Many thanks to error spotters, including Nicholas Bland, L. Molinari, Janet Peacock, Jan Poloniecki, Paul Pynsent, and Valerie Seagroatt.


Any text-book gets out of date. This is the only amendment which I thought would be needed before I produced the third edition.

Page 32: delete comments about ethics committees. In the UK, the new Multi-centre Research Ethics Committees will remove this problem -- we hope.
