children. At first I was doubtful about it, as I had not seen any of this work, but the more I studied it, the more I realized its value. Fortunately, if a thing is proved to be of value we can get the money for it. The next thing was to educate the superintendent and the board of education, of which I was the chairman. We had one of these instruments brought in one evening, with head pieces, so that all the members of the board could try it and see how it worked, and it showed some of them that they had one ear deteriorating and did not know it. Unfortunately, I have no statistics as to what resulted from its use, but it has brought to the atteniton of the school physician, school nurse, teachers and parents minor defects-minor degrees of deafness that they did not know about before.

Removing anything that is producing deafness in the early stages is better than to wait until Willie is so deaf that his mother has to tell him five times to do anything. We also have an excellent teacher of lip-reading who is doing good work in night school as well as with a few children.Dr. Frank H. Rodin, San Francisco : The San Francisco Board of Health has just completed a hearing survey, with the phonograph audiometer, of all school children from the fourth grade through junior high school. All told, 36,191 children were tested and on the retest 3,421 had a loss of 9 or more sensation units in one or both ears. This is 9.5 per cent of the children tested.

The ears were examined with an electric otoscope and an inspection of the mouth was made. Correctable defects were found as follows : 355 had large and infected tonsils; 185, discharging ears; 180, impacted cerumen in one ear; 114, impacted cerumen in both ears, and nineteen nose troubles. The total number of defects
