would be lime ; but the Agricultural Society having obtained 
analyses of several of the Wold soils, by Mr. J. Spence, of 
York,* it is found that the unchalked soil only contains of 
carb. of lime and carb. of magnesia, together of a grain 
per cent, while the chalk itself from Hessle Cliff contains 
90 per cent. carb. of lime, Sj% carb. of magnesia, together 
98^ per cent. ; so that it is only by the consideration before
