[April, 



ing it requires 10 cwt. of limestone 

 to the ton of iron, and taking the 

 price of coke laid down on the 

 spot at 15s. per ton, it has been 

 estimated that the cost of smelting 

 pigs, including royalties, labour, 

 &c, would be about 21. 12s. The 

 carriage into South Staffordshire 

 would be, in addition to the above, 

 3s. per ton. 



A more extensive district, and 

 one which also possesses the ad- 

 vantage of yielding the ore over a 

 large surface without any cover, 

 occurs to the west and south of 

 Banbury, extending as far as the 

 village of Hook Norton. Railways 

 are already projected over this 



tract, occupying an area of per- 

 haps 25 square miles ; and visions 

 of furnaces rising amidst the church 

 steeples and farmsteads of this 

 hitherto unsophisticated region are 

 floating before the minds of some 

 of the residents. For ourselves, 

 we look upon this as reserve 

 ground, not likely to be opened up 

 for many years. But who shall 

 venture to say what may or may 

 not happen with the mines of the 

 Cleveland hills, and furnaces of 

 Teeside blazing away before our 

 eyes, where all was silent and 

 motionless a few years since ?

On the Occurrence of a Tertiary Species of Trigonia in Australia. 

 By H. M. Jenkins, F.G.S. 



The very interesting discovery of a 

 species of Trigonia, in the Tertiary 

 deposits of Australia has in England 

 remained entirely in the back- 

 ground, and I have been several 

 times surprised at finding students 

 of Tertiary palseontology, generally 

 au couraut with the progress of 

 their special branch of science, un- 

 acquainted with the circumstance. 

 Its importance, in a theoretical 

 point of view, is beyond all ques- 

 tion, hence the deep interest always 

 exhibited by those to whom I have 

 spoken on the subject. I trust that 

 it will also justify my bringing for- 

 ward in your Journal a subject not 

 quite new, although very nearly 

 unknown. 



On the Southern Coast of Aus- 

 tralia is a series of Tertiary deposits 

 of vast extent, the exact age of 

 which is somewhat doubtful. Cer- 

 tain portions are said to be older 

 than others, but their palaeontology 

 has not been sufficiently studied to 

 enable one to speak very definitely 

 on the probable correctness of this 

 view. The older beds have been 

 called Upper Eocene by Profes- 

 sor M'Coy, and the younger Lower 



Miocene. But an examination of a 

 collection from the beds of Muddy 

 Creek, sent over by the Rev. Julian 

 E. Woods, and marked "Eocene," 

 induced me to believe that the 

 shells contained in the collection 

 indicated a Miocene, or even later 

 age (using the term Miocene con- 

 ventionally), and were allied partly 

 to the recent Philippine fauna, and 

 partly to European Miocene species. 

 There is great difficulty in corre- 

 lating Tertiary deposits so far away 

 with those of Europe; but as Dr. 

 Duncan has since published an 

 opinion very similar to that just 

 stated, founded on the Corals and 

 Echinoderms, and Professor Rupert 

 Jones is also inclined to the same 

 view, from an examination of the 

 Foraminifera, I think we cannot be 

 very far wrong. Hence we may 

 consider the Trigonia to which I 

 have referred as being doubtfully 

 Miocene, perhaps newer, its age 

 being well enough defined by the 

 Austrian term Neogene, which in- 

 cludes both the Miocene and the 

 Pliocene. 



The newest species of Trigonia, 

 with the exception of the recent
