TIN FOIL'S THINNESS.

Tin foil, as well as lead foil, is believed to have been made in China long before it was known in Europe. It was first made by hammering bars of metal into thin sheets.

To-day the foil is made by automatic machinery, and must meet exact specifications. The foil for fine hand made bock paper will run 200 sheets to the inch, while that for use in radio condensers runs 4350 sheets to the inch and must not vary from that figure more than one forty-five-millionth of an inch. In the thinnest size 14,500 square inches are made from a pound of metal. The use of tin foil is constantly increasing.
