This is a short ebook in the Hadean Press tradition. It's very useful. The author does just what they promise: the fumigations from Agrippa's "Three Books of Occult Philosophy" are taken apart and analyzed, with alternate ingredients given. One very nice thing about the book is that it also includes a fumigation for all seven planets all mixed together! I particularly appreciated how they were kind enough to point out all of the poisonous ingredients and which ones should not be burned anywhere near human nostrils.
