However, at Dr. Brinton's suggestion, Mr. Keely took up a line of research that was new to him, and succeeded in making a needle of the three metals, gold, silver and platinum, rotate by differential molecular action; induced by negative attractive outreach, which is as free of magnetic force as a cork. Professor Brinton had so mastered Keely's working hypotheses as to say, early in April, that he was sure he could make them understood by any intelligent person--writing of them: "All that is needed now is to show that Keely's experiments sustain the principles that underlie these hypotheses. As soon as Professor Koenig is prepared to report on the purely technical and physical character of the experiments, I shall be ready to go into full details as to their significance in reference to both matter and mind. It will be enough for me if Dr. Koenig is enabled simply to say that the force handled by Keely is not any one of the already well-known forces. Let him say that, and I will undertake to say what it is." On the evening of the 13th of April, the Provost of the University of Pennsylvania, with others who were invited, met at Mrs. Moore's house to hear the report of the "observation" of Mr. Keely's researching experiments. The result was not made public; as it was desired, by all concerned, that nothing should be made known which could in any way influence the price of the stock of the company, to which Mr. Keely is under obligations; and which, as far as marketable value is concerned, is quite worthless until his system is completed to that point where some one device or machine can be patented. But, after Professor Koenig had made his report to those assembled, and Professor Brinton had read his abstract, all that had been asked for Mr. Keely, in behalf of the interests of science, was conceded to him. Mr. Keely has been able to continue his researches, up to the present time, without the delays which actions-at-law would have occasioned. Professor Brinton, before making public his "Abstract of Keely's Philosophy," wishes to add two parts, one on the difficulties in the way of physicists in understanding Keely's theories; the other on the relations of the conditions of the inter-etheric order to the laws of mind.
