It is often said that, in regimental hospitals, patients ought to "nurse each other," because the number of sick altogether being, say, but thirty, and out of these one only perhaps being seriously ill, and the other twenty-nine having little the matter with them, and nothing to do, they should be set to nurse the one; also, that soldiers are so trained to obey, that they will be the most obedient, and therefore the best of nurses, add to which they are always kind to their comrades. Now, have those who say this, considered that, in order to obey, you must know _how_ to obey, and that these soldiers certainly do not know how to obey in nursing. I have seen these "kind" fellows (and how kind they are no one knows so well as myself) move a comrade so that, in one case at least, the man died in the act. I have seen the comrades' "kindness" produce abundance of spirits, to be drunk in secret. Let no one understand by this that female nurses ought to, or could be introduced in regimental hospitals. It would be most undesirable, even were it not impossible. But the head nurseship of a hospital serjeant is the more essential, the more important, the more inexperienced the nurses. Undoubtedly, a London hospital "sister" does sometimes set relays of patients to watch a critical case; but, undoubtedly also, always under her own superintendence; and she is called to whenever there is something to be done, and she knows how to do it. The patients are not left to do it of their own unassisted genius, however "kind" and willing they may be. IV. NOISE. [Sidenote: Unnecessary noise.] Unnecessary noise, or noise that creates an expectation in the mind, is that which hurts a patient. It is rarely the loudness of the noise, the effect upon the organ of the ear itself, which appears to affect the sick. How well a patient will generally bear, _e. g._, the putting up of a scaffolding close to the house, when he cannot bear the talking, still less the whispering, especially if it be of a familiar voice, outside his door. There are certain patients, no doubt, especially where there is slight concussion or other disturbance of the brain, who are affected by mere noise. But intermittent noise, or sudden and sharp noise, in these as in all other cases, affects far more than continuous noise--noise with jar far more than noise without. Of one thing you may be certain, that anything which wakes a patient suddenly out of his sleep will invariably put him into a state of greater excitement, do him more serious, aye, and lasting mischief, than any continuous noise, however loud. [Sidenote: Never let a patient be waked out of his first sleep.]
