Casselberry's discovery was a less expensive method of decomposing liquids. He used electricity and during his experiments found that two decomposing cells attached to a galvanic battery or magneto-electric machine will generate twice the gas as a single cell. Prior to Casselberry's experiment it had been assumed that the resulting gas would be half as much as the electricity would be split into the two cells. This small pamphlet has no imprint information, it was likely a small run, probably for private distribution among colleagues.
