In the quest for an ideal ear drop for the common chronic otorrhea, the gamut of chemical agents has been tried, from the time-honored boric acid-alcohol solution to the sulfonamides, glycerite of hydrogen peroxide and the antibiotics. Although each one gives a certain degree of clinical satisfaction, there is still room left for improvement. The literature on the subject is so voluminous that one is at a loss concerning the merit of one chemical over that of the other.
