To Detect Blood-stains
It is said by Professor Bloxam, of London, that a mixture of tincture of guaiacum and a solution of peroxide of hydrogen in ether produces instantly, with blood or blood stains, a beautiful tint of blue. He had taken a single lint fibre, on which was a stain of blood scarcely perceptible, that had been made twenty years before, and he found that the test produced immediately the characteristic blue color, which was easily detected on a microscopic examination.
