The mean, or most frequent, distance at which No. 1 was read, 

 was 19 inches, i.e. 7 inches in excess of the theoretical distance of 

 12 inches; while No. 10 was read at the exact theoretical distance of 

 10 feet. The average distance at which the boys read the smaller type was 

 18v inches, a deficiency of y;, of an inch for the whole school ; and the 

 average distance at which the larger type was read was 9 - 3 feet, or a loss 

 of / ?1 of a foot. The nineteen masters, between 20 and 40 years of age, 

 read both types at a greater average distance than the boys. The 

 average distance at which No. 1 was read increases at an almost uniform 

 rate of 1 inch for every two years up to 18 years of age. The sight of 

 the five masters, of the age of 40 and upwards, is probably exceptional, 

 and the number of observations are too few to be relied on. 



The following table is interesting as showing the relation which the 

 two tests bear to each other when applied to the same individuals. The 

 general disposition of the figures shows that the sight which is proved to 

 be good by one test is good also by the other test ; but there are some 

 notable exceptions to this rale, a few of which are probably due to errors
