The Lungs are reservoirs for the air, out of which we make sounds, by condensation. All are familiar with the hand-bellows: observe the striking analogy between it and the body, in the act of speaking, singing and blowing. The wind-pipe is like its nosle, the lungs like the sides, and the abdominal and dorsal muscles, like its handles; of course, to blow with ease and power, one must take hold of the handles; to speak and sing right, the lower muscles must be used; for there is only one right way of doing anything.

14. This is a view of a well developed and naturally proportioned chest; with space for the ungs, the short ribs thrown outwardly, affording ample room for the free action of the organs: it is the true model of the form of one who would live to a good old age.

17. This engraving, of a bell-shaped glass, C, C, shows how the air gets into the lungs, and some of its effects. A head is placed on the cork, T, representing the wind-pipe, and having a hole through Cit. L, represents a bladder, tied to the lower end of the cork, to indicate a lung. At D, is seen the diaphragm. The cavity of the bell represents

the inside of the thorax, where the heart and lungs are: there is no communication with the external air, except through the hole in the cork; air, entering through that hole, can go only into the bladder. Now, when the centre of the diaphragm is raised to D, the bladder will be flaccid and devoid of air; but when it is dropped, to the situation of the dotted line, a tendency to a vacuum will be

15. TIGHT DRESSING. No one can enjoy good the consequence, which can be supplied with air, health, or perform any kind of labor with ease, or only through the hole in the cork; the air expandread, speak, or sing, when the thorax is habitual-ing the bladder to its full extent, is shown by the ly compressed. It diminishes the capacity of the lungs, for receiving the necessary quantity of air to purify the blood, and prevents the proper action of the diaphragm. The following engraving shows

the alarming condition of the chest, when com

pressed by tight lacing; a practice that has hurried, and is now hurrying, hundreds of thousands to a premature grave; besides entailing upon the offspring an accumulation of evils, too awful to contemplate. What is the difference between killing one's self in five minutes with a razor, and doing it in five years by tight lacing, or any other bad habit? Our clothing should never be so tight as to prevent the air from coming between it and the body.

16. Here follows an outline of the chest, or thorax of a female, showing the condition of the bones of the body, as they appear after death, in every one who has habitually worn stays and eorsets, enforced by tight lacing. 'But,' says one, I do not lace too tight.' If you lace at all, you most certainly do, and will, sooner or later, expe

it undergoes a purification: hence may be seen the importance of an upright position, and perfect inflation of the lungs; no one can live out his days without them.

19. Here are two attitudes, sitting, and standing, passive and active. Beware of too much

stiffness, and too much laxity, of the muscles; be natural and easy. Avoid leaning backwards or forwards, to the right or left: and especially, of resting your head on your hand, with the elbow on something else: by which practice, many nave caused a projection of one shoulder, induced spinal affections, &c. Beware of every thing that is improper: such as trying how much you can lift with one hand, &c.

20. Here follows a representation of the position of the diaphragm, and illustrations of its actions, in exhaling and inhaling. Figure 1, in the left engraving, represents the diaphragm in its greatest descent, when we draw in our breath: 2, museles of the abdomen, when protruded to their full extent, in inhaling: 1, in the right engraving, the diaphragm in its greatest ascent in expiration: 2, the muscles of the abdomen in action, forcing the

This engraving represents the larynx, or vocal box, at 1, near the top of the wind-pipe, 2; the bronchial tubes, or branches of the trachea, 3, 4, going to each lung; the left lung is whole; the substance of the right one removed, to show the ramifications of the bronchial twigs, terminating in the air-cells, 7, 7, 8, like leaves on the trees.
