Elmsly Lauchlan

Elmsly Lauchlan began his paper with a somewhat trenchant statement The modern manufacturer, frequently faced with opposing problems of economy of production and the competitive necessity of a consistently high standard in the finished product, must be interested in methods which give accurate information concerning the various processes which lead up to the final product. For it is this information which enables him to control...both the quantity of the constituents and the quality of the product.
