P. 72, line 3: For "Dampier" read "Cowley?" (See also our VOL. XXXIX, p. 115, note.) Note 11: In the Philippine Journal of Science (published by the Bureau of Science, Manila), for October, 1906, is an interesting paper on "The Non-Christian Tribes of Northern Luzon," by Dean C. Worcester, secretary of the interior in the government of the islands. He endeavors to furnish a systematic classification of these tribes; repeats the lists made by the Jesuits, Professor Blumentritt, and Dr. Barrows, criticizing each of these, and in some respects differing from their methods; and then enumerates the separate tribes, as classified by himself--giving under each, the synonyms of the tribal name, with other names which may be classed under this; "its habitat, so far as it is at present known;" and description of its people, and of their dress, homes, mode of life, occupations, customs, etc. A similar paper on those tribes in Southern Luzon is announced for the coming year. For these papers Worcester has utilized personal observations made on these peoples not only by himself, but by numerous other government officials both civil and military, during the years 1900-06; and special information regarding them obtained in the census enumeration of 1903. He says (p. 802): "It is not too much to say that hardly a rancheria now remains in the Cordillera Central and its foothills, except in the district of Apayos, which has not been visited by Americans, while even in the latter district twenty-nine of the more important rancherias have been visited." The above paper contains excellent illustrations made from 208 photographs, taken by Worcester himself or other government officials. Other valuable papers announced for the Journal in 1907 are: "The Tagbanua and Mangyan Alphabets," by T. H. Pardo de Tavera; "The Subanos of the Zamboangan Peninsula," by Edwin B. Christie; and "Primitive Philippine Fire-making Apparatus," by Dean C. Worcester. P. 78, note 13: Worcester recognizes but seven distinct non-Christian tribes in northern Luzon: the Negritos, Ilongots (Ibilaos), Kalingas, Ifugaos, Bontoc Igorots, Lepanto-Benguet Igorots, and Tinguians. He says of some of these tribal designations ("Non-Christian Tribes of N. Luzon," p. 804): "The Altasanes, Ifumangies [the same as Jumangi], Ileabanes, and Panuipuyes do not exist. In all probability these latter names were taken from those of rancherias which have long since disappeared. While some of the larger rancherias in northern Luzon are very old, others are of recent origin and the names and locations of these settlements are constantly changing."
