On treating some pure indigo-blue with alcohol, to which an alkaline solution of protoxide of tin was added until it dissolved, then adding acetate of soda and digesting at a moderate heat, the indigo-blue after some time ceased to be deposited on exposure to the air, or even agitation ; it had entirely disappeared. The same thing occurred when formiate of soda was employed in the place of acetate. It was evident, therefore,...

For Scotland, and for Ireland, it was only possible to found an estimate...
