The discovery of such sensitiveness in one of the most vigorous men, in mind and body, of his day, led Dr. Buchanan to believe it might be found in many others. It is needless to say his conjecture was correct. Accordingly, in the numerous neurological experiments which he afterwards commenced, he was accustomed to place metals of different kinds in the hands of persons of acute sensibility, for the purpose of ascertaining whether they could feel any peculiar influence, recognise any peculiar taste, or appreciate the difference of metals, by any impression upon their own sensitive nerves. It soon appeared that the power was quite common, and there were a large number of persons who could determine by touching a piece of metal, or by holding it in their hands, what the metal was, as they recognised a peculiar influence proceeding from it, which in a few moments gave them a distinct taste in the mouth. But this sensitiveness was not confined to metallic substances. Every substance possessing a decided taste--sugar, salt, nutmeg, pepper, acid, etc.--appeared to be capable of transferring its influence. The influence appeared to affect the hand, and then travel upwards. He afterwards demonstrated when a galvanic or electric current passed through a medicinal substance, the influence of the substance was transmitted with the current, detected and described by the person operated upon. Medicinal substances, enclosed in paper, were readily recognised and described by their effects. In due time, stranger still, a geological specimen, an article worn, a letter written upon, a photograph which had been handled, a coin, etc., transmitted their influence, and the psychometrist was enabled to read off the history concerning the particular object. Nearly fifty years have elapsed since the discovery of this “strange new science” and art. “To-day it is widely known, has its respected and competent practitioners, who are able to describe the mental and vital peculiarities of those who visit or write them, and who create astonishment and delight by the fidelity and fulness of the descriptions which they send to persons unknown, and at vast distances. They give minute analysis of character and revelations of particulars _known only to the one described_, pointing out with parental delicacy and tenderness the defects which need correction, or in the perverse and depraved they explain what egotism would deny, but what society, family, and friends recognise to be too true.” PSYCHOMETRIC REFLECTIONS.
