2. The second process which was worked out is the so-called Berka method. According to this method, the salts present in the sea-water are not precipitated, but are so treated that they are not disagreeable to the taste. They pass through the body without oversaturating it with salts and without causing an undue thirst. No special plants are necessary for producing preparations needed for this process; nor do the preparations themselves consist of scarce materials.
It can be presumed that this method will be introduced in the Luftwaffe and the navy in a short time. Now that German technical science has actually succeeded in rendering sea-water potable for people in distress at sea, in accordance with the above, the knowledge as to how foreign countries intend to solve this problem is no longer of prime importance. Naturally the office is very much interested in ascertaining how, above all, the United States has solved this problem, and it is requested that this information be sought, without, however, compromising any person or any office too much.
Should the office there be interested in the Berka method, let us know. Samples can then be delivered.
The cube dispensed is not a preparation to render sea-water potable, but a milk cube such as is already familiar to the offices.
