Weights and measures being small antique objects with a background of great interest, have become an ideal and popular subject for the collector. The story of how they came to be used and developed is a long and fascinating one and this book not only tells that story but provides much information for collectors. In addition to their history, the book explains the reasons for the shapes, sizes and materials in which weights and measures are found. It also considers the legal controls exercised over the use of weights and measures and how these add to the interest of collecting. The many illustrations of verification stamps will assist collectors to identify and perhaps date examples in their own collection.
Book 55
When prehistoric man picked up his first stone he would not appreciate that its weight was due to the effect of gravity on its mass. Soon, though, he would learn that large objects were sometimes lighter than smaller ones and that he would need an aid to help compare weights and values. Today, we accept weighing as part of everyday life, using its principles as measures of our idea of justice, but giving methods of weighing little thought. Weighing, however, is an ancient art, which has exercised the minds of philosophers, scientists, engineers and even the dishonest for at least 6000 years. This book shows how men strove to produce a machine which would compare more accurately, or more quickly, or would meet a special need or perhaps sell even more cheaply. With the aid of many illustrations and non-technical language, some essential knowledge of the principles of weighing is provided.
