    Bruce,

    I suppose it is called "quick silver" in English, and there are reasons
    for this:-)

    And it is prohibited for air transportation.
    Mercury barometers completely disappeared from eBay and
    from all scientific equipment sellers about 5 years ago.
    Even mercury (medical) termometers disappeared.
    When I found this, I urgently bought one in Ukraine,
    while they still exist. An electronic (medical) termometer is much less
    accurate. Same applies to the devices measuring blood pressure,
    or any kind of pressure.
    
    Nevertheless I was able to buy one pound of mercury in an onlune chemical
    store (I was thinking of silvering mirrors with an ancient recipe,
    or for use in an artificial horizon, and hurried to buy while still
    available:-)
    
    Alex.
