In the present notes, all crystal faces are treated according 

 to Dana's System of Mineralogy ; and all Japanese names are 

 transliterated according to the rules made by the Society for 

 romanising the writing of Japanese. Thus, all vowels are 

 pronounced as in Italian, and all consonants as in usual English 

 spelling. Special care must be taken to distinguish long vowels 

 marked with-, as in Ota and Ota, which are two fundament- 

 ally different names in Japanese. 



The statement of mineral-localities has usually been 

 restricted to the names of the village and province ; for more exact 

 and detailed statements, the reader is refered to the catalogues 

 of Japanese minerals, &c., in the Imperial Museum, of those ex- 

 hibited in the Chicago Exhibition, or of those sent to the Inter- 

 national Geological Congress of 1897. 



Authorities are mentioned in the case of many minerals ; 

 but references to periodicals published in Japanese have been 

 omitted. 



A. Elements. 



1. Graphite. 



Province Hida contains many localities of graphite and is 

 known as the principal source of this mineral in Japan. Ac-

 A peculiar occurrence of graphite in the shape of round masses 

 in a dioritic rock is found in the Piboro river in Tokachi Pro- 

 vince. Suzuki has given a list of graphite localities in Japan.
