From universal remedies or panaceas, to nostrums and specifics, such, for instance, as pretend to cure the _same_ disease in every patient, is easy and natural. With the latter also, impositions of a dangerous tendency are often practised. It may be asked how far they are practicably admissible, and in what cases they are wholly unavailing? The answer is not difficult. In those diseases, which in every instance depend upon the same cause, as in agues, the small-pox, measles, and many other contagious distempers, the possibility of specifics, in a limited sense, may be rationally, though hypothetically admitted. But in either maladies, the causes of which depend on a variety of other concurrent circumstances, and the cure of which in different individuals, frequently requires very opposite remedies, as in dropsy, various species of colds, the almost infinite variety of consumptions, etc. a specific remedy is an imposition upon the common sense of mankind. Those who are but imperfectly acquainted with the various causes from which the same disorder originates in different individuals, can never entertain such a vulgar and dangerous notion. They will easily perceive, how much depends upon ascertaining with precision, the seat and cause of the complaint, before any medicine can be presented with safety or advantage:--even life and death are, we are sorry to add, too often decided by the first steps. Different constitutions, different symptoms, and stages of disease, all require more or less a separate consideration. What is more natural than to place confidence in a remedy, which has been known to afford relief to others in the same kind of disposition? The patient anxiously enquires after a person who has been afflicted with the same malady; he is eager to know the remedy that has been used with success; his friend or neighbour imparts to him the wished for intelligence; he is determined to give the medicine a fair trial, and takes it with confidence. From what has been stated, it will not be difficult to conceive, that if his case does not exactly correspond with that of his friend, any _chance_ remedy may prove extremely dangerous, if not fatal. Hence it becomes evident, that the results are not to be depended upon, nor the chance risked. The physician is obliged to employ all his sagacity, supported by his own experience, as well as by that of his predecessors; and yet he is often under the necessity of discovering, from the progress of the disease, what he could not derive from the minutest research. How then can it be expected, that a novice in the art of healing should be more successful, when the whole of his method of cure is either the impulse of the moment, or the effect of his own credulity? It may be therefore truly said, that life and death are frequently entrusted to chance!
