2, Stand before a mirror. See whether or not you are enabled to perceive any influence coming from your reflected image in the mirror. Many sensitive persons can do this, and the more sensitive you are, the more will you feel this. You will sense a magnetic fluid, coming from the reflected form in the mirror.
3. If you are in the habit of sleeping with any one regularly, endeavour to analyse the impressions you receive from the aura emanating from the body of the person with whom you may be sleeping. See whether this is positive or negative. Positive aura is slightly warm, negative aura is somewhat cold.
4. Hold your right hand above a mirror ; then the left hand. Try to feel whether one hand feels cooler than the other; or whether both are of equal temperature. The hand which is warmest is on the more positive side of the body,
5. Close your eyes, and have some one make magnetic passes over your head and shoulders. Try to tell whether those passes are being made in an upward or downward direction. Downward passes are positive or sleeping passes; upward passes are negative or waking passes.
6. Procure several metals, such as copper, iron, tin, zinc, etc. Place your hands over each in turn, and ascertain the different impressions you get from each one. Then wrap them in separate pieces of paper (making all alike in appearance) and see whether you can always tell the correct metal from feeling the paper. Then place your open hand over the paper, without touching it. Next remove your hand gradually further and further away, until you are some distance from the metal. After a time, you should be enabled to do all this from a considerable distance. It is only an extension of this power which enables “dowsers” or metal and water-finders to locate the whereabouts of metal and water under the ground, by walking over the spot, above ground, with hands outstretched, or with a divining or dowsing rod held in their hands.
7. Always have flowers in your sleeping room. They are a good influence. Analyse the difference between your impressions when the flowers are removed; and when they are in the room.

A developing circle should meet in the same room, since this room tends to become ‘ ‘ mediumized, ‘ ‘ or soaked
with magnetic influences, given off by the sitters. The chairs on which the members of the circle sit should be wood or cane-bottomed ; the use of upholstered chairs is generally inadvisable. The table round which the members of the circle sit should be free from metal. The chair on which the medium sits must be cane or wood, and, as already said, free from all cushions or upholstery.
