Protection of Wounds. All wounded surfaces should be 

 covered with some protective material in order to prevent 

 diseases from gaining an entrance. No artificial material 

 will aid in healing of any wound, but it prevents water and 

 other foreign material from entering. 



Small wounds not to exceed one-half to three-quarters of 

 an inch will usually heal over in one year and no covering is 

 necessary. Larger wounds, however, should be protected. 

 White lead paint, which is of the consistency of thick cream, 

 is perhaps the best material to use for wound dressing. 

 It is easily secured, it adheres well, it does not crack or 

 chip off, it is easily applied and does not interfere with the 

 healing process. Occasionally tar products and grafting 

 waxes are also used.
