96 MODERN BIOLOGIC THERAPEUSIS 



of infection are the extremities, notably the 

 hands and feet. Many traumatisms such as 

 blank cartridge wounds and other Fourth-of- 

 July injuries, gun-shot wounds, nail punctures, 

 machinery wounds, crushes, and other injuries 

 in which dirt is carried into deep wounds 

 are more or less liable to be followed by tetanus. 

 The danger is especially great when the dirt 

 is ground into the injured tissues; street dust 

 and garden soil being particularly apt to con- 

 tain tetanus spores. 



Localities In many localities the danger is 

 much greater than in others. The sections of 

 the United States in which tetanus is most fre- 

 quent are northern New York along the Hudson 

 Valley, Brooklyn and the surrounding districts 

 of Long Island, southern Pennsylvania, Vir- 

 ginia, Georgia, Louisiana, Indiana, Illinois and 

 southern California. Where tetanus is preva- 

 lent, the horse manure is generally infected 

 as the tetanus bacilli grow in the intestines of 

 this animal and the spores remain alive in the 

 dirt for years.
