In every stage of consumption, but especially in the early part of the disease, the patient should exercise the lungs as much as possible, by drawing deep inspirations of air, and inflating the organ to its fullest extent, and then slowly expiring what he has imbibed, repeating the process for ten minutes at a time, and resuming it four or five times a day. For this purpose he can either stand at a window, on a hill, or wherever the air is pure; when the atmosphere is damp, the air must be drawn through a veil, folded three or four times. This makes an infinitely better respirator than the metallic ones sold in the shops. As the natural stimulant of the lungs is air, no means are so likely to excite absorption of the tuberculous matter, as that which expands every air cell of its structure, and while healthily exercising the organ, stimulates it to increased action. That consumption is curable, is a theory now rapidly gaining ground; but this can only be effected by converting the acute into a chronic disease, and in that form following the admonitions of nature as a guide to the practice; and the most important of these is exercising the lungs themselves. SCROFULA. A peculiar condition of the body, in which the healthy vital energy is in a measure in abeyance, where the system is less strong, the body less perfect, the organization less harmonious, and the living power to resist accidents less perfect and capable of resisting those influences of time, air, contagion, and accident, ever at war on the frame of man, and which robust health may rebut and for a time defy, but before which the less perfect organization of scrofula ultimately succumbs. It is to this unnatural weakness of the constitution that we owe many of those diseases and ills that like a scourge afflict mortality; such as consumption, mesenteric disease of the bowels in children, rickets, goître, cretinism, hare-lip, white swellings, and many other local and constitutional maladies; all deriving their origin from this physical and specific weakness of the whole or a part of the human body. Any chronic swelling of the absorbent glands is denominated scrofula, as shown both by the wen in the throat and the white, shiny, and insidious swellings in the knee; yet neither of them is, correctly speaking, scrofula, but merely the local evidence of something we feel and know, but cannot define in the system, couched in the blood, reflected in the want of general nervous energy, and manifesting itself in some local character, to which science gives a name and unprofessional wisdom assigns the disease. The chief characters by which a scrofulous diathesis is known or may be suspected, are a want of perfect bodily symmetry, small, thin, or crooked limbs, a round or pigeon-breast, excessive enlargement of certain organs, broad jaws, low forehead, long neck, and large occiput, great transparency of the skin, with a rosy tint of the cheeks; when the complexion is dark, it
