 1750 Noro Genjyo visited tlie captain's hotel every year and made 

 inquiries upon the medicinal virtues of the plants mentioned in Dodo- 

 neus's book, and those diah)gues are all on record and preserved. Aoki 

 Konyo also visited the hotel every year and studied the Dutch language, 

 but as the stay of the captain in Yedo was very short Aoki could not 

 get hold of much, so he went to Nagasaki in 1744 in order to acquire 

 better knowledge of the language. He liecame the pioneer of the study

In 1775, Carl Peter Thunberg came to Nagasaki and in the 

 following year to Yedo. Katsuragavva Hoshti and Nakagawa Junnan 

 visited the hotel of the Dutch captain and met Thunberg. These 

 two Japanese physicians spoke the Dutch language pretty well and

 Krtiid BoeJi, and picked out 670 species which can be identified with, 

 or are similar to, Japanese species and made a list of them. In 1827, 

 Udagawa Yoan and Udagawa Shinsai published a revised edition of
