the help of the venerable Fujibayashi Taisuke he began the 
study of foreign learning. From time to time he botanized 
in the hill-tracts of Hiyei, Kibune, Kurama, and Atago, and 
in the following years in the provinces ofYamashiro, Settsu, 
Yamato, Ise, Shima, Mikawa, Totomi, and Suruga. He was 
then invited to Yedo, and enjoyed the hospitality of the 
venerable Udagawa Yoan 1 , with whom he spent a month 
collecting in Nikko, whence he returned to his native Nagoya 
by Haruna and Myogi in Kozuke, and Kiso in Shinano. 
A little earlier the German botanist Ph. Fr. von Siebold had 
arrived in Japan and taken up his residence at Nagasaki. 
In 1826, desiring to behold the Shogun’s court, he went up to 
Yedo, and on the way, at Atsuta, a coolie-relay station in 
Owari, met Mizutani Sukeroku and Okochi Sonshin, together 
with the venerable subject of this memoir—to the great 
pleasure and profit of all, as one may well believe. The 
meeting is mentioned in Siebold’s Nippon :— c Ich lernte hier 
die meinen Untersuchungen spater so nutzlich gewordenen 
Ito Keiske und Okutsi Sonsin kennen ’ (Siebold : Nippon , 
vol. i, Abteilung I, p. 168). Ito Keisuke could scarcely bear to 
part from Herr von Siebold, and accompanied him as far as 
Narumi. When they separated, von Siebold expressed his 
great desire to see his fellow traveller again at Nagasaki, and 
thenceforth Ito Keisuke could not rest until he had gained 
permission from his father and elder brother to make the 
journey to Nagasaki. It was with no little delight he set 
out on the journey, and in his old age he often recalled the 
pleasure he felt, and frequently spoke to the present writer 
of the delightful anticipations of that time. In 1827, in the 
9th month, being in his 25th year, he arrived at Nagasaki, 
and lodged in the house of the Chief Interpreter Yoshio 
Gonnosuke. He lost no time in calling upon von Siebold, 
who was delighted to see him again. The whole of the time 
1 Udagawa Yoan was a very remarkable man, who took a large part in intro¬ 
ducing western science to his countrymen. He published a work on seimi 
(chemie) in 1837 ( Seimi Keiso ), and earlier still, in 1834, an elementary treatise 
on western botany, Shoku-gaku Keigen.
