This paper serves as a topical outline arranged in chronological order of the circular letters of the superior general of the Congregation of the Mission, 1878-1914, Antoine Fiat. It will allow researchers to follow Fiat's development during his generalate, the longest in the history of the Vincentians. The circular letters were published individually in French, and are found in appropriate archives. The pagination of the original has been maintained where possible. Unpublished circulars follow the appropriate published circulars, with an added letter (e.g., #3a).
