"Magic" by Ellis Stanyon.

Stanyon was one of Britain's finest sleight-of-hand exponents in the twentieth century. In this book he gives detailed instructions on how to perform well-known illusions, as well as many new ones of his own invention. There is also a chapter on Shadowgraphy.

It is very unpleasant to have to refuse an encore; and should you be called upon to repeat a trick study to vary it as much as possible, and to bring it to a different conclusion.
