Note 6 — I. Introductory.

The four Codices can be obtained by placing an order with one of the leading importers of foreign books in New York City. The four cost about one hundred dollars. The study of the German writers is indispensable. The contributions of Dr. Schellhas and Dr. Seler will be found in the numbers of the Berlin Zeitschrift für Ethnologie, 1886 and later. Dr. Förstemann has likewise published in the Zeitschrift, 1891, and also in the Centralblatt für Bibliothekwesen, in which remote quarter some of his most thoughtful contributions have appeared; and in the Proceedings of the International Congress of Americanists. Four of his articles bear the general title, “Zur Entzifferung der Mayahandschriften,” I, II, III, IV. I refer to them by these numbers. The articles of Professor Thomas, Professor Rau, and Mr. Holden are contained in the annual reports of the Bureau of Ethnology, Washington, where they can be readily consulted by American students.
