In his opening address before the British Association at Edinburgh this year (1871), Sir William Thomson said, "Science is bound by the everlasting law of honor to face fearlessly every problem which can fairly be presented to it." My object in thus placing on record the results of a very remarkable series of experiments is to present such a problem, which, according to Sir William Thomson, "Science is bound by the everlasting law of honor to face fearlessly." It will not do merely to deny its existence, or try to sneer it down. Remember, I hazard no hypothesis or theory whatever; I merely vouch for certain facts, my only object being--the _truth_. Doubt, but do not deny; point out, by the severest criticism, what are considered fallacies in my experimental tests, and suggest more conclusive trials; but do not let us hastily call our senses lying witnesses merely because they testify against preconceptions. I say to my critics, Try the experiments; investigate with care and patience as I have done. If, having examined, you discover imposture or delusion, proclaim it and say how it was done. But, if you find it be a fact, avow it fearlessly, as "by the everlasting law of honor" you are bound to do. In this part of his work Professor Crookes recalls the experiments of Count de Gasparin and of Thury (detailed above) on the phenomenon of the movement of bodies without contact, a thing proved and demonstrated. We need not recur to that. He adds that the ecteneic force of Professor Thury and psychical force are equivalent terms, and that the nervous atmosphere or fluid of Dr. Benjamin Richardson also belongs here. Professor Crookes sent his observations to the Royal Society, of which he is a member. The society refused his communications. The evidence goes to show that it had only approved of the gifted chemist's mixing in heretical and occult researches on consideration of his demonstrating the fallacy of all those prodigies. [Illustration: FIG. 4.] [Illustration: FIG. 5.] Professor Stokes, the secretary, refused to consider the subject at all, or to inscribe even the title of the papers in the society's publications. It was an exact repetition of what took place at the Academy of Science in Paris in 1853. Professor Crookes scorned these arbitrary and anti-scientific judgments and denials and answered them by publishing the detailed description of his experiments. The following are the essential points of this description: [Illustration: FIG. 6.] On trying these experiments for the first time, I thought that actual contact between Mr. Home's hands and the suspended body whose weight was to be altered was essential to the exhibition of the force; but I found afterwards that this was not a necessary condition, and I therefore arranged my apparatus in the following manner:
