The subject of motility is one of great interest to scientific men in many fields of investigation. Neurologists, particularly, have always had a peculiar interest in motor function and its disorders, and to neuropathology must be credited much that we know of the underlying neural and muscular mechanisms.
During the last half century our knowledge of this important function of the living organism has made great progress and each decade has marked some new advance in the realm of motion, as well as in the sensory sphere. For these two great functions of the living organism are the pillars on which have been reared those marvellous mechanisms of the central nervous system, the phylogeny of which is the story of all organic life.
The problem of motion and sensation must, therefore, ever remain a living issue in the realm of science, as life itself traverses these two pathways side by
