to revise and elaborate phonological reconstructions that had earlier been published by
Otto Dempwolff (1934–38). A series of articles such as "The Malayo-Polynesian word for ‘two’" (1947), "The Tagalog reflexes of Malayo-Polynesian D" (1947), "Proto-Malayo-Polynesian *Z" (1951), and "Dempwolff’s *R" (1953), eventually culminated in a monograph, ''The Proto-Malayo-Polynesian laryngeals'' (1953). His application of the same methods to his own new data from Chuukese led to a monograph ''On the history of the Trukese vowels'' (1949), which brilliantly demonstrated how the nine vowels of Chuukese had derived quite regularly from the four-vowel system Dempwolff had reconstructed for Proto-Austronesian.
