Thesis (M.A.)--Univ. of California. Dec. 1916,

Two geometrical memoirs on the general properties of cones of the second degree, and on the spherical conics,

Available on demand as hard copy or computer file from Cornell University Library.

Researches on curves of the second order, also on cones and spherical conics treated analytically, in which the tangencies of Apollonius are investigated, and general geometrical constructions deduced from analysis; also several of the geometrical conclusions of M. Charles are analytically resolved, together with many properties entirely original.
