I maintain in this connexion, that any case of incipient appendicitis may be treated successfully by these methods. Further, when this position of mechanical advantage has been attained through the employment of the first principles of conscious guidance and control, a rigid thorax may regain mobility, no matter what the age of the subject, and full thoracic expansion and contraction may be acquired and, with the minimum of effort, maintained. During the practical process by which this thoracic elasticity and maximum intra-thoracic capacity is gradually established, the body of the subject is at the same time re-adjusted and mental principles are inculcated which will enable him to maintain the improved conditions in posture and co-ordination which are being set up, and which will secure the normal and necessary abdominal pressure in the right direction, thus constituting a natural form of massage of the digestive organs which is maintained during the ordinary actions of everyday life. 3. I am able to re-adjust and to teach others to re-adjust the human machine with the hands; to mould the body, as it were, into its proper shape, and with an open-minded pupil it is possible to remove many defects in a few minutes, as, for example, to change entirely the production of a voice, its quality and power. 4. In prescribing the principles of conscious guidance and control, we are dealing not with an epidemic of physical or mental degeneracy, but with a stage in the progress of the human race from the subconscious and instinctive to the conscious and reasoned command of the whole human mechanism. In other words, we have reached a stage in the process of civilisation where demands are being made which we are unable to meet satisfactorily, and with the serious results which may be seen on every hand, results from which we can escape only by passing from those primitive modes of guidance which approximate too closely to those of the animal kingdom where the greater potentialities of the human being remain latent. The suggested adoption of conscious guidance and control as a universal principle on the lines heretofore outlined will enable us to move slowly but with gradually increasing speed towards those higher psycho-physical spheres which will separate the animal and human kingdoms by a deep gulf, and mankind will then enjoy the blessings which will be the natural result of capacities fully developed.
