Dr. Walter J. Kilner, The Human Atmosphere

HARDLY one person in ten thousand is aware that he or she is enveloped by a haze intimately connected with the body, whether asleep or awake, whether hot or cold, which, although invisible under ordinary circumstances, can be seen when conditions are favourable. This mist, the prototype of the nimbus or halo constantly depicted around saints, has been manifest to certain individuals possessing a specially gifted sight, who in consequence have received the title of "Clairvoyants," and until quite recently to no one else. This cloud or atmosphere, generally termed the AURA, is the subject of this treatise, in so far as it can be perceived by the employment of screens containing a peculiar chemical substance in solution. It may be stated at once that the writer does not make the slightest claim to clairvoyancy; nor is he an occultist; and he specially desires to impress upon his readers that his researches have been entirely physical, and can be repeated by any one who takes sufficient interest in the subject.
