About eighteen years ago a lady in Swansea sent me a lock of hair, and asked me to send her my impressions. I did so, which I remember were not pleasant. I informed her, as near as my recollection now serves, that the person to whom the hair belonged was seriously ill. No earthly skill could do anything for him. Diagnosing the character of the insidious disease which was then undermining a once powerful and active organisation, I felt constrained to add he _would live six weeks_. I held the envelope, with its contents, in my left hand, and wrote the impressions as they came with my right. I remember hesitating about sending that letter, but eventually sent it. The accuracy of my diagnosis, description of the patient, and the fulfilment of the prophecy as to his death were substantiated in a Swansea paper, _The Bat_. The patient was no other than Captain Hudson, the British master mariner who sailed the first ship on teetotal principles from a British port, and who subsequently became one of the most powerful of British mesmerists. The lady who sent the lock of hair was his wife, and the lady who contributed the letter to the papers was his widow. Of similar experiences Mrs. Coates and I have had many. HOW TO CULTIVATE THE PSYCHOMETRIC FACULTY. _Class Experiments._--The sensitives are not to be magnetised or unduly influenced by positive manner and suggestions, but are to sit in their normal state (and without mental effort or straining to find out what they have in their hands), and simply give expression to their impressions--sensations, tastes, etc., if any, and no matter how strange to them these may be. Let the experimenter or operator place different metallic substances in their hands, taking care that these substances are carefully covered with tissue paper or other light substance, which will help to hide their character, and at the same time not prevent their influence being imparted, or try them with medical substances. In those sufficiently sensitive, an emetic will produce a feeling of nausea. The substance must be put down before it causes vomiting. Geological specimens can be given--a shell, a tooth, or tusk. Let the experimenter record the utterances patiently, and seek confirmation of the description from an examination of the specimen subsequently. He should not know what special specimen it is previous to the psychometer’s declared opinion. Good specimens are best. Thus a fragment of pottery, a piece of scori, or a bit of brick from, say, Pompeii would present material from which the psychometrist could glean strong and vivid impressions.
