A brief on yesterday's Science page stated incorrectly that farmers already inject pigs with a naturally occurring hormone to make the animals grow bigger and faster. Researchers are investigating ways to artificially boost the growth rate and size of farm pigs.

In an article Sunday about the campaigns of Vice President Gore and Bill Bradley, scholars Cornel West, whose name was misspelled, and Henry Louis Gates Jr. were identified with the wrong university. Both are at Harvard.

A news brief on Saturday's Religion page incorrectly quoted the Dalai Lama, who gave the closing address Wednesday at the Parliament of World Religions in Cape Town, South Africa. The quote should have read: "Changes only take place through action--not through prayer, not through meditation."

In the Health section's Second Opinion column last Tuesday, Dan Collison's name was misspelled. Collison was a producer, director and photographer for the film "Scenes From a Transplant: A Cancer Diary."

A photo caption Dec. 1 incorrectly described an accident on Frederick Road in Rockville. According to a police report, a 1991 Buick Park Avenue attempting a left turn from Redland Road failed to yield the right of way to a 1998 Mack truck. The truck collided with the Buick and ended up on its side. The force of the collision sent the Buick into a 1999 GMC Safari, which was attempting to make a left turn. The truck did not turn over on top of the two vehicles.

CLARIFICATION

A quote from the Biotechnology Industry Organization that ran in large type in an article Saturday about the release of information about gene therapy experiments incorrectly combined words from two sentences in the organization's statement. It should have said that the organization stated that data about "adverse events . . . are, by definition, trade secrets and confidential commercial information."
