American Luxfer Prism Co.,
|Chicago, August 17, 1897.|
1127 Rookery, Chicago.
Replying to your inquiry as to how I like the
Luxfer Prisms, which you installed in the flat which I am now renting
at No. 180 Dearborn avenue, I would say that we were both pleased and
surprised at the results which you obtained. The dining room, which
before was dark and gloomy, is now bright and cheerful, and we now
have daylight an hour or two longer both morning and evening, and have
not had our gas lit since the Prisms were installed, although we have
had several cloudy days. The light shaft in which these Prisms were
set is only four feet wide, and we did not suppose it was possible to
accomplish the results which you have, and heartily recommend your
Prisms to any one situated as we are.
