摘要

The familiar metallic taste of blood was explained scientifically only in the mid-eighteenth century. An Italian chemist and physician in Bologna, Vincenzo Menghini, roasted the blood of various birds, fish and mammals, including humans. He powdered the residue and passed a naturally magnetized lodestone close to the dried blood particles. Some were magnetically attracted, suggesting the presence of iron. Science writer Hugh Aldersey-Williams successfully repeated Menghini s experiment in his kitchen using blood from chicken livers, a low oven and a moderately strong magnet. But why, he asks, did Menghini imagine that iron would be present in blood? The physician must have known that people with blood disorders were sometimes advised to take iron salts. In the sixteenth century, a principal iron ore was named haematite - the prefix 'haem being derived from the Greek for blood. Western alchemists paired iron with the red planet Mars.
