The first edition of a popular work that went through thirteen editions, each building upon the previous one. Like the later editions by Thomas Hall (himself an instrument maker), this Davis edition sports a two page instrument catalog in the rear many of which are used in the described experiments. Predating the best scientific instrument catalogs of the period (Pike's Scientific and Medical Instruments in 1848 and 1856), this text illustrates some of the earlier instruments available to practioners.

"The frontispiece consists of two copper-plate engravings, one printed from an egraved plate, and the other from an electrotype copy taken from it in the mode described on page 204. The engravings are instrudced for the purpose of showing the accuracy of the copies obtained by this process." (verso of half-title)

OCLC entry 2411017 adds the following: ""The book contains a full description of the electrotype process, critical to many subsequent photomechanical patents and methods ... The electrotype process was important in photomechanical printing in that it was first used to copy daguerreotypes and was also used in experiments as a printing surface. Eventually Paul Pretsch used it with his photo-galvano-graphic process, and it was used continuously thereafter as a device to duplicate surfaces for printing in practically all the relief processes and some intaglio."--Hanson Collection catalog, p. 8"
