all be subjected by any one to the same
hallucination, by an unuttered command, is a thing unknown to science,
and most men of science would deny that even one single person could
be hallucinated by a special suggestion not indicated by outward word,
gesture, or otherwise. We read of such feats in tales of 'glamour,'
like that of the Goblin Page in _The Lay of the Last Minstrel_, but to
psychological science, I repeat, they are absolutely unknown. The
explanation is not what is technically styled a _vera causa_. Mr.
Aide's story is absolutely unexplained, and it is one of scores,
attested in letters to Home from people of undoubted sense and good
position. Mr. Myers examined and authenticated the letters by post
marks, handwriting, and other tests.[22]

In one case the theory of hallucination induced by Home, so that
people saw what did not occur, was asserted by Dr. Carpenter,
F.R.S.[23] Dr. Carpenter, who was a wondrously superior person, wrote:
'The most diverse accounts of a _seance_ will be given by a believer
and a sceptic. One will declare that a table rose in the air, while
another (who had been watching its feet) is confident that it never
left the ground.' Mr. Aide's statement proves that this explanation
does not fit _his_ case. Dr. Carpenter went on to say what was not
true: 'A whole party of believers will affirm that they saw Mr. Home
float in at one window and out at another, whilst a single honest
sceptic declares that Mr. Home was sitting in his chair all the
time.'[24] This was false. Dr. Carpenter referred to the published
statement of Lord Adare (Dunraven) and Lord Lindsay (the Earl of
Crawford), that they saw Home float into a window of the room where
they were sitting, out of the next room, where Home was, _and float
back again_, at Ashley Place, S.W., December 16, 1868. No 'honest
sceptic' was present and denied the facts. The other person present,
Captain Wynne, wrote to Home, in a letter printed (with excisions of
some contemptuous phrases) by Madame Home, and read in the original
MS. by Mr. Myers. He said: 'I wrote to the _Medium_ to say I was
present as a witness. I don't think that any one who knows me would
for one moment say that I was a victim to hallucination or any humbug
of that kind.' Dr. Carpenter, in 1871, writing in the _Quarterly
Review_ (Vol. 131, pp. 336, 337), had criticised Lord Lindsay's
account of what occurred on Decembe
