FLEXIFOBM NEUROMA 143 the nerve-roots are thickened throughout, and that thenodosities are local exaggerations. The details of this casewere recorded by Sibley in 1866. Any nerve, cranial or spinal, is liable to this disease,but among the cranial set it shows marked preferencefor the vagus and the trigeminus. It may affect partsof several nerves, or be limited to certain branches of asingle nerve. The roots of nerves and terminal twigs may be attackedas well as their trunks; and the branches of nerves within themuscles may display nodosities. The sympathetic nerves donot escape, for the great lateral cords as well as the visceralbranches may be nodular with this disease, (Alexis Thomson.)
