Due regard must be given to non-neurological affections in the thorax which might modify the action of the intercostal muscles and diaphragm. Five groups of variations which are of neurological import are recognized. The first group shows exaggerated lateral movements of both costal margins and includes the cases of paralysis of the diaphragm, such as may occur in poliomyelitis and other lesions of the second, third and fourth cervical segments due to
