These two actions, the re-education of the “Kinæsthetic Systems” and the increasing of the thoracic capacity which applies a mechanical power by means of the muscles and ribs to the straightening of the spine, are both aspects of the one central idea, and are not separate and divisible acts. 2. _Appendicitis._ The prevalence of appendicitis has always seemed to me one of the most striking proofs of the inefficiency of present-day methods in regard to health. At times I am filled with wonder that we permit such bad conditions to become established as may necessitate the removal of the appendix. It is, of course, well known that the operation is frequently performed when the conditions do not warrant such extreme measures, but cases have come under my notice, nevertheless, and those not among the uneducated classes, in which the symptoms had become so aggravated by years of harmful habits of life as to necessitate the major operation. Fortunately there is a section of the medical profession which objects, on scientific grounds, to the removal of the appendix in all but extreme cases, and this opposition and the evidence adducible as to the comparative ease with which the exaggerated condition may be avoided and the trouble completely cured by natural means, is doing much to limit the sphere of those champions of the knife who are never content unless they can be dissecting the living body. There can be no question or shadow of doubt that when the whole frame is properly co-ordinated and the adjustment of the body is correct and controlled according to the principles I have enunciated, it is a practical impossibility to get appendicitis. The cause of the trouble is due to imperfect adjustment of the body which allows or forces the abdominal viscera to become displaced and to fall. The first consequence of this is a change of pressures and the loss of the natural internal massage, present in normal conditions. This leads to constipation among other symptoms, and permits the gradual accumulation of toxic poisons. When the trouble has already shown itself and there is some positive inflammation of the appendix and tenderness in that region, it is by no means too late to apply my methods. The new co-ordinations which may in such cases be brought about very quickly, and established later, at once relieve false internal pressures and permit a natural re-adjustment of the viscera, and the furtherance of a rapid return to a healthy and normal condition is greatly accelerated by the internal massage. With regard to this latter treatment to which I have already referred in this chapter, I may mention that many pupils have asked me if I use internal massage in my system of re-education. In my brochure on the _Theory and Practice of Respiratory Re-education_, included in Part III, it will be found that I used this description, as I said, for lack of one that was sufficiently comprehensive, but the principle itself is one of the first importance.
