“The Art of Fiction.” Pall Mall Gazette. 30 April 1884. [Vol. 39, No. 5973], 1–2. [Lang reviewed Walter Besant’s lecture, “The Art of Fiction.”]
B. Meredith Langstaff also lists two articles from 1882.
Lang also wrote letters to the editor over the Rider Haggard plagiarism controversy in 1887.
As the Pall Mall Gazette is digitized in British Newspaper Archive, I anticipate that other Lang contributions will be uncovered.
