One day a laboring man came to me with indigestion. He had a sour and sore stomach, and heartburn, and the water-brash, and wind, and colic, and wonderful misery of body and mind. I found he was eating bad food, and too much of it; and then, when its digestion gave him pain, he took a glass of raw whiskey. I made him promise to give up his bad food and his worse whiskey, and live on pease-brose and sweet milk, and I wrote him a prescription, as we call it, for some medicine, and said, "Take _that_, and come back in a fortnight and you will be well." He did come back, hearty and hale;--no colic, no sinking at the heart, a clean tongue, and a cool hand, and a firm step, and a clear eye, and a happy face. I was very proud of the wonders my prescription had done; and having forgotten what it was, I said, "Let me see what I gave you." "O," says he, "I took it." "Yes," said I, "but the prescription." "_I took it_, as you bade me. I swallowed it." He had actually eaten the bit of paper, and been all that the better of it; but it would have done him little, at least less good had he not trusted me when I said he would be better, and attended to my rules. So, take my word for it, and trust your Doctor; it is his due, and it is for your own advantage. Now, our next duty is to _obey_ the Doctor. This you will think is simple enough. What use is there in calling him in, if we don't do what he bids us? and yet nothing is more common--partly from laziness and sheer stupidity, partly from conceit and suspiciousness, and partly, in the case of children, from false kindness and indulgence--than to disobey the Doctor's orders. Many a child have I seen die from nothing but the mother's not liking to make her swallow a powder, or put on a blister; and let me say, by the by, teach your children at once to obey you, and take the medicine. Many a life is lost from this, and remember you may make even Willie Winkie take his castor-oil in spite of his cries and teeth, _by holding his nose_, so that he must swallow. _Thirdly, You should tell the truth, the whole truth, and nothing but the truth_, to your Doctor. He may be never so clever, and never so anxious, but he can no more know how to treat a case of illness without knowing all about it, than a miller can make meal without corn; and many a life have I seen lost from the patient or his friends concealing something that was true, or telling something that was false. The silliness of this is only equal to its sinfulness and its peril.
