DR. SCHLIEMANN has been in London for a week or two. He has in preparation a book on his discoveries at Tiryns. The _Academy_ communicates the following details with regard to these discoveries: “The walls of the prehistoric palace which Dr. Schliemann has disinterred at Tiryns are formed of limestone and clay; the latter has been turned into brick by the action of fire, while the stone has been burnt into lime. In some places the surface of the walls had been coated with stucco, on which traces of painting can still be observed. The colours used in these paintings are black, red, blue, yellow, and white; and Professor Virchow has pointed out that the blue is composed of pulverised glass mixed with copper, but without cobalt. One of the paintings represents the same pattern as that found on the roof of the thalamos attached to the Treasury of Minyas at Orchomenos. Another depicts a man riding on an ox, whose tail he holds. The artist has made three attempts to draw the tail, and has forgotten to obliterate the two unsuccessful ones. The paintings have been carefully removed and sent to Athens. Among the ruins of the palace twenty-seven bases of limestone columns have been discovered, but no drums, besides a sandstone capital in the old Doric style. The chambers of the building were full of objects of all kinds, including pottery, obsidian knives, rude hammers of diorite, and grape-stones. No iron has been met with, and but little metal of any sort, though lead is relatively plentiful. All traces of writing are equally absent. The pottery resembles that of Mycenæ, but the presence of obsidian and the scarcity of metal imply that Tiryns was the older city of the two.”
