 say deductively what these 

 should be. The descrip- 

 tions I have been able to 

 examine are so wanting in 

 detail upon the crucial 

 points of the section, that 

 I can only make vague 

 identifications of parallel 

 features. 



The great anticlinal 

 throughout the zone of dis- 

 turbance in the Molasse 

 would seem to find its 

 counterpart in the Sivalik 

 Hills. Throughout the 

 whole North-west Hima- 

 layas these flanking hills 

 are connected with an an- 

 ticlinal axis, which gene- 

 rally runs along their 

 southern base, the southern 

 limb of the flexure having 

 been denuded and covered 

 by detritus. 



The remnant of bottom 

 beds of the Molasse series, 

 so frequently found along 

 the main boundary, be- 

 tween the Nagelfluhe and 

 the Secondary rocks of the 

 mountains, may be the 

 physical equivalent of the 

 Nahun band. As far as I 

 can make out, it is upon 

 the presence of these rem-

 of inversion of the younger 

 rocks at the contact has 

 been founded, and ex- 

 tended to such sections as 

 those of the Bigi and the 

 Speer ; but if my conjec-

 which in theSubhimalayan 

 region was arrested well 

 short of the mountain -
