JHG notes that the original manuscript of the BOM didn't have punctuation.
John H. Gilbert memorandum, September 8, 1892, MS 9223, Church History Catalog
. . . Every Chapter, if I remember correctly, was one solid paragraph, without a punctuation mark, from beginning to end.
Names of persons and places were generally capitalized, but sentences had no end. The character or short &, was used almost invariably where the word and, occurred, except at the end of a chapter. I punctuated it to make it read as I supposed the Author intended, and but very little punctuation was altered in proof-reading. The Bible was printed 16 pages at a time, so that one sheet of paper made two copies of 16 pages each, requiring 2500 sheets of paper for each form of 16 pages. There were 37 forms of 16 pages each,— 570 pages in all.
