Alumni members of Skull and Bones voted to admit women into their secret society at Yale University, rejecting the fierce efforts of opponents to keep the 159-year-old club all-male.

A Bonesman, speaking on the condition of anonymity, said about 55 percent of the society's members voted Thursday night in favor of admitting women.The move clears the way for the initiation of six women students into the organization that counts among its members some of the nation's most powerful men, including President Bush.

Each year the group asks 15 Yale juniors to join. Those approached in May included the six women.
