In SIAM two changes of policy appear to be impending. The King, who refused to treat with Sir James Brooke, died on the 3d of April, and his throne is now occupied by two of his brothers; the eldest being first, and the other second king. This division of authority is not without precedent in Siam, and has taken place in the present instance in accordance with a legal nomination, made by the late King. There is little doubt but that for the future a different and more enlightened course of policy will be pursued towards foreigners. The new ruler-in-chief is a man of more than usual education, speaking English, and being somewhat acquainted with literature and science, and he has stated that if the English and American ambassadors return, they will be kindly received, and liberal treaties negotiated with them. _Scientific Discoveries and Proceedings of Learned Societies._ At a recent meeting of the _Royal Society of Literature_, Colonel Rawlinson read a most interesting paper, containing the announcement of a discovery of great historical importance. In looking over the large collection of new cuneiform inscriptions recently brought by Mr. Layard from Assyria, he has met with one recording the annals of the "Koyunjik King." Under the head of the third year occurs a notice which determinately proves the king in question to be the biblical Senacherib, and contains some other remarkable verifications of Scripture. The record, after giving an account of the king's war against the king of Sidon, and describing the battle between the Assyrians and Egyptians, in conformity with the statements of Josephus and Herodotus, presents a distinct notice of the proceedings of Senacherib against Hezekiah, king of Judea. The names in the inscription are _Khazakiyah_, _Ursalimma_, _Jehuda_; and the tribute which the Jewish king pays, in order to free himself from his enemy, is stated almost in the very words of Scripture. The annals of Senacherib in this inscription extend over seven years, and a cylinder has been met with which gives the events of two years more. Other points of identity between these annals and the Greek and the biblical notices of Senacherib likewise occur; but the chief point of interest is the establishment of the identity of the king who built the great palace of Koyunjik with that sovereign. A secure starting-place is now obtained for historical research, and it rapid progress will be made in fixing the Assyrian chronology. Colonel Rawlinson's paper was read at one of the four evening meetings which the Society has held this season for the reception of its foreign members and friends. The Earl of Carlisle was in the chair. * * * * *
