'It is not intended to make take the place of boxing, fencing, wrestling, savate, or any other recognized forms of attack and defence. This, however, is claimed for it- it comprises all the best points of these methods, and will be of inestimable advantage when occasions arise where neither boxing, nor wrestling, nor any of the known modes of resistance is of avail. The system has been carefully and scientifically planned; its principle may be summed up in a sound knowledge of balance and leverage as applied to human anatomy.'
