Through the kindness of Mr. Tsunashirö Wada, I have been 

 allowed to study his collection of Japanese minerals, which 

 surpasses all others of the kind both in magnitude and complete- 

 ness. Moreover, he has given me much necessary assistance and 

 advice in writing the present notes, which consist of short ac- 

 counts of the characters and occurrence of minerals in Japan, 

 with special reference to his collection. I wish therefore to ex- 

 press here my most cordial thanks to him. 



Next to Mr. Wada's collection, are to be mentioned that of 

 the Science College of the Imperial University of Tokyo, that of 

 the Imperial Museum in Ueno, Tokyo ; and those of Messrs. Ko, 

 Sasamoto and others ; as being the most important collections of 

 Japanese minerals. Papers connected with these specimens are 

 scattered through the Journal of the Geographical Society of Japan, 

 begun in 1889 ; the Journal of the Geological Society of Tokyo, 

 begun in 1893 ; the Journal of the Science College, Tokyo, begun 

 in 1888 ; and other Japanese periodicals ; besides well-known 

 foreign publications containing mineralogical descriptions.
