Clearly, any line, l, of any bundle having one of these points of tangency, T, as vertex will be transformed into the entire pencil having the image of the second intersection of L and Q as vertex and lying in the plane determined by the image point and the generator of Af which is tangent to **zg at T.

the second requires that there be a line through P which meets **zg in Af points.

In the second, the fixed elements are the lines which join the vertex, P, to the two intersections of **zg and the plane of the pencil which do not lie on the multiple secant.

Continuing with the case in which **zg is a Af curve on a quadric Q, we first observe that the second regulus of Q consists precisely of the lines which join the two free intersections of **zg and the planes through any one of the multiple secants.
