WORLD ACHIEVEMENT
THE NEW MIRRORS. Mirrors have long been valued arl iclcs. They wore used t lioi'tsa lids of years ago, ilie Creeks deliyilil ing in hand niirroi's with handles in the shape ol {roils or goddesses. Ii is helicveil that <‘\’<‘ll the ancient Britons had metal refine 1 ors on their chariots so that the charioteer might see ivhnt u;t-s behind him without turning his head—a kind of Forerunner of the motorist's mirror of to-dav.
.Vow. we hear, our clever inventor.have discovered that mirrors are mort efficient if they are hacked with golc instead of silver.
A silvered mirror gives a wonderlu! reflection, hut a mirror with a thin film of gold at the hack is still more wonderful. During Itk'iti Professor Charles Gibson, of (toy's Hospital discovered a method of depositing ex tremely fine films of gold on glass some of them only .0001 of a millimetre thick. ISv this means a remarkable transparency is achieved, the mirrors having a rare greenish hlue eolnur. In reflected 1 ■«rht they apopar to he of massive gold. There is no need lo polish the stir face. The gold is so line and smooth and the extreme “finish" makes them tar superior to anything made in the usual fashion. What is more, a mirror six inches in diameter and coated with gold film costs less than one hacked with silver —the total value of the gold used being only one-eighth of a ponnv. All this is food for reflection.—(h.)
