The two principal views are representedin figs. 5 and 6. 16. The mathematical problem of calculating the forms ofthe plane arc-edges, and of ihe curved surface of the hexa-gonal faces, is easily carried out to any degree of approxima-tion that may be desired ; though it would be very laborious,and not worth the trouble, to do so further than a first ap-proximation, as given in § 17 below. But first let us statethe rigorous mathematical problem ; which by symmetrybecomes narrowed to the consideration of a 60° sector BOBof our non-plane hexagon, bounded by straight lines C
