Having refused to accept the civil constitution of the clergy, Dillon had to leave Narbonne in 1790, then to emigrate to Coblenz in 1791.
Captain Peter Dillon at length ascertained, in 1828, that the ships of La Perouse had been wrecked on the island of Vanikoro during a hurricane.
Edward Dillon (Glass, 1902) has very properly laid stress on the importance of the enamelled Saracenic glass of the r3th, 14th and r 5th centuries, pointing out that, whereas the Romans and Byzantine Greeks made some crude and ineffectual experiments in enamelling, it was under Saracenic influence that the processes of enamelling and gilding on glass vessels were perfected.
Dillon has pointed out that the process of enamelling had probably been derived from Syria, with which country Venice had considerable commercial intercourse.
Hartshorne and Dillon have drawn attention to the important part played by the little Ligurian town, Altare, as a centre from which glass-workers migrated to all parts of Europe.
