Acidus - A method for thought reading. Acidus is the key to varied miracles. It can be used in a design duplication effect or in a question answering act, or the living and dead test.This is booklet is a limited edition of 200 books.

From the back cover:
"Arthur Buckley and John Brown Cook wrote their GEMS in 1947 and no other book comes close to their effort. Over 30 complete routines are presented with such clarity that anyone who wishes to add a new dimension to his act need only adapt the routines to his style."

This was the first book Annemann wrote. It has a glowing introduction by Al Baker, although later in their lives Al and Ted were not always the best of friends. As Annemann himself writes in the foreword, you will find routines employing simple methods and direct to-the-point presentations. This is mentalism at its best without any clutter confusing the effect. A few rare photos of Annemann performing can be found as well.
