In 1834 he became a fellow of Trinity, in 1853 professor of Greek (to which a canonry in Ely Cathedral was then for the first time attached), and in 1866 master of his college.
At Rome too he obtained a canonry attached to Cracow cathedral, and on his return to Poland in 1755 threw himself heart and soul into the question of educational reform.
In 1891 he was elected Master of Pembroke College, which dignity carried with it a canonry of Gloucester Cathedral.
On the completion of his studies in law at Padua and in divinity at Louvain, Antoine held a canonry at Besancon, but he was promoted to the bishopric of Arras when barely twenty-three (1J40).
He was a select preacher at Oxford in 1895-1897, and at Cambridge in 1900; he received a canonry in Bristol cathedral in 1893, but retained his wardenship of Toynbee Hall, while relinquishing the living of St Jude's.
