PREVENTION OF DISEASE 
to prevent it. A great deal of progress has been made and 
some states are far in advance of others in prevention of 
disease. We have really made only a beginning in this 
direction and by the time that you have become men and 
women many additional measures will be in operation to 
assist you and your children in keeping well. Reference 
has already been made on page 513 to some of the efforts 
that are being made in New York State to save infants 
from dying of preventable diseases. This is known as the 
Child Welfare Movement. What can you find out about 
this movement in your community? In this connection 
you should know about the work of the city or county 
bacteriologist and the health officer. 
The following notes were taken from the annual report 
of one of our New; York State cities: In the bacteriological 
office 10,872 diphtheria cultures were made; 399 examina¬ 
tions of blood, and 1293 cultures of the sputum of patients 
with suspected tuberculosis; 3073 chemical and bacterio¬ 
logical analyses were made of milk and 215 of cream. The 
drinking water of this city received repeated study, as the 
630 tests for bacilli coli indicates. There were 176 inocula¬ 
tions for typhoid and 973 miscellaneous studies. This does 
not include the work done by the division which has charge 
of vaccination against smallpox. Not only were the dairies 
near the city inspected but the more distant dairies were 
regularly examined. 
Closely associated with this technical work in the bac¬ 
teriology office was the work of the visiting nurse and 
the school doctor. In this same city nurses visited 3299 
homes during the year, and one school doctor made 2477 
physical examinations. He found 1845 cases of decayed 
teeth, 25 cases of poor eyes, and 36 cases of bad tonsils 
and adenoids. 
But the health of the city is cared for not only by looking' 
after the school children but also by inspecting food, and
