PHYSICAL EXAMINATIONS 



ratio, there are 32 possible combinations of five defects, and 64 

 of six defects. 



These figures will suffice to support the statement that any 

 plan for recording combinations of defects must provide for 

 recording data pertaining only to the more important sorts of 

 defectiveness. Fortunately, this is made possible by existing 

 conditions. We have seen from the data presented that defects 

 of teeth, eyes, throat, and nose constitute more than four-fifths 

 of all the cases of physical defectiveness. 



The problem, then, is to develop a system for recording 

 the combinations of these defects. This can be done simply and 

 easily by making provision on the individual physical record card 

 of each child for recording the presence of any of these defects 

 or any combination of them by printing the four words Teeth, 

 Throat, Eyes, Nose, at the four corners of a square as follows: 



Teeth Throat 



Eyes Nose 



If the examination shows that the child has defective 

 teeth, the fact is recorded by drawing a line from the word 

 "Teeth" to the dot in the middle of the square as follows: 



Teeth. Throat 



Eyes Nose 



In a similar way this device may be used to record any one 

 of the 1 6 possible combinations of the four defects. These possible 

 uses are the following: 



No Defect One Possible Combination 

 Teeth Throat 



Eyes Nose
