It is advisable to have flowers in the seance room, whenever possible, as their presence is said to attract spirits in a peculiar manner. The “spirits” say that they see these flowers as “lights.” Plenty of fresh air should be allowed to enter the seance room. If any member of the circle be ill, he or she should not be permitted to sit in the circle until well again.
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.
