It has long been known that zoster, in the vast majority of instances, occurs once only in the lifetime of the individual.
Exceptions to this law have, however, from time to time been noted. It is my intention in this paper to give a brief notice of as many of these as I have been able after a diligent search to gather, to classify them according to what seemed the most natural method, and in this way possibly to facilitate a better understanding of their aetiology and pathology.
