then giving way to numbness. The skin over the part may be 

 white or little changed. If permanently damaged, the part will 

 eventually turn black, the surrounding area swelling enormously, 

 and the skin becoming a mass of large blood blisters. Above all 

 else, the person should be placed in a shelter as soon as possible. 

 The injured part is then warmed slowly and kept at room tem- 

 perature (65° F. to 70° F.) with the remainder of the body made 

 as warm as possible with blankets and stimulating hot drinks. 

 Medical attention should be sought, if available. The pain may 

 be controlled by further cooling and the administration of half of 

 a morphine syrette every 4 hours, if available.
