CHAPTER XXII. 



THEIR refusal to investigate " spiritual phenomena " is 

 often urged as a reproach against scientific men. I here 

 propose to give a sketch of an attempt to apply to the 

 "phenomena" those methods of inquiry which are found 

 available in dealing with natural truth. 



Some years ago, when the spirits were particularly active 

 in this country, Faraday was invited, or rather entreated, 

 by one of his friends to meet and question them. He had, 

 however, already made their acquaintance, and did not 

 wish to renew it. I had not been so privileged, and he

Absolute unbelief in the facts was by no means my con-

 ^ Extraordinary eifects are produced by the accumulation of 

 small impulses. Galileo set a heavy pendulum in motion 

 by the well-timed puffs of his breath. Ellicotsetone clock

 were separated by a wall. Preconceived notions can, more- 

 over,, vitiate, to an extraordinary degree, the testimony of 

 even veracious persons. Hence my desire to witness those 

 extraordinary phenomena, the existence of which seemed 

 placed beyond a doubt by the known veracity of those who 

 had witnessed and described them. The meeting took

 It was therefore requested that the tables and chairs should 

 be examined before her arrival^ in order to be assured that
