The usual procedure was followed of testing with Snellen's
Test Type at 20 feet, and all the testing was done by the same
nurse, who has been doing the work for years, and is very
accurate. Also from time to time I retested children and our results
al.vays agreed, so that I have no hesitation in accepting
her figures.
The number of children examined whose vision was marked
as requiring no treatment was 405. The ages varied from 5—13.
The accompanying tables show the results obtained.

NOTE.—For the purpose of calculating the difference in vision in
the above table, all partly read lines are counted as the line
above, e.g. 6/6p is recorded as 6/9, and in cases where the
vision is different in each eye the worse vision has been taken.
