The best remedy for a _hard corn_ is to remove it. The usual method of cutting, or of paring a corn away, is erroneous. The following is the right way; Cut with a _sharp_ pair of pointed scissors around the circumference of the corn. Work gradually round and round and toward the center. When you have for some considerable distance well loosened the edges, you can either with your finger or with a pair of forceps generally remove the corn bodily, and that with little pain and without the loss of any blood. If the corn be properly and wholly removed, it will leave a small cavity or round hole in the center, where the blood-vessels and the nerve of the corn—vulgarly called the root—really were, and which, in point of fact, constituted the very existence or the essence of the corn. Moreover, if the corn be entirely removed, you will, without giving yourself the slightest pain, be able to squeeze the part affected between your finger and thumb. _Hard corns_ on the sole of the foot and on the sides of the foot are best treated by filing—by filing them with a sharp cutting file (flat on one side and convex on the other), neither too coarse nor too fine in the cutting. The corn ought, once every day, to be filed, and should daily be continued until you experience a slight pain, which tells you that the end of the corn is approaching. Many cases of _hard corn_, that have resisted every other plan of treatment, have been _entirely_ cured by means of the file. One great advantage of the file is, it cannot possibly do any harm, and may be used by a timid person, by one who would not readily submit to any cutting instrument being applied to the corn. The file, if properly used, is an effectual remedy for a _hard corn_ on the sole of the foot. I myself have seen the value of it in several cases, particularly in one case, that of an old gentleman of ninety-five, who had a corn on the sole of his foot for upwards of half a century, and which had resisted numerous, indeed, almost innumerable, remedies; at length I recommended the file, and after a few applications entire relief was obtained, and the corn was completely eradicated. The corns between the toes are called _soft corns_. A _soft corn_ is quickly removed by the strong acetic acid—acid. acetic. fort.—which ought to be applied to the corn every night by means of a camel’s-hair brush. The toes should be kept asunder for a few minutes, in order that the acid may soak in; then apply between the toes a small piece of cotton-wool. _Hard corns_, then, on the sole and on the side of the foot, are best treated by the file; _hard corns_ on the toes by the scissors; and _soft corns_ between the toes by the strong acetic acid.
