"Man acts strangely. Although a current of fresh air is the very life of his lungs, he seems indefatigable in the exercise of his inventive powers to deprive himself of this heavenly blessing. Thus, he carefully closes his bed-chamber against its entrance, and prefers that his lungs should receive the mixed effluvia from his cellar and larder, and from a patent little modern aquarius, in lieu of it. Why should man be so terrified at the admission of night air into any of his apartments? It is Nature's ever-flowing current, and never carries the destroying angel with it. See how soundly the delicate little wren and tender robin sleep under its full and immediate influence, and how fresh and vigorous and joyous they rise amid the surrounding dew-drops of the morning. Although exposed all night long to the heaven, their lungs are never out of order; and this we know by daily repetition of the song. Look at the new-born hare, without any nest to go to. It lives and thrives and becomes strong and playful under the unmitigated inclemency of the falling dews of night. I have a turkey full eight years old that has not passed a single night in shelter. He roosts in a cherry-tree, and is in primest health the year through. Three fowls, preferring this to the warm perches in the hen-house, took up their quarters with him early in October, and have never gone to any other roosting-place. The cow and the horse sleep safely on the ground, and the roebuck lies down to rest on the dewy mountain-top. I myself can sleep all night long, bareheaded, under the full moon's watery beams, without any fear of danger, and pass the day in wet shoes without catching cold. Coughs and colds are generally caught in the transition from an over-heated room to a cold apartment; but there would be no danger in this movement, if ventilation were properly attended to,--a precaution little thought of nowadays." Dr. James Blake advises the consumptive to join with several friends, procure horses and wagons, and set off upon a long journey, sleeping in the open air, no matter what the weather. He seems to think this the only way in which it is possible to induce the consumptive to sleep in the fresh air. Doctor Jackson gives the case of a consumptive young man (he does not state the condition of his lungs) who was cured by sleeping in the open air on a hay-stack. This advice and experience do not quite harmonize with the common terror of night air. But while I believe that breathing the pure out-door air all night is an important curative means in this disease, I do not believe that sleeping in the open fields of a stormy night is the _best means_ for securing pure night air, in the case of a feeble woman; on the contrary, I think it might be more pleasantly, and quite as effectually, secured in a comfortable house, with open windows and an open fire.
