        "* * * * * WHERE TO BUY A DRESSING CASE.
        In no article perhaps is caution more necessary than in the purchase of
        a Dressing Case, for in none are the meretricious arts of the
        unprincipled manufacturer more frequently displayed. MECHI, 4.
        LEADENHALL STREET, near Gracechurch Street, has long enjoyed the
        reputation of producing a Dressing Case in the most finished and
        faultless manner. Those who purchase of him will be sure of having
        thoroughly-seasoned and well-prepared wood or leather, with the fittings
        of first-rate quality. The prices range from 1l. to 100l. Thus the man
        of fortune and he of moderate means may alike be suited, while the
        traveller will find the Mechian Dressing Case especially adapted to his
        necessities.--4. LEADENHALL STREET. * * * * *

        "Mechi,
        John Joseph (1802-1880)
        "businessman, agriculturist and City activist was
        born in London on 22 May 1802. His father, Giacomo, was from Bologna and
        held a position in the Court of George 111. Royal connections were
        maintained as John claimed an early acquaintance with Queen Charlotte
        and a fishing companion in the Duke of Sussex. As a youth of 16 he was
        placed as a clerk in a mercantile house in Walbrook, concerned with
        Newfoundland trade. He remained here for ten years until, having saved
        enough money, he opened his own shop in Leadenhall Street. Here, he
        designed the ‘Magic Razor Strop’, making enough money from the
        business in the 1830s to move to larger premises but which thereafter
        suffered when beards became fashionable. Despite this setback and not
        for the first time, Mechi reinvented himself. This time, from 1859 to
        1869, he went into partnership with Charles Bazan (Frederick Keats of
        Fortnum & Mason’s was a colleague) marketing a patent in shop
        window lamps at 112 Regent Street.
        "By this time he had began to construct a model
        farm at Tiptree Heath in Essex. This was the subject of extensive
        publications, including the best seller How to Farm Profitably
        (1857). The emphasis was on the use of deep drainage and steam power.
        "Surprisingly, perhaps, Mechi found time to marry
        twice: first in 1823 to Fanny Frost, and second to Charlotte Ward in
        1846. The combined product of both unions was several daughters and one
        son. He also gave his time to a number of other causes. He was member of
        the Council of the Society of Arts, Juror in the Department of Arts and
        Science at the 1851 General Exhibition and at the Industrial Exhibition
        in Paris in 1855, as well as founder of the Royal Agricultural Benefit
        Institution.
        "Within the City of London he was appointed as a
        Sheriff in 1856 and Alderman in the ward of Lime
        Street in 1858. His luck run out in 1866, with the failure of the
        Unity Joint Stock Bank, and a hapless connection with the General Life
        Assurance Office eventually forced the liquidation of his assets. He
        resigned his Aldermanic gown and after several bad seasons on the farm,
        developed diabetes. He died at Tiptree Hall on 26 December 1880 and was
        buried at the local church on the first day of the New Year."
