Abstract
April 27, 1844.—The aneroid barometer was the invention of a Frenchman, Luoien Vidie, and was patented in England in the name of De Fontainemoreau, merchant, of London, on April 27, 1844. The advantages that it possessed over the mercury instrument, especially as regards portability, were apparent directly its accuracy for general purposes had been tested, and it was soon extensively adopted, especially in Great Britain.
