In the summer of 1938, at the Linguistic Institute in Ann Arbor, Sturtevant gave a public lecture on his Indo-Hittite hypothesis, which was then very much in the foreground of discussion. The next year, C. C. Fries, as Director of the Institute, persuaded Sturtevant to allow the lecture to be printed in the announcement and course program for the Institute of 1939, as the first (and, as it turned out, the last) of what Fries hoped might be a regular feature of such programs.
The lecture, in its published form, had a limited circulation. At the time and for a little while thereafter, Fries received a number of requests for copies. But the publication remained largely unknown, and in particular seems never to have reached European scholars. For this reason, Fries has now suggested that the lecture be reprinted in Language, so that it may at last enjoy the wider circulation which it deserves as the most concise defense of his hypothesis that Sturtevant ever put together.
The article is reprinted here verbatim from the course program of the 1939 Linguistic Institute, except that the bibliographical references in the footnotes have been changed to the form customary in Language.—The Editor.
