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 … more

Engineering Factors in the Ventilation of Metal Mines

Description: From Introduction Purpose and Scope of Report: "In the belief that the quickest and cheapest method of obtaining effective ventilation of metal mines with regard to air conditions that promote efficiency, health, and safety is through more general application of the engineering factors involved rather than by trial and error and this method of attacking ventilation problems will be facilitated by a simple, concise statement of these factors and the methods of using them, an attempt is made in t… more
