The totality of straight lines that intersect a conic in three-space generates a very special sort of quadratic complex. The coeffi-cients determining the equation of this complex, when a straight line has the usual Plucker line coordinates, may be taken as the coordinates of the conic, a clumsy enough system. signs of fever
