GEOLOGICAL SURVEY OF INDIA. 



On the Geological structure and relations of the Southern portion of 

 the Himalayan range between the rivers Ganges and Ravee, by 

 H. B. Medlicott, a. b., f. g. $., Geological Survey of India. 



Chapter I. — General description of area and rocks. 



A treatise of which the Himalayas form the subject bears on its 

 title-page a sufficient recommendation to a large class of readers. 

 Many causes, mythical as well as scientific, have tended to spread, even 

 among popular readers, a deep and general interest in all questions 

 relating to the physical history of this portion of the globe. The follow- 

 ing memoir is, primarily, a record of geological

observations ; but, as a work of systematic geo- 

 logical observation could not be carried on without implicating many 

 questions in physical geography and other kindred sciences, this report 

 treats also of these subjects in so far as they appear to be connected 

 with the geology of the district. There must necessarily be many 

 imperfections in a work which has been conducted on a very limited 

 scale, when compared with the whole region involved ; and general 

 conclusions must be considered as more or less premature which are 

 hazarded upon a partial review of facts. While I would claim a gene- 

 rous indulgence for these imperfections, — imperfections which depend on 

 the scanty state of our knowledge of the Himalayas, — I would remind the 

 reader that I also make them an apology for introducing many facts
