This book is intended to be used as a working textbook, with spacing left after each section for students to make their own notes. The text and diagrams have been produced in such a way as to keep a specialist subject within the budget of cost-conscious students. It is the contents themselves which are of importance, especially the illustrations which bring out the essence of the text in a way which words alone could not achieve.
