WASHINGTON, Oct. l.--Prof. Elmer Gatea,
who has come into prominence by reason of his
recent successful experiments in the field of
microscopy, has a large and well-equipped lab
oratory ut Chevy Chase. near Washington.
1t is the largest psychological laboratory in tho
world. \ scientific paradise. so TO speak. ,
where the elect may revel in apparatus'of most
intricate and unpronounccable nomenclature.
Here his experiments have been carried on for
several years, some of his studies having been
begun twenty-five years ago. His latest
achievement is an instrument that magnihes
800 times more than the present microscope.
thus opening up n world as new to science as the
one that was developed by the original micro
scope, which magnit!cs 1000, diamctcrs.
