Two newspaper articles published in 1949 and a booklet entitled "Der Bamburger Reiter: deutsches Symbol," both by Rost. Also included are two letters received by Rost and two sections of rough drafts of articles or essays. Dr. Rost wrote in defense of the Catholic Church in the political climate of Germany.

This collection consists of a set of lecture notes taken from the addresses of Wilhelm Max Wundt (1832-1920) from 1898-1899 while Rost was a student at Leipzig. They deal with the topics of philosophy, logic, and psychology. These notes appear to be paraphrases of Wundt's lectures. Wundt published numerous works on each of these topics.

Handwritten essay and correspondence in German. The essay deals with primitive tribes. One of the letters is to Rost from his publisher. The other is from Rost and expresses interest in biblical studies.
