INTRODUCrOllY. 38 



obscured any recoguisable break between the Salt Rang-o eocene 

 (nummulitic) and overlying sandstone and clay series, are mentioned. 

 A section through Diljaba mountain is given for comparison with the 

 Dandli section of Mr. Medlicott^s Sub-Himalayan Report; but subse- 

 quent examinations have so altered the reading of the latter that much 

 of the disparity noticed has been removed, and if the Dandli hill lime- 

 stone had proved itself nummulitic by any fossil remains the similarity 

 between the two sections would be striking."^ 



The suggestion at p. 69 regarding possible differences connected 

 with the production of the Himalayas of the Simla area as compared 

 with those mountains nearer to the Upper Punjab appears to coincide 

 with the later and bolder announcement of Mr. Medlicott, that these 

 two areas of the Himalaya have been elevated at different periods. 

 (Records, vol. ix). I did not venture to say so much. The elevation of 

 the Salt Range was doubtless connected with that of the Western 

 Himalayas.

When this memoir was published, I was absent on furlough and had 



not the opportunity of either correcting the proof sheets or bringing 



some of the observations into connection with the most recent views 



developed by the Survey regarding other regions geologically connected 



with this. Thus the classification of the upper tertiary beds was 



influenced by the supposed discovery that the Siwalik fauna extended 



downwards far into the Nahan group. On more recent information 



the Upper Tertiary beds should have been shewn in the table at page 21 



as Siwalik instead of Nahan; and the rocks immediately below these,
