1. "On a certain Fossiliferous Pebble-band in the ' Olive group' 

 of the Eastern Salt Eange, Punjab." By A. B. "Wynne, Esq., F.G.S. 



The principal object of this paper was to oppose the views recently 

 published by Dr. Waagen as to the age of certain boulder-beds in 

 the Salt Range of the Punjab. By that author these beds had been 

 considered contemporaneous with each other, and assigned to the 

 epoch of the Coal-measures, in consequence of the discovery by Dr. H. 

 Warth of carboniferous fossils, especially Australian forms of Conu- 

 laria, in nodules restricted to a particular layer in the upper part of 

 a boulder-bed in the eastern Salt Eange. Mr. Wynne adduced evi- 

 dence to show that the fossils in question occur, not in concretions, 

 as supposed by Dr. W r aagen, but in pebbles evidently derived from 

 an older series; and consequently there was no proof that the 

 boulder-bed in question was older than the Cretaceous Olive beds 

 with which it had hitherto been associated. 



The principal boulder-beds in the Salt Range were then briefly 

 noticed; those beneath the Carboniferous Limestone west of the Indus, 

 those near Amb and Sakesir peak, associated with the "purple 

 sandstone," " 06o^ts-beds," and " speckled sandstone," and those in 

 the eastern portion of the Salt Range, amongst the beds of the 

 " Salt pseudomorph zone " and " Olive group," being successively 

 passed in review, and their relations to overlying and underlying 

 strata explained. It was shown that boulder-beds and conglo- 

 merates containing pebbles and boulders of the same crystalline 

 rocks are not confined to one horizon. 



In conclusion, the resemblance of the rock, of which the pebbles 

 containing Conularice &c. were formed, to that forming some of the 

 " magnesian sandstone " and " Obolus-loeds " was pointed out, and it 

 was suggested that the pebbles in question may have been derived 

 from representatives of those beds formerly existing to the south- 

 ward. 



2. "On the Phosphatic Beds in the neighbourhood of Mons." 

 By M. F. L. Cornet, For. Corr. G.S. 



These beds are situate in the province of Hainault, near the town 

 of Mons (Belgium) ; the workings have increased of late years, and 

 in 1884 yielded 85,000 tons of phosphate. 



They occur in the Upper Cretaceous, which is exceptionally well 

 developed in the district, filling a trough in the Carboniferous rocks,
