Every important internal organ is connected, through afferent sympathetic and efferent spinal nerves, with definite skeletal structures, and if inflamed shows reflex sensory and motor actions, and that if the inflammation becomes chronic, important diagnostic trophic changes occur, such as altered sensation and muscle degeneration. For instance, chronic inflammation in the apex of a lung produces reflex degenerative changes in overlying skin, subcutaneous tissue and muscle, which influence percussion, palpation, and auscultation, and must be con-
