Excerpt from An Investigation of the Strength of Rolled Zinc An extensive series of tests of the strength of zinc plates was made by Dr. Oswald Meyer of Vienna*. The plates tested by him were all rolled at the zinc works of Cilli, in Austria. The plates contained from to 1 04 per cent of lead, to per cent of cadmium, to per cent of iron, from a trace to per cent of copper, and a trace of arsenic. Tests were made of (a) plates as received from the zinc works; (b) plates treated with nitric acid; and (c) plates subjected to heat treatment before test ing. The results of Meyer's tension tests of plates as received from the zinc works, are shown in Table 3. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
