It is necessary to lecture on the history of science for undergraduates of Teacher's College, since the history of science seems to play an important role in school science. From this point of view, author has in views that undergraduates understand the development of scientific thinking in scientists through learning the history of science. " A Travel Discription " of Masumi Sugae (1754~1829) and "Reise nach dem Hofe des Sjogun im Jahre 1826 " of F. F. Siebold are chosen for teaching materials. In the class work present author compared both literatures with each other and undergraduates obtain the following results ; Sugae and Siebold paied their attentions to same natural phenomena and described observation data with same consciousness. Up to date Sugae has not been acknowledged as a scientist in the field of science history, and Siebold greatly appreciated as a contributor to the development of mordern science in Japan. In the field of history of science, studies on the man and work done by Sugae, native scientist, is dispensable. Undergraduates may learn the development of scientific thinking through the recognition and the evaluation of the works not only by famous and acknowledged scientists but by ignored scientists.
