NEW METHOD OF PRODUCING X-RAYS.

All entirely new method of producing X-rays of a most remarkable pane, trating power has been discovered, i! is claimed, by Air William David Coolulge, of Schenectady, Xew \ ork State. It is the result of three years’ research and utilises the principle that certain metals like platinum, when heated in a vacuum, give oh a steam of charged particles. 'With the aid of a powerful electric current these particles, or irons as they are called hy scientists, arc driven against a tungsten plate, placed within the vacuum tube. They strike this, and X-rays are produced. As Mr Gooliclge puts it, “The irons have bees stewed out of the heated metal.” Tim penetration of the rays depends or the speed with which they are driven against the tungsten plate. At s

demonstration before n score of pro minent American physicians ami phy-

sicists. rays were generated power nil enough to give full treatment in fifteen seconds. The usual time wit a the most powerful appro-:. ns is more than fifteen seconds. Complete destruction of living tissues- may be caused by an exposure of 3 minutes, and so remarkable is the control of the production of the rays by this method that at will the soft tissues of the body, the veins and nerves may he shown, or the densest part of the body may he pictured a hundred feet from the tube.
