[Illustration] [Illustration] BANNER'S SYSTEM OF HOUSE DRAINAGE AND SANITATION. BANNER'S PATENT VENTILATING COWL. _No House having a Water Closet in it should be without one fixed on the Soil Pipe carried above the Roof, and for the Ventilation of Public Buildings and Rooms they surpass any Ventilator yet introduced._ OPINIONS OF THE PRESS, Etc. "Ventilate! Ventilate! Ventilate!"—PUBLIC HEALTH. "The word 'impossible' has ceased to exist in the vocabulary of the sanitary reformer; if a prevalent evil ought to be removed, it can be removed."—TIMES. "The system devised by Mr. Banner is as near perfection as may be: nothing better need be desired. By means of this simple apparatus the _foul air_ in _any shaft_ will be continuously extracted."—SANITARY RECORD. "We believe Mr. Banner's system of sanitation will make any house absolutely safe from sewer gas or noxious odours of any description from the drains or closets."—ARCHITECT. "One lesson which Mr. Banner has learned, namely, that to make a ventilating-pipe of constant avail air must be introduced at the bottom, is of itself a boon of value."—THE BUILDER. "A thorough current of air is constantly maintained by an inlet placed just above the trap, and an outlet above the roof, to which is annexed the cowl, preventing any downdraught. A velocity of 510 feet per minute was registered by an anemometer under very ordinary circumstances."—BUILDING NEWS. "The conclusion I have come to after a considerable time spent upon their study is, that Banner's Sanitary Appliances are the best media extant for the work which they are intended to compass, that I can confidently recommend them, and that they ought to be specified by architects generally."—WM. EASSIE, C.E., author of "Sanitary Arrangements for Dwellings." "Mr. Banner's system thoroughly effects what it proposes—namely, to render houses wholesome which are now mere deadly fever-traps, whether they be mansions in Belgravia or cottages in the suburbs."—JOHN P. SEDDON, F.R.I.B.A. "Mr. Banner's system fulfils all the conditions specified in the contract. There is no foul air generated. The several currents in the soil-pipe, in the drain, and in the large sewers—a channel of 350 feet in length—have uniformly been found to be flowing in the right direction whenever they have been tested; and this has been done repeatedly."—GUY'S HOSPITAL GAZETTE. "I believe in your cowls, and I think that probably I am as impartial a judge as can be had, yet I candidly confess that if I knew of a better cowl I would most certainly employ it."—H. H. COLLINS, F.R.I.B.A.
