“Without disparaging the services which many physicians have rendered to the sciences auxiliary to medicine, to natural philosophy and chemistry, to natural history in its various branches, and to that of man in particular, to anthropology, physiology and anatomy, etc., I shall occupy myself here with the practical part of medicine only, with the healing art itself, in order to show how it is that diseases have hitherto been so imperfectly treated. Far beneath my notice is that mechanical routine of treating precious human life according to the prescription manuals, the continual publication of which shows, alas! how frequently they are still used. I pass it by unnoticed, as a despicable practice of the lowest class of ordinary practitioners. I speak merely of the medical art as hitherto practiced, which, pluming itself on its antiquity, imagines itself to possess a scientific character.”
