A guide to correct forms of address in speech and correspondence. It covers both formal and social occasions, and includes the forms of address for bishops, peers, privy counsellors, ambassadors, JPs and mayors. Where honours, decorations and degrees appear after the name as letters, an explanation and the correct sequence is given. This edition is revised and updated to cover changing conventions. Now in its 23rd edition, this book has been in constant demand for over 90 years.
