look like a coincidence by the experience
of the same friend. He inhabited, as a young married man, a flat in a
house belonging to an acquaintance. The hall was covered by a kind of
glass roof, over part of its extent. He was staying in the country
with his wife, and as they travelled home the lady was beset with an
irresistible conviction that something terrible had occurred, _not_ to her
children. On reaching their house they found that one of their maids had
fallen through the glass roof and killed herself. They also learned that
the girl's sister had arrived at the house, immediately after the
accident, explaining that she was driven to come by a sense that something
dreadful had happened. The lawyer, too, who represented the owner of the
house, had appeared, unsummoned, from a conviction, which he could not
resist, that for some reason unknown he was wanted there.[1] Here, then,
was not an hallucination, but an emotional effect simultaneously reaching
the consciousness of three persons, and coinciding with an unknown
crisis.[2]

Cases in which a person feels urged to an act (2) are also recorded.
Indeed, the lawyer's in our anecdote is such an instance. Not to trouble
ourselves (3) with 'voices,' hallucinations of sight, coinciding with a
distant unknown crisis, are traced from a mere feeling that somebody is in
the room, followed by a _mental_, or _mind's eye_ picture of a person
dying at a distance, up to a kind of 'vision' of a person or scene, and so
on to hallucinations appealing, at once, to touch, sight, and hearing. As
some hundreds of these narratives of coincidental hallucinations in every
degree have been collected from witnesses at first hand, often personally
known, and usually personally cross-questioned, by the student, it is
difficult to deny that there is a _prima facie_ case for inquiry.[3]

There is here no question of 'spirits,' with all their physical and
metaphysical difficulties. Nor is there any desire to shirk the fact that
many 'presentiments' and hallucinations of the sane coincide with no
ascertainable fact. We only provisionally posit the possibility of an
influence, in its nature unknown, of one mind on another at a distance,
such influence translating itself into an hallucination. An inquiry into
this subject, in the ethnographic and modern fields, may be new but
involves no 'superstition.'

We now return to Mr. Tylor, who treats of hallucinations among other
experiences which led
