Casey, in an extensive and complete mémoire, has discussed very thoroughly the bicircular quartic. Among the unfinished notes of Dr Clifford the properties of the curve are established by means of a tetracyclic system of coordinates. Such a system of coordinates has been extensively used by Coolidge. The object this paper is to present a valid discussion of the curve in terms a tricyclic system of “power” coordinates.
