to whom I here publicly tender ray hearty thanks for the courtesy, with which 

 they have met every wish of mine with regard to the execution of the work. 

 For the translation of the original, which, owing to the great number of technical 

 terms, offered especial difficulties, I am indebted to Mr. A, Kosenstand. 



My thanks are further due to Mr. W.Watanabe for his valuable assistance 

 in various directions. 



As in Vol. I of the Memoirs, so also in this volume, is the entire mechanical 

 part of the pamphlet — drawings, lithographs, printing and paper — of Japanese 

 origin, and I wish to record my thanksful acknowledgement to Mr. Yamaoka 

 the artist, Mr. Otta the draughtsman, to the lithographic establishment of Gen- 

 gen-do and to that of the Tokio Daigaku under Mr. Kobayashi and finally to 

 the Nisshusha Printing Office for their painstaking cooperation in their respect- 

 ive departments. 



Tokio, December 1879.
