Curiosities In Laboratories Become Vital

Of the hundred-odd chemical elements which exist in the earth's crust about eighty are classed as metals. But by and large industry uses only about a dozen metals-iron, copper, aluminium, tin and zinc are ones that leap to the mind.

In recent years, however, more and more attention has been paid to the "new" metals. Although many of these have unusual names and may not be widely known, most of them have been known as laboratory curiosities for many scores of years.

But they are still new in the and therefore increase the

Outstanding Advance In High-Quality Sound Reproduction

A new loudspeaker system which embodies entirely new design principles and represents an butstanding advance in high-quality sound reproduction has been developed at the Research Laboratories of The General Electric Co. Ltd.

The system has been called the "periphonic" loudspeaker

system. It exploits fully the
