Here in verse 38, the compositor for the 1905 LDS edition accidentally set “the eighty and fifty year”, replacing fifth with fifty. This typo is an instance of perseverance of the ty at the end of preceding eighty. This same number was correctly set in the preceding verse (that is, “in the eighty and fifth year”). Interestingly, the typo in verse 38 was not caught when the stereotyped plates were corrected prior to publishing the third printing of the 1905 edition (in 1907).
Summary: Maintain in Helaman 11:38 the occurrence of fifth in the compound ordinal number “eighty and fifth”.
