An obituary in the Sunday editions of The Washington Post on John Gallup Laylin, 76, who died Friday, incorrectly stated the organization to which expressions of sympathy could be sent. They may be sent to Deep Springs College in Deep Springs, Calif.

John Gallup Laylin, 76, a senior partner with the Washington law firm of Covington & Burling, died Friday at Fairfax Hospital after he was injured by a falling tree branch on his farm in Great Falls, Va.

Mr. Laylin served as special assistant to the undersecretary of the Treasury from 1933 to 1935, and helped draft the gold clause resolution that was adopted by Congress and took the United States off the gold standard.

After leaving the Treasury, he joined Covington & Burling and specialized in international law. During 1940 and early 1941, he advised governments in exile, including the Netherlands and Czechoslovakia, on protecting their citizens' property in this country from being seized by the German government.

During the late 1940s, he did legal work for the Iranian government, which won a case in the U.N. Security Council that helped lead to an end of Soviet wartime occupation of northern Iran.

Mr. Laylin also negotiated the Indus Waters Treaty of 1960 between India and Pakistan. He had worked as an adviser on fiscal matters to a number of foreign governments, and was a member of the State Department's advisory committee on the law of the sea.

He was a principal founder of the Washington Institute of Foreign Affairs and president of the Telluride Association from 1927 to 1928.

Mr. Laylin was a native of Norwalk, Ohio. A 1925 graduate of Cornell University, where he was elected to Phi Beta Kappa, he earned a law degree at Harvard University.

Early in his career, he worked as a special assistant to U.S. ambassador to Mexico Dwight Morrow, and for the law firm of Sullivan & Cromwell in New York.

Mr. Laylin belonged to the Metropolitan and the 1925 F Street clubs in Washington and the Century Club in New York City.

He is survived by his wife, the former Diana S. Morgan, of the home; two sons, John G. Jr., of Ferndale, Wash., and David L., of Tehran, Iran; two daughters, Laura, of West Newton, Mass., and Princess Louise Firouz, of Tehran; a sister, Ruth MacDonald, of Norwalk, and 11 grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to Hidden Springs College, Hidden Springs, Calif.
