Meanwhile, he had won the Degree of Doctor of Letters with a Latin and a French thesis, the latter being honoured with a prize from the Académie française for two years.
He succeeded Charles Émile Freppel, one of the most remarkable bishops of his time, and set himself to maintain all his predecessor's good works.
He inaugurated the same enterprise in the Diocese of Toulouse, to which he was transferred three years later (30 May 1896) by a formal order of Pope Leo XIII.
With this aim he wrote the Devoir des catholiques, an episcopal charge which attracted wide attention and earned for him the pope's congratulations.
Having resigned the See of Toulouse (14 December 1899), his activities were thenceforward absorbed in the work of the Roman congregations and some secret diplomatic negotiations.
