"THE SQUARING OF THE CIRCLE."
Liverpool, 9th October 1855. Sin—I do not know whether I am in place in asking for a nook in your valuable journal for the squaring of the circle. I conceive it to be simply this. If you take a silver wire twelve inches and a quarter long, the quar- ter being allowed to unite the two ends, you have a circular wire exactly twelve inches ; and if this wire is made to form the true square, each of its sides will be equal to three inches, and the area equal to nine square inches. Now, if the same wire is allowed to assume the true circle, it is evident that the area of the circle will be the same as it was in the square. For instance, if a wall be built around a city and it is found to be twelve miles round, the area of that city is nine square miles. Therefore, the square of any circle is equal to three-fourths of the length of its own circumference. R D. S.
