A privately printed edition of the author's doctoral thesis at UNAM, on an apparently novel method for spherical perspective drawing, "Aplicable en las Artes Plásticas, Arquitectura, Ingeniería Civil, Militar y Aérea, Geometría y Trigonometría Esférica." The thesis follows on and synthesizes previous work by the author, who was a painter and teacher, on the same subject. No record appears to exist for the work on OCLC.
