Interesting find from early 1900s.. The author states in his preface:
MAGIC, white and black, was originally written at a time when I imagined that it was possible by means of intellectual efforts to bore a hole through the veil that cover the mystery of the spirit, and the favor with which the first three editions have been received I attribute to the generally prevailing curiosity of obtaining a knowledge of spiritual things without having to pass through the slow process of becoming spiritual oneself. As it has been decided to bring out a new edition, I have attempted to remedy its most conspicuous faults, and to make such improvements as were suggested by a more extended experience. In this new shape I can conscientiously recommend it to my American compatriots, and to all who are interested in the study of occultism.
