Thomas Marquois was a Huguenot, living in London in the last quarter of the 18th century. Around 1778, he invented a set of parallel scales that greatly simplified military sketching in the field. The set consisted of two scale rules and a right-angle triangle.

Although Marquois sank into obscurity after his death in 1802, his scales did not and Marquois parallel scales are described in nearly every English book on mathematical instruments published during the nineteenth century. Many of the best-known mathematical and scientific instrument makers offered them. Numerous examples are found in tool sales and antique shops.

In this monograph, the author outlines Marquois's life, explains how the scales were used, who made them and several later improvements. It includes Marquois's own instructions for their use.

A reprint on CD of the Directory of American Toolmakers, published by the Early American Industries Association.

The CD contains a list of approximately 14,000 toolmakers working in Canada and the United States before 1900. The 1999 print edition, which ran to 1200 pages, soon sold out but in response to continued interest the EAIA produced this convenient electronic version.

The main feature is the Directory itself in pdf format, listing toolmakers by Name, Location, Working Dates, Types of Tools made, Sources, Birth and Death dates and Trade Marks. Many entries include supplementary text giving more background and history of the companies listed. It is an invaluable resource for anyone interested in American tools and their makers.

The CD also includes sample articles from the EAIA journal The Chronicle and an index to its contents for 1988-2006
