CONNAUGHT JOURNAL MARCH 3RD, 1823
Collectors of books will not be sorry to learn, that a few drops of oil of lavender will insure their libraries from mildew. A single drop of the same oil will prevent a pint of ink from mouldiness for any length of time. Past (sic) may be kept free from mould entirely by the same addition; and leather is also effectually secured from injury by the same agency.
