    Certain anatomical and physiological points pertain to the organs within the chest. The more important of these, relating to normal physical conditions, are the following: 1st, as regards the lungs, the connections of the pleura, and the smoothness of the pleural surfaces in contact with each other; the relations of the apex and base of each lung to the chest-walls, and the differ- ences of the two lungs in this respect; the relative spaces occupied respectively by the two lobes of the left, and the three lobes of the right lung; the situation of the interlobar fissures in either side on the posterior, lateral, and anterior aspects of the chest; the arrange- ment of the air-vesicles, pulmonary lobules, and the different-sized intra-pulmonary bronchial tubes; the ex- pansion of the air-vesicles, and the movement of the current of air from larger to smaller bronchial tubes in the act of inspiration, the vesicles diminishing in size, and the current of air moving from smaller to larger tubes in the act of expiration ; the difference in respect of the relative proportion of air and solids at the end of inspiration and at the end of expiration; the extent to which the volume of the lungs may be diminished by a forced act of expiration, and increased by a forced act of inspiration; the relations of the apices to the sub- clavian arteries, and the variable extent to which the apex rises on either side above the clavicle. 2d, as regards the larynx, trachea, and the bronchial tubes outside of the lungs, the anatomy and physiology of the vocal chords, of the muscles concerned in the move- ments of respiration and of phonation, with the relations of each to the recurrent laryngeal nerve, the size of the rima glottidis in youth, after puberty, and relatively in the two sexes, the enlargement of the rima in the act of
