On this confirmatory evidence I adhere to the view expressed in 

 my paper as to the derived or remanie character of the Gonularia 

 layer, until something more conclusive is brought forward than has 

 been yet produced. 



The " Olive group " of the Salt-range which contains this Gonularia 

 layer, from its circumstances of position and from a few of its fossils, 

 found in a determinable state, was classified by Dr. Waagen and 

 myself as probably of Cretaceous age, before he left the Punjab. 



It has been recorded for years that certain Boulder-beds, lying 

 just beneath this Gonularia layer, and included in the Olive group, 

 contain glaciated blocks, and resemble the Talchir Boulder-beds of 

 the Gondwana series in Peninsular India ; also that there are in 

 other parts of the Range, and at different vertical positions in its 

 sections, Boulder-beds of very similar aspect. 



I have never found reason to believe that the stratigraphic 

 relations of these Salt-range Boulder-beds supports the idea now 

 advanced, that all occur upon one and the same horizon ; and I must 

 say I am still unconvinced of the fact, while admitting that this 

 would be both important and interesting if proved.

THE PALiEONTOGRAPHICAL SOCIETY. 

 Sir, — The fortieth volume of the Memoirs of the Palasontographical 

 Society is now in progress ; with the current year the series will 

 have completed the number generally assigned to a period of pro- 

 bation. That it has well endured the trial of time none can deny. 

 The unremunerated labours of many of the leading paleontologists 

 of Britain have enriched their fellow- workers with a series of mono- 

 graphs, sometimes dealing with various genera or classes, some- 

 times presenting a synoptic view of certain portions of the fauna or 

 flora of an important Geological period. To these workers and to 

 all who have taken an active part in the direction of the Palasonto- 

 graphical Society, geologists, not of Great Britain only, are deeply 

 indebted. Never, we may confidently assert, has so magnificent a 

 series of admirably illustrated monographs been placed in the hands 

 of students or at so low a price. For an annual subscription of one 

 guinea, a bulky volume is received, containing usually about thirty 

 plates and three hundred pages of letterpress. At the present time 

 monographs are in preparation or in progress on Pleistocene 

 Mammals and Old Eed Sandstone Fishes, on Jurassic Ammonites 

 and Gasteropods, on Cretaceous Starfishes, on Palasozoic Sponges and 

 on the Flora, both of the Carboniferous and of the Eocene periods. 

 There is evidently no failure either in material or in writers. More- 

 over, up to the present time the Society has successfully paid its way 

 and has occasionally had a small balance to the good. Death how- 

 ever of late years has unfortunately removed many of the original 

 subscribers, and new members come in more slowly than might have 

 been expected. Accordingly the Secretaiy announced at the last 

 meeting of the Council that very shortly, unless there was a sub- 

 stantial increase in the number of subscribers, the quantity of matter
