psychology, and its practical value to both mental and bodily thera- 
peutics is admitted. Less attention is given to its importance to psy- 
chological science, and hence to philosophy. No support is given to 
the rather uncritical assertions frequently made as to the evidence 
offered by hypnotism for the existence of double or multiple personality 
of a single human individual. Not much space is given to the remark- 
able structural changes seen in the formation of red or necrobiotic 
figures on the skin, as the result of suggestion, although the reality of 
the phenomena is not challenged. The experiments of Jendrassik and 
Krafft-Ebing seem to place the facts beyond doubt. 
. Suggestibility is regarded as the principal characteristic of hypnosis 
as distinguished from somnambulism ; hence most of the book is occu- 
pied with an elucidation of its mental and physical implications. Post- 
hypnotic suggestion receives a large share of attention. As an expert 
the author does not occupy so much space with the detailed accounts 
of experiments as with explanations of them in relation to other and 
normal mental states. The work is well adapted to enlighten the 
reader as to the essential significance of hypnotism. The citation of 
authorities is very full.—C. 
Was it Hallucination ?—I had a strange experience about nine 
o'clock this morning, which I hasten to put on record while all its 
details are fresh in my mind. My wife being quite seriously ill, I 
went for our family physician, about three blocks distant. I met him 
in an apothecary’s shop, and asked him to come to our residence. He 
had one call to make near by, but promised to be with us very soon. 
I returned in a few minutes, coming into our cross-street at the east 
end of the block. As I came across a vacant lot just east of our house 
I happened to look out to the westward, when I saw our doctor just 
leaving the cross-walk and turning in as if to come straight to our 
place. It occurred to me that he was a little ahead of the time I ex- 
pected him; but I hurried on to apprise my, wife of his coming. I 
then went out to meet him. But mo one was in sight; and at the 
moment I believed I saw him he was actually in a distant part of the 
town, at least several blocks away. He was detained, and did not 
reach us for a couple of hours, and was much surprised “ my ster 
ment of having seen him. He said it was some sort of pore 
tion, ’—whatever that might be! He asked: “ Was I not apek 
about him?’’ Possibly I was, but with no idea of seeing him t ia 
_ and then, As to the man, I could not be mistaken. His dress, . 
long, flowing, almost white beard—every detail of his personal appear
