How much my little patient was injured, permanently, by this act of unpardonable carelessness, I never knew. It may have laid the foundation for many ills which he has since experienced, some of which have been severe and trying. Or, if otherwise, it may have aggravated such ills as had their origin in other causes. Or, if nothing more, it may have contributed to a delicacy and sensitiveness and feebleness of structure, which can never, in all probability, be fully overcome, and which have more to do, even with our moral tendencies and character, than most of us are fully aware. How much would I give to be able to blot from my history such errors and defects of character as this! For, though I confess to nothing worse than haste and carelessness, in the present instance, yet a medical man, like the commander in the battle field or elsewhere, has no right to be careless. My aged, honored father gravely insisted, all his life long, that no accidents, as they are termed, in human life, ever take place, unless there is in the first place, carelessness, somewhere. Much more is it true that many an individual who sickens and loses his life, is the victim of carelessness; or, what is the same thing, want of attention, when great care and attention were necessary, and the issues of life and death were suspended, as it were, on a thread! CHAPTER LX. MRS. KIDDER'S CORDIAL. Should you ever go to Boston, and pass along a certain street called Court Street, almost to its western extremity, you may probably see at your left hand, in large letters of various fantastical shapes, the words which I have placed at the head of this chapter; viz., "MRS. KIDDER'S CORDIAL." Sometimes, I believe, it is called her cholera cordial; but it is sufficiently well known, as I suppose, by the former name. But how is it known? Not merely by the sign I have mentioned, fastened up at the door of that aforesaid shop in Court Street, but by a host of advertisements in the public papers; and in other cities as well as Boston. You may find them in almost every public house, post-office, railroad depot, and grocery in New England; or, as I might perhaps say, in the whole Union. I once had a child severely sick, at a season of the year when not only the Asiatic cholera prevailed, but also the cholera morbus. She was teething at the time, which was doubtless one cause of her illness,--to which however, as I suppose, other causes may have been added. In any event, she was in a very bad condition, and required the wisest and most careful medical attention. There was also a young woman in the house who was ill in the same way, but not so ill as the child.
