    beginning of the next,—be represented by 10, the value of the duration of the inspiratory move- ment may be estimated approximatively at 5, of the expiratory at 4, and of the pause between the expiratory and succeeding inspiratory movement at 1. [§ 13.] In health, the extent and frequency of the motions of the thorax respectively regulate, or, at least, bear a direct proportion to, the duration and intensity of the pulmonary respiratory murmurs. b. The partial motions of the chest are those of the ribs upon each other. During inspiration these bones rise upwards, and separate somewhat from each other (in other words, the intercostal spaces widen); during expiration they become proportion- ally lowered, and approach nearer to each other. In these movements there is apparently some degree of torsion of each rib. In health, the freedom and extent of these partial movements bear a direct proportion to those of the general thoracic motions; they are more marked in very young subjects than in adults, in these than in persons of advanced age. Morbid States discovered by Inspection. A. Form.—The different changes of form (hete- romorphism) and of position (heterotopia) of the whole chest or of its parts, which may announce subjacent disease, are referrible to the following species [§ 14. ]:— Expansion and Bulging. Retraction and Depression.
