The Book
Kathleen Goligher was a physical medium. In her presence tables levitated and raps ranging from gentle taps to “sledge-hammer blows” were heard.

W. J. Crawford was a mechanical engineer. He turned his keen intellect to investigating Kathleen over a period of several years.

This book is that investigation. It contains 87 experiments along with 39 diagrams. With the cooperation of the spirit operators he established exactly how levitation phenomena works.

Do they defy the laws of gravity? What happens to the weight of the table when it is suspended in the air with no visible means of support? Crawford answered these questions through scientific investigation.

This is not a light read, but a must read for those interested in understanding physical mediumship.
