NATURAL SCIENCE. 



April, 



To me it seemed perfectly clear when I expressed myself as follows : 

 " One of the most conspicuous beds, palaeontologically as well as 

 petrographically, is a ferruginous conglomerate, upwards of lo feet in 

 thickness. This bed may be distinguished a long distance off as a 

 dull-red band, running, in a continuous line, across ravines and hills. 

 Besides numerous other vertebrate remains, such as Rhinoceros peri- 

 mense, etc., one of the commonest species is Hippotheviuni antelopinum 

 Caut and Falc. of which numerous isolated teeth can be found. 

 While stooping to pick up the fine lower molar, which is figured in the 

 accompanying plate, my attention ivas drawn to some curiously shaped fiints 

 partly imbedded in the ferrtiginoiis conglomerate.'''' (Italics not in original.) 

 Originally I believed this bed to be Miocene. Subsequent exami- 

 nations, however, have proved that Dr. Blanford's doubts as to the 

 age were well founded, and that it must be considered as Pliocene. 

 It would lead too far if I were to give here the proofs for this view, 

 and for details I must refer the readerto my Memoir on the petroleum-

field of Yenangyoung, which has unfortunately been greatly delayed 

 in publication, but which I trust will soon be before the public. 



In March, 1893, while I was still engaged in the examination of 

 the country around Yenangyoung, Mr. R. Oldham visited me at that 

 place, and desired, amongst other subjects of interest to him, to see 

 the locality where the flakes were found. I pointed out the exact 

 locality, where we spent at the outside a quarter of an hour, without 

 however finding any other flakes; nor did we find any fossil bones or 

 teeth, I might say as a matter of course, as I had repeatedly so well 

 searched the place myself that not a single specimen could have been 

 left unnoticed. We then proceeded further south ; I showed Mr. 

 Oldham the locality where countless specimens of Batissa [Cyrena) 

 petrolei and Batissa {Cyrena) crawfurdi occurred in pockets at the base 

 of the ferruginous conglomerate. At another locality we found frag- 

 ments of fossil bones. Eventually we came at the extreme end of 

 the Yenangyoung dome, near a hill called Minlin (on the maps it is
