Macmillan Dictionary of Life Sciences [antikvár]

Preface to the Second Edition This dictionary was first pubhshed in 1976. Its success, in schools and universities both at home and abroad, has provided the stimulus to update and expand it In this new edition we have increased the text by some 300 new entries, most of which reflect recent advances in genetics, molecular biology, microbiology, and immunology. Existing entries that relate to these topics have been revised and updated. There has been a small reduction in the coverage of the more traditional aspects of biology. This reflects the shift in emphasis in biology teaching away from classical zoology and botany and enables the new material to be accommodated without making the book considerably larger and therefore more expensive. I should like to thank Drs Maclean, McCready, and Wratten for their help in preparing this new edition.
