INTRODUCTORY. 1 7 



Merewether, appeared in the Transactions of the same Society, Vol. x, 

 page 284. This is an account of a severe and destructive earthquake in 

 the Marri Hills north of Jacobahad. A notice of other earthquakes 

 felt in Sind and its vicinity in the year 1851 is added. 



In the Quarterly Journal of the Geological Society for 1853, Vol. ix, 

 page 349, there is a letter " On the Geology of a part of Sind," written by 



Frere 1853 H ' B ' E * ^° W Sir Eartle ) Frere > to Colonel Sykes; 



In this letter mention is made of a collection of 

 bones of mammalia procured by Mr. Arthur Young, Deputy Collector of 

 Sehwan, from a locality " in the hills south-west of the Manchhar Lake 

 and Sehwan, and about half-way to Shah-billawall, but on the east side 

 of the Habb river." A few notes are also given of the rocks seen on the 

 hill road between Karachi and Sehwan, and a section of a nummulitic 

 range, showing an. anticlinal of nummulitic limestone, on one side of 

 which, resting on the limestone, are " variegated marls and shales, or 

 indurated mud beds/'' and on these again " beds of gravel and sandy con- 

 glomerate." Each of these groups is shown to be unconformable to the 

 other. With the exception of the unconformity, which is rather unusual, 

 and perhaps is due to an error on the part of the draughtsman, similar 

 sections do occur in many places on the road mentioned, and the relations 

 of the rocks are precisely as shown in the figure. The locality for 

 mammalian bones has not been re-discovered, and it is impossible to avoid 

 suggesting whether some mistake may not have been made about its 

 position, and whether the bones did not really come from the Laid range. 

 In all probability the Mr. Young who collected the bones is the same 

 as the Dr. Young mentioned below as having presented a collection to 

 the Asiatic Society of Bengal through Dr. Spilsbury, who made an 

 extensive collection in the Nerbudda valley.
