A note on some new Properties of Surfaces of the second 

 Order, by John H. Jellett, Esq., F.T.C.D., was read. 



I. Let the points on the focal conic, at which the tangent 

 is parallel to the trace of the tangent plane, be considered 

 analogous to foci. 



II. Let the axis of the surface, perpendicular to the plane 

 of the conic, be considered analogous to the conjugate axis ; 

 then, since the square of the distance from focus to centre, in 

 a conic, is equal to the difference between the squares of the 

 transverse and conjugate serai-axis, we may consider, as ana- 

 logous to the transverse semi-axis, the line drawn to the ex-
