Letter to the Congregation of Propaganda Fide (7 November 1892)
Your Eminence,
The extensive mission of Upper Congo, situated within the territory of the independent State and serve by the priests of the Society of Missionaries of Algiers, is at the moment without a leader. Reverend Father Coulbois who had been in charge of the administration this last period, with the function of ProVicar Apostolic, returned to Europe in April of the present year for serious health reasons and finds himself obliged, for the same reasons, to resign definitively from his previous office.
