Post dates the death of Jerome Kidder, (who died on May 13, 1879) with a testimonial on page 53 dated Aug 12, 1884. Perhaps most valuable today as a trade catalogue/marketing document, It begins with some theory about electro-allotropic physiology and shows some examples of how it manifests to users. Then come earned awards and boilerplate how applications work from previous catalogs. Pages 26-45 are excellent wood engravings in the typical trade catalogue style, with prices and explanations of Kidder's electrical apparatus, showing current offerings. Then follows a few pages of testimonials. Other catalogs from this time period also include excerpts from scientific research used in an attempt to differentiate Kidder's offerings from period quacks. But that "section" is not in this example.
Not in Romaine or Davis and Dreyfuss. Edmonson (American Surgical Instruments, the History of their Manufacture...) records Jerome Kidder Mfg Co at 820 Broadway, New York from 1882 to 1900. This edition not in OCLC/Worldcat.
