Petroleum oil additives—The oil solubility and color sta- bility of the Primene amines can be used to advantage. 2.

WASHINGTON SQUARE, PHILADELPHIA 5, PA. Representatives in principal foreign countries
Atomic Defense. A Senate subcommittee will conduct a full-scale probe of the nation's defense against possible atomic attack.
Tarif? Cuts. Gradual reduction of tariff barriers of all kinds should be considered in any long range foreign trade program, Charles R. Sligh, Jr., president of National Association of Manufacturers, recommends.
Latin American Trade. A joint Senate-House committee will visit Central and South America to determine how trade with U. S. could be increased.
USDA Reorganization. A proposed reorganization of the Department of Agriculture will see the Agricultural Research Administration pulled apart and recom-bined into several new divisions or branches along functional lines.
Foreign Aid. Increased military assistance raised foreign aid to over $7 billion in the year which ended last June 30. This is the highest amount since World War II. Military assistance accounted for $4.4 billion and economic and other aid, $2.6 billion.
Positive List. Cinchona bark has been added to the positive list and may not be exported without a license. Ammonium sulfate, p-nitroaniline, and plastic fabrics based on vinyl or vinylidene chloride resins or polymers, e.g., saran woven sheeting, have been removed from the positive list.
Se lec t ive Service. The Army has asked Selective Service System to provide 23,000 men for December. The Navy, Air Force, and Marine Corps have asked for no men for this period.
Government Security. Government employees who refuse to testify before Congressional committees regarding charges of alleged disloyalty or other misconduct on grounds of constitutional privilege against self-incrimination are now subject to dismissal from government service.
Navy Reorganization. An eight-man committee has been named to study organization of Navy Department. Elimination of any overlapping or duplicating functions and assurance that deficiencies and problems will be brought to attention of top-level staff will be principal objects of study. A report is due late this year.
Foreign Investments. American direct investments in Latin America totaled $5.7 billion at the end of 1952, double that of 1943, and $1 billion greater than at the end of 1950. Petroleum investments led all other types. Commerce Department also reports that, on a world-wide basis, about 2300 American companies and individuals have controlling interests in about 7500 foreign enterprises whose assets exceed $22 billion.
