1. Forty-five cases of zoster paralysis, not involving the cranial nerves, are detailed. These include eighteen cases not previously published. Of these eighteen patients, one-third were referred for an orthopaedic opinion.

2. Complete or almost full recovery occurred within a year in two-thirds of the patients. Permanent paralysis occurred in one-sixth of the patients studied.

3. Muscles that failed to recover were mainly or wholly supplied from single segments of the spinal cord; so the prognosis must be guarded in those cases in which such muscles are completely paralysed.

4. Various phenomena occurring in zoster paralysis are discussed.
