ers for Mrs. Ryves, preparatory to her case coming on in November next, in the Probate Court, I accidentally found, among other manuscripts, the following:
London, January 3, 1772.

From recent statistical returns of the mineral riches of France, it appears that the number of coal mines worked is four hundred and ninety, and of iron mines two hundred and two.
Of other substances there are two hundred and forty-seven mines; comprising graphite, bitumen, rock- salt, antimony, manganese, lead, silver, copper, tin and zine, isolated or in combination.
The concessions of coal mines extend over five thousand two hundred and twenty-six square kilometres (each two hundred and forty-seven acres) in forty-seven different departments.
