he suddenly travelled from Australia to Zürich, where he lived for some weeks in careless cheerfulness, and only came to himself when he read in the paper of his sudden disappearance from Australia. He had a total and retrograde amnesia for the several months which included the journey to Australia, his sojourn there and the return journey.
Azam[1] has published a case of periodic amnesia. Albert X., 12½ years old, of hysterical disposition, was several times attacked in the course of a few years by conditions of amnesia in which he forgot reading, writing and arithmetic, even at times his own language, for several weeks at a stretch. The intervals were normal.

Boileau describes a similar case[3] of wandering-impulse. A widow of 22, highly hysterical, became terrified at the prospect of a necessary operation for salpingitis; she left the hospital and fell into a state of somnambulism, from which she awoke three days later with total amnesia.
