Again, I think that few things press so heavily on one suffering from long and incurable illness, as the necessity of recording in words from time to time, for the information of the nurse, who will not otherwise see, that he cannot do this or that, which he could do a month or a year ago. What is a nurse there for if she cannot observe these things for herself? Yet I have known--and known too among those--and _chiefly_ among those--whom money and position put in possession of everything which money and position could give--I have known, I say, more accidents (fatal, slowly or rapidly) arising from this want of observation among nurses than from almost anything else. Because a patient could get out of a warm-bath alone a month ago--because a patient could walk as far as his bell a week ago, the nurse concludes that he can do so now. She has never observed the change; and the patient is lost from being left in a helpless state of exhaustion, till some one accidentally comes in. And this not from any unexpected apoplectic, paralytic, or fainting fit (though even these could be expected far more, at least, than they are now, if we did but _observe_). No, from the unexpected, or to be expected, inevitable, visible, calculable, uninterrupted increase of weakness, which none need fail to observe. [Sidenote: Accidents arising from the nurse's want of observation.] Again, a patient not usually confined to bed, is compelled by an attack of diarrhoea, vomiting, or other accident, to keep his bed for a few days; he gets up for the first time, and the nurse lets him go into another room, without coming in, a few minutes afterwards, to look after him. It never occurs to her that he is quite certain to be faint, or cold, or to want something. She says, as her excuse, Oh, he does not like to be fidgetted after. Yes, he said so some weeks ago; but he never said he did not like to be "fidgetted after," when he is in the state he is in now; and if he did, you ought to make some excuse to go in to him. More patients have been lost in this way than is at all generally known, viz., from relapses brought on by being left for an hour or two faint, or cold, or hungry, after getting up for the first time. [Sidenote: Is the faculty of observing on the decline?] Yet it appears that scarcely any improvement in the faculty of observing is being made. Vast has been the increase of knowledge in pathology-- that science which teaches us the final change produced by disease on the human frame--scarce any in the art of observing the signs of the change while in progress. Or, rather, is it not to be feared that observation, as an essential part of medicine, has been declining?
