Corrections

In the last issue, we mangled the name of the late Prof. Fred D. Ayres [chemistry 1940–70], mistakenly dubbing him Frederick. His widow, Prof. Angela Ayres [Spanish 1966–73], was kind enough to remind us that his name was indeed Fred, pure and simple and in need of no ornament. We made the same mistake in December 2011. We’re sorry for the errors.
