SCIENCE AND THE 'SPIRITS: 



1 1 1HEIK refusal to investigate ' spiritual phenom-

 tempt to apply to the ' phenomena ' those methods of 

 enquiry 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 acquaint-

 so privileged, and he therefore kindly arranged a trans- 

 fer of the invitation to me. The spirits themselves 

 named the time of meeting, and I was conducted to 

 the place at the day and hour appointed. 



Absolute unbelief in the facts was by no means my 

 condition of mind. On the contrary, I thought it prob- 

 able that some physical principle, not evident to the 

 spiritualists themselves, might underlie their manifes-

 accumulation of small impulses. Galileo set a heavy 

 pendulum in motion by the well-timed puffs of his 

 breath. Ellicot set one clock going by the ticks of 

 another, even when the two clocks were separated by a 

 wall. Preconceived notions can, moreover, vitiate, to
