IN this Work, which we have written chiefly for the information of those who are curious and indefatigable in their enquiries into occult knowledge, we have, at a vast labour and expence, both of time and charges, collected whatsoever can be deemed curious and rare, in regard to the subject of our speculations in Natural Magic.
We have fully explained what Natural Magic is; and have shewn that, by the application of actives to passives, many wonderful effects are produced that are merely natural, and done by manual operations. We have procured every thing that was valuable and scarce respecting this department of our work, which we have introduced under the title of Natural Magic; and a variety of our own experiments likewise. In the possession of this work, the laborious and diligent student will find a complete and delectable companion; so that he who has been searching for years, for this author and the other, will in this book find the marrow of them all.
