288 REPORTS ON THE STATE OF SCIENCE.—IQI13. 
type is being used largely even for literary works in 
Germany, the use of the less legible German types 
may be reduced in our schools with some gain to 
the security of eyesight. 
Conclusion. 
The Committee observes in conclusion that :— 
(1) The existence of a very serious amount of 
visual defect among children of school age is 
established as a result of official inspection. Some 
portion of this defect is preventable by greater care 
in the selection of books. 
(2) It is desirable that a standard of book- 
production should be established, and that the 
publication of books below standard should cease. 
(3) It appears possible that the adoption by 
local education authorities of a common standard 
would render unprofitable the publication of books 
which failed to reach such standard. 
(4) It is hoped that this report may assist the 
responsible authorities in the work of determining 
the standard of book-production requisite for the 
protection of the eyesight of children so far as it is 
influenced by the books which the children are 
compelled to read in school.
