Underhill on mesmerism : with criticisms on its opposers, and a review of humbugs and humbuggers, with practical instructions for experiments in the science, full directions for using it as a remedy in disease, how to avoid all dangers : the philosophy of its curative powers, how to develop a good clairvoyant, the philosophy of seeing without eyes : the proofs of immortality derived from the unfoldings of mesmerism, evidence of mental communion without sight or sound, between bodies far apart in the flesh, communion of saints or with the departed / by Samuel Underhill.
