This work was done in the laboratory of the department of Experimental Surgery of Northwestern University Medical School, with the cooperation and assistance of Prof. Robert Zeit and Drs. Wolfer, Violet Deason and Solmon. It is accomplished by the use of rings of metallic magnesium. PHYSICAL PROPERTIES AND METALLURGY OF MAGNESIUM Magnesium is a hard, silver-white metal, having a specific gravity of 1.75 and possessing a melting point of 800 degrees. As it tarnishes in the air the bright luster is soon lost, but the change is unimportant at the ordinary temperature. At a high temperature combustion follows, with production of the well-known brilliant white light. At ordinary room temperature the action increases and hydrogen gas is slowly liberated, the hydroxid of magnesium being formed at the same time. The action of water on magnesium is hastened by the presence of salts, such as sodium chlorid, from which it follows
