Australia celebrated one hundred years as a nation in 2001. This book - part history, part travelogue, part memoir - tells the inspiring story of how a one-time British colony of convicts turned itself into a prosperous and confident country. Through the eyes of ordinary people, Phillip Knightley describes Australia's journey, from federation and the trauma of the First World War, the desperate poverty of the Depression, with its attendant spectres of secret armies and near-civil war, the threat of invasion in the Second World War and the immigration that followed it, and the slow but steady decline in the relationship with Britain, the 'Mother Country', as Australia forged its own unique identity.

This book presents a wide-ranging introduction to the diatoms together with an illustrated description of over 250 genera. Diatoms are important as perhaps the commonest group of autotrophic plants on earth and are abundant in all waters and on soils and moist surfaces. The introduction describes the diatom cell in detail, the structure of the wall (often extremely beautiful in design), the cell contents and aspects of life cycle and cell division. The generic atlas section is the first account of diatom systematics since 1928 (Karsten in Engler and Prantl: Die Nauturlichen Pflanzenfamilien) and each generic description is accompanied by scanning electron micrographs to show the characteristic structure. Most of the latter have been prepared specially for this work from the authors' own collections. The Diatoms will be the standard reference work on the group for years to come and is an essential reference volume.
