table of the skull or occurring in the spinal canal may, bypressure upon the brain, cord, or nerves, give rise to various forms of paral-yses, convulsions, and neuralgia?.

The lesions are seen in the form of tumors,varying in size and having a tendency to become caseous during some periodof their evolution (Cornil).
