The Principles and Practice of Sampling Metallic Metallurgical Materials: with Special Reference to the Sampling of Copper Bullion

Description: From Introduction: "In this report considerable space has been devoted to general and theoretical principles on the ground that under modern conditions the best results in any field of activity can be attained only with the aid of an adequate knowledge of the best theories underlying the practice. The diffusion of such knowledge in the field of sampling metallic metallurgical materials appears to have been quite insufficient, and it is felt that when the principles involved are once thoroughly comprehended their universal application will be appreciated, so it will make no difference whether pig iron of gold bullion is offered for test.
