(1) _Sendjirli._--From 1888 to 1891 a German expedition excavated at Sendjirli, near the head-waters of the Kara Su in northern Syria, and brought to light most interesting remains of a civilization that was fundamentally Hittite. Inscriptions found here dated in the reigns of Tiglath-pileser IV and Esarhaddon were in Aramaic. By this time there had been an influx of Aramæans, but the art shows that Hittites held the place at an earlier time, and there is reason to believe that one of the kings mentioned here had, about 850 B. C., joined in a Hittite federation. (2) _Boghaz Koi._--Among the monuments known to Prof. Sayce at the beginning of his brilliant studies of the Hittites, were some from Boghaz Koi, in Asia Minor. Different travelers had noted that here must have been a somewhat extensive city, adorned with several large buildings, all of which were ornamented with carvings of the peculiar Hittite type. In 1906 the late Prof. Winckler, of Berlin, excavating here in connection with the authorities of the Turkish Museum at Constantinople, discovered an archive of clay tablets inscribed in Babylonian characters. A group of similar tablets from Cappadocia had been previously purchased by the British Museum. Winckler’s discovery was important because he found some of the tablets inscribed in Hittite written in cuneiform characters. Of those written in the Babylonian language, one contained a copy of the great treaty between Hattusil, a Hittite king, and Ramses II of Egypt. There were also tablets containing Sumerian and Semitic equivalents of Hittite words. Owing to the long illness of Winckler which followed these discoveries, an illness that terminated in death, the results of this discovery are only now being given to the world. In 1907 Winckler and Puchstein, in conjunction with Makridy Bey of the Turkish Museum, made a thorough examination of the remains of walls and buildings at Boghaz Koi. The results have since been published in a handsome volume entitled _Boghaskoi, die Bauwerke_, Leipzig, 1912; (see Figs. 23 and 25). (3) _Other Recent Excavations._--An American expedition consisting of Drs. Olmstead, Charles, and Wrench, of Cornell University, explored in Asia Minor in 1907-1908. The members of this expedition collated all the known monuments of the Hittites, but so far only their collation of the inscriptions has been published. The Institute of Archæology of the University of Liverpool has also sent one or more expeditions to explore the Hittite country. In 1910 they excavated to some extent at Sakje-Geuze, not far from Sendjirli, but their results are not yet published.
