A Short Memoir of Ito Keisuk6, Rigaku 
Hakushi (Doctor of Philosophy) \ 
BY 
TOKUTARO ITO, D.Sc. 
With a Portrait (Plate XXII). 
HE following translation of M. Tokutaro Ito’s valuable 
X memoir of his celebrated grandfather is for the most 
part a full one, but occasionally omission and compression 
have been exercised. It is hoped that it will be found 
interesting, as the memoir of a Japanese botanist of Old as 
well as of New Japan, who was also one of the principal 
pioneers of western science in Japan, written by a Japanese 
for Japanese readers. 
M. Tokutaro Ito’s memoir was originally published in' the 
Toyo Gakugei Zasshi (Journal of Oriental Science and Art) 
in 1898. 
I have to thank my friend Mr. Kumagusu Minakata for help 
in reading some of the proper names and in other ways. 
The rendering of Japanese titles, many of which are new 
since I left Japan twenty years ago, has given me considerable 
trouble, and I am not sure that I have always hit upon the 
exact English equivalents—perhaps because they do not exist.

1 The editors are much indebted to Mr. F. Victor Dickins for translating the 
original Japanese memoir, and to Dr. Tokutaro Ito for readily consenting to its 
publication.
