Iron Sheets Thinner Than Paper.

Philadelphia Press. .... A competition has for a long time past been carried on among the English ironmasters as to the degree of thinness towhfclrcold Tron eo-u-ld-be-rolled. In one case the sheets have been rolled to an average thickness or thinness of the eighteen hundredth part of an inch—in other words, eighteen hundred sheets of this iron, piled one upon another, ,would measure only one inch in thick ness, And this marvelous fineness cf work may be more readily undei* stood when the fact is borne in mind that the great number of t welve hundred sheets of the thinnest tissue paper measures a slight fraction over an inch. It also appears that these wonderful iron sheets were perfectly smooth and easy to write upon, notwithstanding the fact of their being porous when held up in a strong light.
