ON THE INFLUENCE OF SCHOOL-BOOKS UPON EYESIGHT. 307 
SUPPLEMENT. 
SPECIMENS -+OF TYPE. 
Tue Committee draws attention to the fact that 
there is considerable variation in the size of the 
faces of the various types coming under the same 
rating in point body, or bearing the same trade 
description. The following specimens afford satis- 
factory examples of existing types which conform 
with the dimensional rules proposed by the Com- 
mittee. For age-periods ‘seven to eight’ and ‘over 
twelve’ the smallest examples show the smallest 
sizes which the Committee regards as permissible. 
The specimens may usefully be compared by 
measurement with the specifications in the Typo- 
graphical Table.
