SHADING INCANDESCENT LIGHT.
Mr William Sugg, speaking on "Artificial Gas Illumination in Relation to Natural Light," before the Institution of Gas Engineers on June 9, drew attention to the danger to the eyes by increasing the power of light without taking means to guard them from the effects of rays which were known to be deleterious.

Shades of rose colour or green should be employed in all cases ■where intense light is used.
