The use ofglass is, of course, always a source of danger since it is liable tobreak. There is also a great variety in the design of sterilizationtowers. In general, however, the ozone is introduced at the bottomof the tower, which is filled with stone or sand, while the waterpasses downwards and thus comes into contact with the rising streamof ozonized air. A patent granted on February 9 to Mr. A. J. Wessels, of , relates to an ozonizet which is similar in design to that ofTindal. As shown in the adjoining illustration, a semi-cylindricaltrough of metal, which forms one electrode, is placed inside a jacketof enamel. The intermediate space is filled with water for coolingpurposes, since the process of ozonizing air requires that the tern-. i>;<^^xV////^/.iVx^y/^^^^^ WESSELS OZONIZER. perature should not rise above a certain point. A glass cover formsthe top of the apparatus and supports a series of metallic points, asshown in the illustration. The electric discharges take place betweenthese points and the semi-cylindrical metallic trough below. Thestream of air to be ozonized passes in a direction perpendicular tothe cross-section shown in the illustration. The air is passed suc-cessively through several ozonizers. between which special coolingdevices are inserted to reduce the temperature of the ozonized goes from one ozonizer to the next one.

Nothing is said concerning the electrodes to be used norconcerning the chemistry of the process, but it appears that likeother inventors he intends to use anodes of such a nature that theanodic p
