Norwegian ores. It is concluded that, owing to the abundance of 

 water-power and absence of coal, the building of ordinary blast 

 furnaces would be an economic mistake, since the fuel-consumption 

 in an electric furnace is approximately only about one-third of that 

 in a blast-furnace, and water power is cheap. It is estimated that 

 the power consumption in an electric furnace is about 2,200 kilowatt- 

 hours per ton of pig, which is equivalent to 3 "98 tons of pig per 

 kilowatt-year, or 2 - 92 tons per horse-power-year. Hitherto, the 

 Swedish electric furnaces have been largely worked on charcoal, but 

 coke is now extensively employed and gives good results. It is 

 considered that small furnaces of the Tinfos type, working at about 

 1,500 kilowatts are not quite so economical as the larger Electro- 

 metal furnaces of 3,500-4,000 kilowatts, but under certain circum- 

 stances they are perhaps better suited to a budding industry, being 

 altogether on a smaller scale and needing less capital outlay. 



From the data here supplied it is clear that in a country like 

 Norway, with no coal and abundant water-power, electric furnaces 

 offer great possibilities for the production of pig-iron for steel making 

 for home consumption during periods of stress like the present time, 

 when freights are high and dumping impossible, but it remains to be 

 seen whether they will be able to compete with imported manufactured 

 and half-manufactured goods on the return of more normal conditions 

 of foreign competition and cheaper low-grade raw materials worked 

 on a very large scale in England, America, and Germany.

V. — Report on the Geology of the Hohoro District, Papuan 

 Oilfield. By W. G. Langford. Bulletin of the Territory of 

 Papua, No. 4, 16 pp., with 12 figs, and maps. Melbourne, 1918. 



IN this report Mr. Langford gives an account of the physiographic 

 features and geology of part of the Yailala oil-bearing district of 

 Papua, where the existence of gas-blows has been known for some 

 time. The essential structure is an elongated dome or anticline 

 traversed by faults and consisting of sandstones, mudstones, and 

 limestones, with occasional seams of lignite of Middle or Tipper 

 Miocene age. The rocks are highly fossiliferous and the fossils are 

 described in a separate report. Sites have been selected for trial 

 bores, and development is now in active progress.

1. " On the Dentition of the Petalodont Shark, Climaxodus.'" 

 By Arthur Smith Woodward, LL.D., E.R.S., P.L.S., E.G.S. 



The author describes the nearly complete dentition of a new 

 species of Climaxodus from the Calciferous Sandstone of Calderside, 

 near East Kilbride (Lanarkshire), now in the Royal Scottish 

 Museum, Edinburgh. Nearly all the teeth are borne on the
