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?
Which of us has not heard fifty times, from one or another, a nurse, or a friend of the sick, aye, and a medical friend too, the following remark:—“So A is worse, or B is dead. I saw him the day before; I thought him so much better; there certainly was no appearance from which one could have expected so sudden (?) a change.” I have never heard any one say, though one would think it the more natural thing, “There must have been some appearance, which I should have seen if I had but looked; let me try and remember what there was, that I may observe another time.” No, this is not what people say. They boldly assert that there was nothing to observe, not that their observation was at fault.
Let people who have to observe sickness and death look back and try to register in their observation the appearances which have preceded relapse, attack, or death, and not assert that there were none, or that there were not the right ones.*
