502, and a fourth school in a representative well-to-do district of the city. It was impossible for us to go over the cards for all the children of those four schools, so we decided to take as many cards as we could get for one class of each grade of the schools in question, endeavoring in this way to bring into the study children of all ages in each school. In all we have examined 1,452 records. From these closed records for the first term of 1912-1913 we have tabulated the number of children suffering from physical defects, but have not included cases of contagious diseases or communicable diseases of the eye and skin, as they are being treated in schools, so that our inquiry referred only to cases of defective vision, defective hearing; defective teeth, primary and permanent; defective nasal breathing; enlarged tonsils; defective nutrition; cardiac, nervous and pulmonary diseases; and orthopedic defects.

There were 1,617 cases of these defects alone noted for the 1,452 children whose records were examined. Bad teeth constituted two thirds of the defects. While the per cent, of all the defective children found among those investigated in the four schools, exclusive of bad teeth, was 41, it varied from school to school. It was 40 per cent, on the lower east side, 54 per cent, on the east side in the neighborhood of 30th Street; 21 per cent, in the well-to-do uptown district, and 50 per cent, on the upper east side near 103d Street. Of all the defects, bad teeth were most poorly attended to. In the school in the foreign district of the city where cooperation of the school with the medical corps was very good, 90 per cent, of the cases of defective permanent teeth were treated, but none of the 147 children with carious milk teeth received any treatment. In the school where cooperation was poor, 28 per cent, of cases with defective permanent teeth were treated and no primary teeth defects were reported remedied. In the school in the well-to-do section of the city, 56 per cent, of cases of bad permanent teeth were treated and 17 per cent, of bad primary teeth. For the school near the dispensary, 35 per cent, of bad permanent teeth is reported as treated, and out of the 239 cases of primary bad teeth only 1 is reported as having been treated. As to other defects the cooperating school reported 94 per cent, of children with defects receiving treatment as against 65 per cent, for the school whose attitude was antagonistic to the Department of Health. The well-to-do section school reported 80 per cent, of its defective children under treatment, and the school near the dispensary reported 86 per cent, under treatment. If the teeth defects be counted in, then the per cent, of treatments for all the defects, other than communicable eye and skin diseases, will respectively be: 47 per cent., 32 per cent., 54 per cent, and 41 per cent. As to individual defects, the following table shows the per cent, of treatment in the case of four chief classes of defects:
