Geological Map of Captain Herbert's Himalaya Survey. 



With the present number the Editors of the Journal have the ex- 

 treme satisfaction of presenting to its readers, and to the scientific 

 world in general, Captain Herbert's Geological Map of his Survey, of 

 which the Report was published by the late Editor and Proprietor, 

 gratis to subscribers, as a supplementary number to Vol. XI of the 

 Journal.* The introductory notice to that report will fully explain 

 under what circumstances it was obtained and published. It is to 

 the attentive recommendation of the Government of India, and the ever 

 ready assistance of the Court of Directors, that the Asiatic Society and 

 the scientific world are indebted for this noble proof of what has been 

 done in former days by the Government for the advancement of this 

 branch of science ; and if it be considered that the Map and Memoir now 

 date nearly twenty years back, (the Survey was of course previous to 

 it,) and that it is still the only connected geological sketch we have of 

 this great and interesting tract of country, where so many magnificent 

 geological problems yet lie unsolved, and perhaps even unthought of, 

 its importance as a preliminary draft for more detailed and accurate 

 delineation, may, as we have elsewhere stated,f be best appreciated by 

 those who can remember or refer to the geological labours of Smith and 

 the earlier Continental geologists, not many years before its date. We 

 should not also forget that the Report itself was but a first one, and 

 therefore, like the Map, but a sketch of what more detailed and minute 

 examination are wanting to render perfect. — Eds. 



* A large margin has been purposely made on the left hand margin of the plate, so 

 that it can be taken out of this number, and pasted into the volume, in its place at the 

 end of the Report, by those who have it bound up.
