The Circle squared; together with the Ellipsis and several reflections
on it. The finding two geometrical mean proportionals, or doubling the
cube geometrically. By Richard Locke[309].... London, no date, probably
about 1730, 8vo.
According to Mr. Locke, the circumference is three diameters, three-fourths
the difference of the diameter and the side of the inscribed equilateral
triangle, and three-fourths the difference between seven-eighths of the
diameter and the side of the same triangle. This gives, he says, 3.18897.
There is an addition to this tract, being an appendix to a book on the
longitude.
