But what surprised me more than I can well express was that a candle burned in this air with a remarkably vigorous flame...
Stran 786 - The rectangle contained by the diagonals of a quadrilateral ,figure inscribed in a circle, is equal to both the rectangles contained by i'ts opposite sides.

Stran 673 - The area of the inscribed regular hexagon is the mean proportional between the areas of the inscribed and circumscribed equilateral triangles.
Stran 378 - Law, Medicine, Education, and Divinity. Instruction is given by regular members of the University staff which is augmented in the summer by appointment of professors and instructors from other institutions.
