In 1937 the American Medical Association resumed its annual summaries of injuries resulting from the celebration of the Fourth of July with fireworks.1 As pointed out in that report, the considerable increase in the number of such injuries made it expedient to renew the annual reviews.
In 1938 there were eighteen deaths reported as directly due to the celebration of the Fourth of July with fireworks and other explosives and seven additional deaths indirectly due to the same cause. The distribution by states is given in table 1. It may be noted that in 1938 Pennsylvania led all other states with six deaths from fireworks and two additional deaths attributable indirectly to this cause.There were two main causes of death: the body burns suffered by little girls when their flimsy dresses caught on fire from sparklers or firecrackers, and the mutilations received by boys
