A revised edition of Joh. Warneck's
Toba-Bataksch–Deutsches Wörterbuch
(Landsdrukkerij, Batavia, 1906). The additions and corrections in this edition are by the late J. Winkler, who, like the author, worked in Sumatra for the Rheinischen Missionsgesellschaft. It also includes a 42 page register Deutsch–Batak, compiled by K.A. Adelaar, aimed to facilitate the use of the dictionary for linguistic purposes.
