MICROBES AND MONEY.
How microbes literally swarm on the coins we carry in our pockets and pay out and receive every day of our lives, is shown by the figures obtained as the result of experiments by M. Marc Langlais, which are published in the Matin. M. Langlais washed various pieces of money in a fixed quantity of sterilised water. Taking an average, a cubic centimetre of the water in which » bronze
fo centimes was was/Ml' wouW disclose no fewer than 760,000 bacteria, 3 per cent of which was Jhouldinesir, The nickel 25 centimes yiei&ed 140,000 bacteria, 2 per cent of which was mouldiness. For silver twotfranc piecee the figures were 160,000 atid 1 per cent; gold twenty-franc pieces, 220,000 and 0 per cent; banknotes, 1,200,000 and 8 per cent. I'bo adopition of nickel coinage constituted «■ very appreciable step towards real 1 hygiene in m&ney, since the 25 centimes showed fewer microbe inhabi-" tants than any other coins. In contrast, the water in which a much used 50-franc (£2) n'ote had been laved supplied more tharf three million bacteria.
