of observation. The table also shows the difficulty, already referred to, of 

 drawing the line between good and imperfect eyesight. Judging from 

 the value of the groups of figures, I have separated the boys whose sight 

 with No. 1 falls short of 12 iuches, and with No. 10 of 7 feet, as possess-

 respectively. Thus 83'3 per cent, of the boys possess y 7 ^ and upwards 

 far sight, and 91"8 per cent, possess \f and upwards of normal near 

 vision. Sight which with both tests falls within the central square of the 

 following table may be deemed good for all the ordinary purposes of life. 

 Astigmatism. — Tested by letters constructed of horizontal and vertical 

 lines, 60'3 per cent, of the Marlborough College boys were found to be

 the defect. The following figures show that there is a disposition for
