After si x years of arduous and unremitting research, two German scientists, Di st Ruska and Dr. E. von Borris, who have been working at the laboratory for electronic optics of the Siemens and Halske A.) G. of Berlin and the university medical clinic of the Charite at Berlin, have succeeded in perfecting an instrument known as the ultra-ultra or electronic microscope.
By enabling linear magnifications of 30,000 to be reached by comparison with a maximum of only 2,000 attainable with the most refined optical microscope known to modern science, this new instrument will enable medical and physical science to explore worlds of infinite minuteness, which had up to now been far beyond the range of human investigation. Scientifically expressed this hitherto impenetrable region is that in size between the smallest wave length of light and the dimensions of a mole-crile.
The greatness of this achievement is readily understood when it is considered that while 250 years of effort were meeded to perfect the Optical microscope and attain a maximum linear magnification of 2,000, only six years were needed to [reach a linear magnification of 30,000 with the electronic microscope.
