Excerpt from A Manual of Practical Assaying
A little more prominence has been given to the English system of grain weights, as English assayers are more familiar with these than with the metric system in use on the Continent and, as far as possible, the decimal system has been adopted, the grain being taken as the unit. SO many valuable memoirs on assaying and metallurgical subjects are published abroad that it has, however, been found impracticable to adhere universally to grains.

Excerpt from A Manual of Practical Assaying
The rapid progress of Science renders a metallurgical work antiquated in a comparatively short period, so that the last (second) edition of the late Mr. Mitchell's 'Manual of Practical Assaying,' published in 1854, is no longer in accordance with our enlarged knowledge of the subject.
In this edition are incorporated all the late important discoveries in Assaying made in this country and abroad, and special care is devoted to the very important Volumetric and Colorimetric Assays, as well as to the Blowpipe Assays. Most of the chapters are entirely re-written, whilst the chapter on Crystallography - being a subject only remotely bearing on Assaying - is left out altogether. On the other hand, in some cases, it may seem that by treating of purely analytical details the limits of Assaying have been exceeded. But these departments are so closely related as to make it impossible to fix the line of demarcation between them. Moreover, chemistry is cultivated by almost all to whom this work is of interest or service, so that it is hoped these amplifications will add to its value.
