One of Cayley's last papers, published in 1894, dealt with the quintic: Arthur Cayley, on the sextic resolvent equations of Jacobi and Kronecker, Journal èfèür die Reine und Angewandte Mathematik, CXIII (1894), 42-49. Moreover, he was preparing a paper, entitled A Report on the Quintic, which was incomplete at the time of his death. This manuscript consists of several drafts of this paper. In one of these drafts, he refers to the paper: On the Sextic Resolvent Equations.
