Tincture of iodine has been employed as an antiseptic by hospital sur- 
geons since 1823. By modifying the surfaces to which it is applied, it 
usually improves the appearance of the pus, lessens its persity, and is, to 
4 certain extené, antagonistic to putr id infections. It disinfects, however, 
nd incompletely, causes severe pain when applie ed to open wounds, and
