Details of Bores Nos. 1 to 11, etc. — continued . 
bore3 at about the same depth. They both result, evidently, from the upward 
passage of meteoric water impregnated with iron or lime respectively. From 
95-107 feet the strata is composed of a grit loosely consolidated by a deposit 
of marcasite. 1 Down to 124 feet the beds may be regarded as probably 
Pleistocene, but at 124-160 feet the character of the beds changes; the fine, 
grey, micaceous sand is equivalent to that in the previous bores with vegetable 
remains and estuarine foraminifera, and may represent the Upper Pliocene. 
True Kalimnan (Lower Pliocene) strata occur at 160-165 feet. From 165 
feet to near the base of this bore at 226 feet, the fossils indicate an admix¬ 
ture of Kalimnan and Janjukian strata, as indicated by the fossils Bothy- 
actis beaumariensis , Marginella muscarioides and Tylospira coronata (Kalim¬ 
nan), and Graphularia senescens, Echinocyamus ( Soulellina ) 'patella, and 
Pleurotoma selwyni (Janjukian). The glauconitic sand-rock of 226-235 feet 
probably indicates the presence of Lower Aldingan or Janjukian beds. From 
210-235 feet the Janjukian facies is stronger than the Kalimnan. 
On the whole, the samples from this bore show a greater admixture of 
fossils than from any other; an assortment accidental rather than natural.
