alone,  and  further  to  7’30  by  the  addition  of  quinine  prophylaxis.

These  striking  results  have  been  obtained  largely  by  means  of 
State  legislation.  A  series  of  laws  have  been  promulgated  giving 
the  public  the  right  to  buy  quinine  at  a  minimum  price,  imposing 
upon  employers  the  duty  of  preventing  the  damage  done  by  malaria 
by  giving  the  preventive  quinine  gratuitously  to  workers,  and  of 
compensating  them  by  giving  them  the  curative  quinine  gratuitously, 
and  giving  the  poor  the  right  to  have  quinine  given  them  gratuitously 
by  the  charitable  institutions.
