Luxfer Prism Co.,
Rookery Building, City.
Replying to your favor, we beg to say we find
the Prisms all we anticipated, and the result has been to do away with
artificial light, except as to places in the office which are shielded
from its influence by wall and fixtures. By it, sunlight is carried
through to the farther wall and, the intensity of the light such, we
were obliged to subdue it at certain hours by shades. The effect upon
spirits of employes and customers, we believe, is marked, and we are
pleased to commend it in every way, believing it will add health to
satisfaction in our case.
