This envelope contained the historical materials produced during the period from the summer to autumn of 1937. These materials give a glimpse into the process of observing cosmic rays and nuclear force, the process of examining the results of analysis and the process of writing the paper, “On the Interaction of Elementary Particles II.” The envelope also included notes and postcards sent by Yukawa’s co-researchers such as Shoichi Sakata and Mitsuo Taketani.
