This book by Georg Conrad Horst is titled Zauber Bibliothek, it is a German book about the occult, and     it was published in Mainz by Florian Kupferberg in 1825. It is a textbook of magic, spells, rituals and instructions for summoning spirits, angels, and demons and it served as a manual for practitioners of magic - a favorite of followers of the occult. 
The previous lot had the same title and same author and publisher, but that book was published in 1821, and Zauber Bibliothek was considered one of the "three great classics on spirits" from the Goethe era, and again, the text is entirely in German. 
In English, the title page reads “Magic Library, or sorcery, theurgy and manticism, witches and witch trials, demons, ghosts, and apparitions”, so it dealt with magic, summoning demons, incantations, and spirits, theurgy was the attempt to establish a connection between people and the spirit world, and manticism     was the practice and belief in divination and prophecy, i.e. the art of telling and gaining supernatural insight into the future.
Below the author’s name on the title page, it reads “Omnibus aequa”, which means “equal to all”, a motto related to the concept of death, and it reflects the view that death happens to all of us, no matter what our status in life, and this moralizing lesson that everyone shares the same fate evolved in ancient times and ran all the way up through the Baroque period. 
The book has brown boards, a black label with a gilt title and gilt rules on the spine, “G F Kloz” in gilt at the bottom of the spine, blank endpapers, then the title page with “Gottleib Friedrich Kloz” clearly signed towards the bottom and “Mainz 1825 by Florian Kupferberg” in German below that, a four-page Table of Contents, two pages about Moses and a biblical passage connected to Christian witch trials, then 41 pages about scientific treatises which investigate these witch trials, including Hebrew on page 29 from Genesis 6:1, 31 pages about the connection between humans and the spiritual world (pages 42 - 72), then another section about Moses and the Hebrews in Egypt (pages 73 - 126), a fourth section that sums up the previous three sections, including the possibility of sexual intercourse between gods and spirits (pages 127 - 138), then a section about important magic writings (139 - 200), a section about revisions to witches’s trials, including alleged devil possessions and the execution of a woman named Maria Reneta who was burned in 1749 as the last witch in Germany (201 - 264), a section about ghosts (265 - 318), including a 1685 account of a noblewoman named Philippina Agnes von Eberstein who was tormented by a spirit that pinched her arms and hands and left her with pain and bruising, a section of stories about the belief in magic and spirits (319 - 420), including a figure of a mandrake doll called “Imaguncula Alrunica”, which was a mandrake root or talisman that looked like a human, a fold-out astrological chart at the rear about the life and death of King Gustavus Adolphus of Sweden (1594 - 1632),  there are numerous footnotes throughout, and all the pages and images are present.  
The book is in very good condition for its age. It measures 8 1/2 x 5 inches wide, with a tight binding, light rubbing on the gilt rules, light wear along the edges of the spine and at the tips, with a small hole near the heel, Gottlieb Feredrich Kloz’s name is very clear on the title page, there are modest corner creases, brown spots here and there, a curled edge on pages 417 and 419, and overall the book is in very condition for its age.  
WorldCat shows this as volume five of the six volume set (published between 1821 and 1826), only four sites have the book in their Special Collections around the world, and all are located in Germany: at Landesbibliothek Oldenburg in Oldenburg, Hochschul-und Landesbibliothek in Wiesbaden, Niedersachsische Staats-und Universitätsbibliothek Göttingen in Gottingen, and Landesbibliothek Mecklenburg-Vorpommern Günther Uecker im Landesamt fur Kultur und Denkmalpflege in Schwerin; one is a digital copy located at Herzog August Bibliothek Wolfenbuttel in Wolfenbuttel; one copy from 1825 is listed at Gottfied Wilhelm Leibniz Bibliothek in Hannover, and four copies are listed at others sites in Germany, but when we checked, the book is not listed in their holdings (at Staats-und Universitätsbibliothek in Hamburg, Wiessenschaftliche Stadtbibliothek in Mainz, Deutsche Nationalbibliothek Frankfurt am Main in Frankfurt, and Philosophisch-Theologische Hochschule Sankt Georgen Bibliothek in Frankfurt, so the book apparently is rare and hard to find, whether in the set of six from 1821 to 1826 or as a single copy all by itself. 
There aren't many auction or sales records for the book. As stated in the previous lot, Invaluable sold a three-volume set (six volumes in three bindings) for €1200 in 2010 (about $1600) and a six-volume set for €2600 in 2021 (about $3100), and the rare book website we use is selling one copy from 1825 for $214, two seven-volume sets from 1979 are selling for $216 and $294, and we are starting the bidding low for this important piece of occult German literature to get the bidding going.
