II. — Note on a Phosphatic Layer at the Base of the Inferior 

 Oolite in Skye. By Horace B. Woodward, F.R.S., of the 

 Geological Survey.' 



AT the southern end of the great cliffs of Ben Tianavaig, south 

 of Portree, in Skye, the basement beds of the Inferior Oolite, 

 which contain large dogger-like masses of calcareous sandstone, rest 

 in a hollow of the Upper Lias Shales, owing to local and to a certain 

 extent contemporaneous erosion. Lining this hollow there is an 

 irregular and nodular band, two or three inches thick, of dark 

 brown oolitic and phosphatic rock ; a fact of interest, as instances 

 of local erosion are often attended by the accumulation of phosphatic 

 matter in beds, nodules, and derived fossils. 



Mr. George Barrow, who made a rough analysis of the rock, 

 estimated the amount of phosphate of lime at about 50 per cent. ; 

 and Mr. Teall, who examined a section under the microscope, noted,
