NOTICE. 



assemblage of cretaceous rocks at Chichali was taken from 

 his own most distinct expression of it in the tabular list at 

 p. 276 of the Salt-range memoir. The statement regarding 

 the unconformity at the Indus was taken from his admirable 

 illustration of it in his ideal section at p. 69, such sections 

 being always understood to represent the original conditions 

 of the deposits, unaffected by dislocations. The word ' un- 

 conformity ' is used in the manual, as it is defined in the 

 glossary appended thereto, to include marked overlap — the 

 absence of deposits that are largely developed in adjoining 

 ground. Mr. Wynne uses it in a restricted sense only ; and 

 from his own type sections he appeals to obscure passages 

 in his text that might mean something different. But even 

 granting the facts he would make of such importance — 

 the few inches or feet of conglomerate between the 

 limestone and the salt-marl at the Indus, and the ab- 

 sence of denudation at the top of the nummulitie group 

 in the east Salt-range — -unconformity, as required in the 

 manual, would hold good. 



6. As this notice has to appear, one specific caution 

 may be added, as to the use Mr. Wynne makes of the term 

 Subathn at p. 56 and elsewhere. The Subathu group was 

 instituted for the nummulitie rocks at Subathu, brought 

 to notice by Vicary. They there rest directly upon the 

 slates of the lower Himalaya, and pass up transitionally 

 into the red clays of the Dagshai group. The calcareous 

 element is very subordinate, at the base of the group, in 

 this its original area. Erom Subathu it has been traced 

 interruptedly to the north-west, having the same composi- 

 tion and relations, into the Jamu sub-Himalayan region, 

 and its basal beds here have been specifically identified 

 (Records, IX, p. 57) with the lowest nummulitie beds at the
