MEDICAL INSPECTION OF SCHOOLS 



of health. If they have been taken sick with any of these infec- 

 tious diseases in the school room, the pupils of the room are dis- 

 missed and the room disinfected. 



In the accompanying tables figures are presented showing 

 the number of exclusions for each of the more important diseases 

 in four cities. In Table 7 the figures are the original data 

 taken from the latest available reports. In Table 8 the 

 figures are relative, showing the number of exclusions for each 

 disease among each thousand children excluded. They indicate 

 the variations which are encountered in this work. These varia- 

 tions exist not only between cities but between different years in 

 the same city, and are mostly due to the fluctuations caused by 

 local epidemics. The commonest disorder, and the one causing 

 the largest number of exclusions, is pediculosis.

Further data showing the great variations between cities 

 in the matter of exclusions are presented in Table 9, which 

 compares the number of exclusions with the total school mem- 

 bership in eight cities. The figures for exclusions are taken
