P. 27. PALÆOLITHIC IMPLEMENTS. Reports of the discovery of very large numbers of supposed palæolithic implements in various parts of the United States have been collected and published by Mr. Thomas Wilson in the _Report of the U. S. National Museum_, 1887-88, pp. 677-702. These implements, however, are called palæolithic from their form and workmanship only, and not from the stratigraphic relations in which they were found. As palæolithic forms often survived in the riper culture of the neolithic age, the only positive proof of their older origin must be that they are found in undisturbed relation to older strata. P. 33. REMAINS OF MAN IN THE EQUUS BEDS. What American geologists call the Equus Beds are those which yield in abundance the bones of various species of fossil horse, as _E. major_, _occidentalis_, _excelsus_, _barcenæi_, _fraternus_, _crenidens_, etc., most of which have been determined by Dr. Joseph Leidy and Prof. E. D. Cope. The principal localities of these beds are: 1. The Oregon Desert; 2. The country of the Nueces, in southwestern Texas; and 3. The valley of Mexico. The horizon to which these beds should be referred was considered by Prof. King to be the Upper Pliocene; but by Prof. G. K. Gilbert, Dr. Joseph Leidy, and I think, by Prof. Cope, it is rather held to be pleistocene or early quaternary, probably as old as the great glacial phenomena of the Continent. According to Cope and Gilbert, rude stone implements have undoubtedly been found _in place_ in the Equus beds of Nevada, California and Southwestern Texas. See the _American Naturalist_, 1889, p. 165; _Proc. Acad. Nat. Sciences_, Phila., 1883, p. 134, sq. Pp. 106, 108. KWAKIUTL AND NOOTKA STOCKS. After the pages referred to had been printed, I received, through the kindness of Mr. Horatio Hale, advance sheets of the Sixth Annual Report of the Committee of the British Association on the tribes of the Northwest Coast, prepared by Dr. Franz Boas, with an introduction by Mr. Hale, and including eighteen vocabularies. Dr. Boas’ researches furnish clear evidence of a connection between the Kwakiutl and the Nootka tongues, and there is little doubt that they are distantly related. An instructive article on the physical characteristics of the Indians of the North Pacific coast is contributed by Dr. Boas to the _American Anthropologist_ for January, 1891. His conclusion is: “Each tribe appears composed of many types, but in each we find a marked prevalence of a certain type.”
