Description:

Printed title page on inside cover and [22] pp. With text illustrations and large foldout engraved plate: "Analytical Table of Mechanical Movements," illustrating classification of 178 mechanisms of the computing scale. 28x28 cm (11x11") original brown cloth stamped in blind and gilt.

The computing instrument itself is not present with this copy. Instruction manual for one of the first circular slide rules sold in the United States. It was introduced by Aaron Palmer of Boston, who made a prototype in 1841, took out a copyright for a computing scale in 1843, and published an account of it in 1844. He exhibited both the original and a smaller version at the 18th American Institute Fair, held in New York, N.Y., in 1845. There it may have attracted the attention of John Emery Fuller, who acquired rights to the instrument and published an account of his improvements. He also added the time telegraph, which he had copyrighted in 1845. Scarce.

General wear and soiling to cloth, some rubbing and fraying to edges; toning and offsetting to interior and chart; good or better.
