The fonds consists of three scrapbooks, and textual records that include obituaries and letters written in memory of C. P. Martin by McGill faculty and former students, index cards of C. P. Martin's religious reflections on the bible, typed and handwritten sermons, C. P. Martin's nature journal, a copy of Francis Shepherd Memorial Lectures 1953-1956, and some letter correspondence. Two of the scrapbooks document C. P. Martin's personal family life (including family trees depicting five generations, his leisurely interests etc.) and his professional life at McGill, with many newspaper clippings about McGill University and faculty. The other scrapbook contains mostly British Medical Journal clippings (1942-1954).
