To quickly assess the difficulty of the text, read a short excerpt:
Also (Article 27), there are two corresponding front-normals Ofi, 0/ 2, lying in the planes OrH lt Orl? 2, and perpendicular to OE lt OR& respectively. But we have seen that in the case of a bi-radial Os lt every point S on the conjugate section corresponds to a ray transmissible along that direction with the velocity b. Further, Os l is not an axis of the indicatrix, and thus is only coincident with the corresponding central normal On for the two rays transmissible in the direction Os^ which c...orrespond to the two points B, B t in which the axis BOB meets the conjugate section. ]\r If M"M' (Fig. J. 7) be the right circular cylinder touching the indicatrix in the curve MSM, in which the plane conjugate to the bi-radial 0^ meets the indicatrix, and M'S'M' be a basal section perpendicular to the axis, the front-normal On, corresponding to any point S on the curve, is in the plane 88' s 1 passing through the axis of the cylinder, and is at right angles to OS. Hence, as the point S moves round the curve MB SI, the corresponding normal On describes a cone of which the bi-radial 0^ is an edge, for it corresponds to the points B, ff, on the curve : the cone may be conveniently designated a bi-radial cone.
