Newton's keepership at the museum was marked by an amassing wealth of important acquisitions, which were largely attributable to his personal influence or initiation. Thus in the ten years 1864-74 alone he was enabled to purchase no less than five important collections of classical antiquities: the Farnese, the two great series of Castellani, the Pourtales, and the Blacas collections, representing in special grants upwards of £100,000. Meanwhile, his work in the Levant, bringing to the museum the direct results of exploration and research, was being continued by his successors and friends: Biliotti in Rhodes, Smith and Porcher at Gyrene, Lang in Cyprus, Dennis in Sicily, in the Cyrenaica, and around Smyrna, Pullan at Priene, John Turtle Wood at Ephesus were all working more or less directly under Newton on behalf of the museum.
