The Iron Ores of the English Secondary Rocks [title only given in list 

 for 1886 ; after showing that the amount of iron-ores raised from Secondary 

 rocks has increased about nine-fold in thirty years, and now constitutes 56 per 

 cent, of the total output, and giving a short bibliography of the subject, the 

 author proceeds to describe in detail the most important sources of iron-ores in 

 the Secondary strata ; these include in the Lower Lias (A. semicostatus zone) 

 the Frodingham bed in North Lincolnshire ; from the Middle Lias the Cleve- 

 land ironstone, the Main Seam being in the A. spinatus zone, the Bottom 

 Seam in that of A. margaritatus ; the deposit at Caythorpe in South Lincoln- 

 shire is also Middle Lias ; in the Lower Oolites come the Top Seam of 

 Cleveland and the magnetic iron-stone of Rosedale in that district, also the 

 ore near Lincoln ; to the Lower Cretaceous belong the iron-ores of Claxby in 

 North Lincolnshire, with Pecten ductus ; the concluding part of the paper 

 discusses the origin of these ores, the carbonate of iron being supposed to 

 have replaced carbonate of lime in ordinary limestones]. Trans. N. of Eng.
