I should describe mine own nature as tripartite, my interests consisting of three parallel and dissociated groups—(a) Love of the strange and fantastic. (b) Love of the abstract truth and of scientific logick. (c) Love of the ancient and the permanent. Sundry combinations of these three strains will probably account for all my odd tastes and eccentricities.
