Abstract :
The Engineering Societies Library has to thank Mr. E. L. De Golyer, Vice-President of the Americau Institute of Mining and Metallurgical Engineers, for an unusually interesting addition to its collection of early engineering books. Mr. De Golyer´s gift is a copy of the rare first edition of Albaro Alonzo Barba´s “El arte de los metales,” published at Madrid in 1640, the earliest work published on American metallurgy.
