ONOX, Inc., San Francisco tin: never yet has a test been reported to me where Onox failed to make a better showing than all other competitors. Several years ago Dr. Gudakunst of Detroit made a test in six different schools of six different products and reported Onox at the head of the lists "With a remarkable decrease in the incidence of infection". I hope you will excuse this long letter and bringing you into the matter but believe you will feel that in the in- terest of fair play we should be entitled to a report. Wouldn't you feel that way if in my place. Very truly yours, ONOX, Inc. By
