This is a german book with the title Das Geistliche Rauchwerck the english translation is: The spiritual incense or the doctrine of prayer after the guidance of the saint. It was printed in 1734 in Hamburg. It appears like Erdmann Neumeister is the author.  I admit I don't know much about the book but I could find no other copies listed anywhere. Very thick book. The first few pages are getting a little weak and are separating slightly from the text block. All pages are attached. 1608 pages plus about 30 page register.  Nice original vellum binding I think it is impressive. Questions please ask
