A Budget of Paradoxes, Volume II Augustus de Morgan

Book Excerpt: ...to 60, with equal generation in each irreptitious approximation, therefore meeting in 75, and which is the mean angle of the quadrant."Or suppose a line drawn from a given point at 90, and from the same point at 60. Let each of these lines revolve on this point toward each other at an equal ratio. They will become one line at 75, and bisect the curve, which is one-sixth of the entire circle. The result, taking 16 as a diameter, gives an area of 201.072400, and a circumference of 50.2681."The original conception, its natural harmony, and the result, to my own mind is a demonstrative truth, which I presume it right to make known, though perhaps at the hazard of unpleasant if not uncourteous remarks."I have added punctuation: the handwriting and spelling {11} are those of an educated person; the word irreptitious is indubitable. The whole is a natural curiosity. The quadrature and exact area of the circle demonstrated. By Wm. Peters. 8vo. n. d. (circa 1848)....
