THE UNDERGROUND FORM OF FLOOR OF GANGETIC TROUGH. 65 



CHAPTER IV. 



THE UNDERGROUND FORM OF THE FLOOR OF THE 



GANGETIC TROUGH. 



The latitude stations on the Gangetic alluvium are ranged 

 across the plain in four series running north and south, and a more 

 scattered group in the Punjab. Of these five series, only two are 

 complete, in the sense that they are continued across the northern 

 boundary of the alluvium into the region of the Himalayas, but 

 it will be more convenient to begin with another series, which forms 

 a remarkably complete series, extending from the northern boundary 

 of the alluvium across the plain, and into the Peninsular rock area 

 to the south, in the neighbourhood of the 81° meridian of east 

 longitude.
