e parallels are, and the quadrilateral figure KBOS V->vJ is in one plane: and if PB, TK be joined, and perpendicularsbe drawn from the points P, T to the straight lines AB, AK,it may be demonstrated, that TP is parallel to KB in the verysame way that SO was shown to be parallel to the same KB; a… … Therefore, if from the points O, S, P, T, R, Y there be drawnstraight lines to the point A, there shall be formed a solid po-lyhedron between the circumferences BX, KX composed o£pyramids, the bases of which are the quadrilaterals KBOS,SOPT, TPRY, and the triangle YRX, and of which the com-mon…
