Latin

Etymology

Misspelling or alteration of original octārius (a New Latin coinage). Potential influences include analogy with the semantically related ordinal number octāvus (“eighth”), conflation with the form of the preexisting proper noun Octāvius (from octāvus +‎ -ius), or misreading of the similarly-shaped letters r and v.

Noun

octāvius m (genitive octāviī); second declension

(New Latin) Misspelling of octārius. (The pint (eighth of a gallon) in the apothecaries' system)

  "Calcem aquâ resolutam in retortam mitte, dein ammoniae hydrochloratem in frustula contritam et reliquam aquam adjice. Distillent liquoris ammoniae fluid unciae quin decim."

Notes

^ Everitt has misquoted the Pharmacopeia of 1836, which actually reads as follows: "℞ Ammoniae Hydrochloratis uncias decem, Calcis uncias octo, Aquae octarios duos; Calcem aquâ resolutam in retortam mitte, dein Ammoniae Hydrochloratem in frustula contritam et reliquam Aquam adjice. Destillent Liquoris Ammoniae fluidunciae quindecim." (Pharmacopoeia Collegii Regalis Medicorum Londinensis, 1836, page 56)
