Arthur Conan Doyle,
The land of mist
(1926)
“ The fact that a man was a great physiologist and physicist did not in itself make him an authority upon psychic science.It was perfectly clear that Professor Challenger had not read the standard works upon the subject on which he posed as an authority. Could he tell the audience what the name of Schrenck Notzing’s medium was? He paused for a reply. Could he then tell the name of Dr. Crawford’s medium? Not? Could he tell them who had been the subject of Professor Zollner’s experiments at Leipzig? What, still silent! ”
