We might continue this article to an indefinite length; but as we shall, in the following pages, have occasion to refer to the use of the lancet as a destructive agent, we conclude it with the following remarks of an English physician: "Our most valuable remedies against inflammation are but ill adapted for curing that state of disease. They do not act directly on the diseased part; the action is only indirect; therefore it is imperfect. Bleeding, the best of any of these remedies, is in this predicament."

"Nature is ever busy, by the silent operations of her own forces, in curing disease."--_Dixon._ Whenever any irritating substance comes in contact with sensitive surfaces, nature, or the _vis medicatrix naturæ_, goes immediately to work to remove the offending cause: for example, should any substance lodge on the mucous surface, within the nostril, although it be imperceptible, as often happens when the hay is musty, it abounds in particles whose specific gravity enables them to float in atmospheric air; they are then inhaled in the act of respiration, and nature, in order to wash off the offending matter, sends a quantity of fluid to the part. The same process may be observed when a small piece of hay, or other foreign matter, shall have fallen into the eye: the tears then flow in great abundance, to prevent that delicate organ being injured. "When a blister is applied to the surface, it first excites a genial warmth, with inflammation of the skin; and nature, distressed, goes instantly to work, separates the cuticle to form a bag, interposes serum between the nerves and the offensive matter, then prepares another cuticle, that, when the former, with the adhering substance, shall fall off, the nervous papillæ may be again provided with a covering. "The same reasoning will apply to the operation of emetics and cathartics; for not only is the peristaltic motion either greatly quickened or inverted, according to the urgency of the distress, but both the mucous glands and the exhalent arteries pour forth their fluids in abundance to wash away the offending matter, which at one time acts chemically, at others mechanically." If a horse, or an ox, be wounded in the foot with a nail, and a portion of it is broken off and remains in the wound, inflammation sets in, producing suppuration, and the nail is discharged.
