CHARLES S. FROST, Architect.

1127 Rookery, City.
Gentlemen:
Replying to your request for a letter for
publication, as to my opinion of your product, I am pleased to state
that I have been familiar with the same for the past year, and have
observed carefully a great deal of it in actual use, and have noted
the very satisfactory results, and have also specified and used a
large quantity in my work.
The results are as you claim. The work,
especially of your Iridian product, is more artistic than I thought
you could ever make it, and is certainly very satisfactory in the Home
Insurance and Watson's buildings, and the banking room of the Northern
Trust Company, from both inside and outside.
I can easily see how smaller courts inside may
be omitted, and how larger light courts can be very much reduced in
same by the introduction of your product; also that it is practically
to the interest of architects and owners to use this product whenever
artificial lights would be required.
I take great pleasure in commending the use of
it to other architects.
Yours very truly,
SAMUEL A. TREAT.

Gentlemen:
The advantages gained by the use of the "Luxfer
Prism" for transmitting light to darkened places in buildings have been
sufficiently demonstrated in this and other cities.
When there are so many instances constantly open
to inspection, I can hardly hope to remove a doubt by a letter of
commendation.
Let any person who hesitates in using it, visit
the intersection of La Salle and Adams streets, and if the display of
"Luxfer Prisms" is not bewildering, he may step inside and be convinced
that it serves the purpose in a most satisfactory manner.
Yours truly,
F. N. MATTHEWS & CO.

Dear Sirs:
The two lights which you placed over our fitting
room windows have much increased the light within, and we are very much
pleased with the result.
Very truly,
