In conclusion, the pleasant task remains to me of expressing my 

 obligations, and offering my thanks to Hiroyuki Kato, Esq., President 

 of the University of Tokio, who has rendered my task a comparatively 

 easy one, by the assistance he has given me in various ways. To 

 Mr. Jihei Kameyama also, the proprietor of the koji manufactory in 

 Yushima, Tokio, I am deeply indebted for the willingness with which 

 I have been allowed to make experiments, and to collect information 

 in his works. I wish also to thank my assistant, Mr. ISTakazawa, for 

 the interest he has taken in the research, and for much assistance 

 which I have received from him.
