A great modern French scientist has made many exhaustive studies of these aura, and claims to have photographed them. In the Panama-Pacific Exposition, one of the exhibits contained a series of interesting pictures, or diagrams, which purported to be exact representations of the various aura of people under different mental conditions. In an article on this subject, written by a well-known authority, we are told that: It is not around the human body alone that an aura is to be seen; a similar cloud of light surrounds or emanates from animals, trees, and even minerals, though in all these cases it is less extended and less complex than that of man. The occultists assert that the aura is extremely complex in its character, in other words, that there are several aura superposed one upon the other. The first appearance is of a luminous cloud, extending some eighteen inches or two feet from the body, assuming a somewhat oval shape. Careful study, however, reveals that this first appearance is resolvable into several component parts, or separate aura, of different degrees of tenuity, and, apparently, superposed. Five of these have been defined. The first, or most material, is that pertaining to the physical body. In a state of health this is composed of separate, orderly, and nearly parallel lines, which radiate from the body in every direction. When one suffers from disease the lines in the neighborhood of the part affected become erratic, and radiate less actively but in the wildest confusion, or, if the whole body be affected, all the lines are consequently erratic. For a long time it was not known what kept these lines straight and approximately parallel in the case of the healthy person, until a second radiating aura was discovered. This comes from a healthy body in pulsating waves, with such vigor as to compel the rigidity of the health lines. These waves may be compared to the pulsations of the heated air which rise from the ground on a very hot day. Baron Reichenbach made experiments with certain sensitives who declared they could see these radiations, and he called them "the magnetic flame." When these "waves" come from a sickly or weakly body they not only lose power, but seem to give a confused direction to the health lines.
