 tion of Indian Geologists. 



The great variety of the rocks there exposed, the picturesque beauty 

 of many parts of the country, and the early discovery of fossil remains, 

 probably led to this. It has therefore been thought desirable to preface 

 the following report by a brief sketch of the principal labors of our

 Captain Dangerfield, and is appended to Sir John
