To me the questions involved are intensely interesting, hence my queries. I hope they do not read as if I were hypercritical or sceptical.

We handed the above interesting letter to our contributor, Dr H. Valentine Knaggs, and append his reply:-- HUMAN MAGNETISM. There is very little information available from ordinary scientific sources anent the question of the life-force or of the animal magnetism which animates our bodies and is the motive force common to all organic structures whether animal or vegetable. We do know that fresh fruits and vegetables are strongly magnetic because the magnetism which they emit can be gauged by means of delicate galvanometers. It has been found that leaves, flowers and seeds are positively, and roots negatively, charged. We also know that the same conditions are found in the human subject, since Dr Baraduc, who is a celebrated French Psycho-Therapeutist, in his book, "The Vibrations of Human Vitality," tells us that he has invented a machine called a biometer to test these very vibrations. I have had one of these machines myself and have experimented with it a great deal. By its aid we can make the machine work differently with different persons, and by careful tabulation of records Dr Baraduc has been able to elicit some very remarkable information about the magnetic currents which are constantly flowing into and out of the human body. If our correspondent really wants to know more about the wonders of human magnetism he should read some of the voluminous literature upon the subject published by the Theosophical Society. Just recently also a Dr Kilner has invented a form of coloured screen by which he and others who have some psychic sight can actually see the magnetic emanations which flow through a person placed in a darkened room.
