{{ PREFACE. 



to add a large fraction of entries, to extend many of my own 

 notes and to modify the definitions given. 



With an active body of geologists at work our knowledge of 

 India is growing daily, and thus, like a dictionary in dealing with 

 a language, such a glossary as this must be out of date before 

 it is issued. Still, the notes have now reached a stage when they 

 might be of use to young students and, in spite of their short- 

 comings as well as their errors, they ought to be of more value 

 published than if kept any longer for mere private use. Publica- 

 tion is the only way to obtain the practical criticism of a large 

 body of workers, each of whom in his own sphere will be able 

 quickly to supersede each special entry. The critical remarks of 

 such workers will be welcomed and will be turned to account in 

 preparing future editions.
