Attention: Mr. W. Arthur Robotham

Gentlemen:

In reference to your cable, we have shipped you six filters and six extra cartridges. These filters are of the new improved design and we think that you will like this design much better than the old type. The cartridges sent you are of the same construction and are known as the number four cartridge. We have found this type to give the best results in operation in this country.

We will be interested to hear any comments you might have on these filters. Also in furnishing any more that you might require for testing purposes.

Yours very truly,

A.D. Redner
General Filters, Inc.
