A geometric condition of such figure is that the sums of the logarithmic sines of the angles about the base, taken in one direction, must equal the similar sums taken in the other direction, ie the product of the sines must be equal. In the present case,... Report - Seite 295von Maryland Geological Survey - 1898Vollansicht - Über dieses Buch
