interesting object of pity what she might have been! Dr. Dewar also relates the case of an ignorant servant-girl, who, during the paroxysm of somnambulism, showed an astonishing knowledge of geography and astronomy, and expressed herself, in her own language, in a manner which, though often ludicrous, showed an understanding of the subject. The alteration of the seasons, for example, she explained by saying the world was set _a gee_. In many cases of somnambulism the sleeper is able to continue the occupation that he had previously carried on. Martinet mentions a watchmaker's apprentice, whose paroxysm came on once in the fortnight, and commenced in a sensation of heat ascending to the heart. This was followed by a confusion of thought and insensibility. His eyes were open, but fixed and vacant, and he was totally insensible to every thing around him. Yet he continued his usual employment, and was always much surprised when he awoke to find the progress that had taken place in his work. This case ended in epilepsy. Horstius, whom we have already quoted, tells us of a noble youth of Breslau, living in the citadel, who used to steal out of a window during his sleep, muffled up in his cloak, and ascend the roof of the building, where one night he tore in pieces a magpie's nest, wrapped up the little ones in his cloak, and returned to bed. The following morning he mentioned the circumstance as having occurred in a dream, but could not be persuaded of the reality of the circumstance till the magpies in the cloak were shown to him. Dr. Abercrombie has given a very remarkable case of a young woman of low rank, who, at the age of 19, became insane, but was gentle, and applied herself eagerly to various occupations. Before her insanity she had been only learning to read and to form a few letters; but during her lunacy she taught herself to write perfectly, though all attempts of others had failed; she had intervals of reason, which frequently continued three weeks and sometimes longer. During these she could neither read nor write, but immediately on the return of her insanity, she recovered the power of writing and reading.
