MADRID, Spain (AP) _ Princess Maria Cristina de Borbon y Battemberg, an aunt of King Juan Carlos, died Monday of heart failure. She was 85.

She was the sister of Juan de Borbon, who ceded his rights to the Spanish throne in favor of his son, Juan Carlos.

Juan de Borbon's father, King Alfonso XIII, abdicated in 1931 upon the declaration of the Second Spanish Republic and the family went into exile during the 36-year dictatorship of Gen. Francisco Franco.

But Juan Carlos returned to Spain to be educated under Franco, and the dictator named him his successor. He became king two days after Franco's death on Nov. 20, 1975.

NEW YORK (AP) _ Newell Jenkins, a conductor and musicologist whose discoveries shed light on the Baroque, Classical and early Romantic repertories, died Saturday at age 81.

Jenkins' Clarion Concerts, a series he started in 1958, helped listeners discover hundreds of rare works gleaned from his visits to palace and monastery archives in Europe.

His specialty was Italian music, particularly that of Giovanni Battista Sammartini, Gaetano Brunetti and Simone Mayr. He also championed the music of Joseph Martin Kraus, an 18th-century Swedish court composer.

He was on the faculty of New York University from 1964 to 1974 and was a lecturer at the University of California, Irvine, from 1971 to 1979.

Dr. Joseph C. Muhler

FORT WAYNE, Ind. (AP) _ Dr. Joseph C. Muhler, a co-developer of Crest toothpaste credited with discovering that stannous fluoride could reduce tooth decay, died Tuesday. He was 73.

As a student at Indiana University dentistry school, Muhler studied fluoride and tooth decay at the suggestion of his biochemistry professor, Harry G. Day. Procter & Gamble began funding the research in 1949.

Muhler, a Fort Wayne native, and Day tested their new toothpaste with Bloomington public school students starting in 1951. Crest made its debut in 1956.

Royalties from the stannous fluoride patent were split between Muhler, Day and another scientist. They gave 50 percent _ $2.5 million _ to the Indiana University Foundation.

In 1967, the U.S. Navy awarded Muhler its highest civilian honor, the Navy Distinguished Public Service Award, for allowing the Navy to test and evaluate his discovery for free.

In 1992, the American Association of Botanical Gardens and Arboreta named Raulston's arboretum the best in the United States.

Ronnie Scott

LONDON (AP) _ Ronnie Scott, whose London club was a mecca for the world's leading jazz musicians, singers and fans, died Monday. He was 69

He began playing professionally at age 16, landing a job with the popular 1940s Ted Heath dance band.

After World War II, a shortage of shellac meant few jazz records were being released or imported in Britain, and the Musicians Union would not allow U.S. jazz musicians to perform in Britain.

Scott wanted to see the changing U.S. jazz scene and found a job playing in a band on the Queen Mary cruise liner, which sailed between Britain and the United States.

Scott opened Ronnie Scott's Club in a basement in central London's Soho district in 1959.

Inspired by the music of Charlie Parker and the New York bebop scene, Dizzie Gillespie and Thelonious Monk, Scott and his business partner Pete King turned the club into Britain's leading venue for modern jazz.
