"Construction einer Ellipse, aus Luqsor," pp. 7576 + plate; an ellipse, with lines for its construction, in the east wall of the Temple of Luxor. Borchardt compares the analysis of this construction with apparently similar reasoning for the quadrature of the circle in the Rhind papyrus (no. 48).

Numerous references to Eisenlohr (1877); he insists (pages 42-43) on his interpretation of the seked of a pyramid—rejected by other scholars.

Bobynin here refers to what is usually known in mathematical literature as the "Russian peasant method of multiplication." For various references in this connection see R. C. Archibald, "The binary scale of notation, a Russian method of multiplication, the game of nim, and Cardan’s rings," American Mathematical Monthly, vol. 25, 1918, pp. 139—142.

An attempt to explain, by means of a hemisphere, problem (c) below, Griffith (1897). Schack-Schackenburg (1899) showed that the solid in question was probably a right circular cylinder, and this interpretation has been accepted by Peet (1923. 2) and others.
