 The directions were written in very simple English so that they might 

 reach all types of unindoctrinated individuals. 



The following are the printed directions as stamped on the proc- 

 essing bag : 



1. Screw plug in outlet tube at bottom and fill bag to line with sea water. 



2. Add briquet. Tightly roll top of bag down toward buckle and strap securely. 



3. Allow briquet to stand in contact with water for a few minutes. Then 

 gently knead bag with hand for 10 minutes until entire briquet is broken into a 

 fine powder. 



4. Shake bag occasionally for at least 20 minutes more, so that desalting 

 material is kept in thorough contact with the water. 



5. Now suck clear filtered drinking water through drinking tube. 



6. After sucking out all water, rinse bag in sea water to remove used-up 

 desalting material. 



These developments have led to the adoption of the Naval Medical 

 Institute modification of the Permutit method by the Naval Bureau 

 of Aeronautics, the Army Aviation Corps, and various private air- 

 lines operating with the Army and Navy, and it is now being con- 

 sidered by the War Shipping Administration for possible use on 

 transports and freighters.
