Two oblong quarto vols. 111pp., paginated continuously. Moon's tactile alphabet, first published in 1843, uses raised embossing to convey the otherwise visual letters, numbers, and punctuation marks, taking advantage of possible abbreviations to streamline both production and reading. Moon's was the alphabet of its kind to be adopted widely, and was the most popular method of non-visual reading prior to the introduction of Braille. This edition of the Gospel of John, published sixty years after the Moon alphabet's first appearance, evinces its lasting usefulness. Volumes identically bound in half-cloth with marbled paper over boards and paper labels to spines. Moderate overall rubbing, pages toned as expected, chips to labels and two corners, else a very good and quite sturdy set, with only three copies in institutional holdings. Moon's Society label to front pastedowns.
