Introduction and sections II and IV formulate moving-body electromagnetism relative to a stationary ether and introduce transformations of the equations. The 2021 date in the facsimile repository is the digitization date, not the publication date. The source is used to distinguish nineteenth-century ether dynamics from Albert Einstein's 1905 principle-based treatment.
