John Playfair (1748 1819) was a Scottish mathematician and geologist best known for his defence of James Hutton's geological theories. He attended the University of St Andrews, completing his theological studies in 1770. In 1785 he was appointed joint Professor of Mathematics at the University of Edinburgh, and in 1805 he was elected Professor of Natural Philosophy. A Fellow of the Royal Society, he was acquainted with continental scientific developments, and was a prolific writer of scientific articles in the Transactions of the Royal Society of Edinburgh and the Edinburgh Review. This four-volume edition of his works was published in 1822. Volume 1 includes a biography of Playfair, and his Illustrations of the Huttonian Theory of the Earth, which did much to popularise Hutton's ideas.

James Hutton (1726-1797) was an eminent Scottish scientist known chiefly for his work in geology. Educated at Edinburgh University, Hutton then travelled to Europe to study medicine before going into industry. He spent over a decade farming his family property in Scotland before returning to academic and commercial life. Hutton became an established geologist who also published on chemistry, meteorology and philosophy as an active member of the Edinburgh Royal Society. This volume, first published in 1805, is a detailed and affectionate chronicle of Hutton's life by his close friend, geologist and mathematician John Playfair. The author recounts Hutton's academic career, speculates on the motivation behind his foray into farming and includes a detailed discussion of his main geological theories. With little of Hutton's correspondence and papers surviving, this account by an intimate contemporary is the key resource for studying the life of an intriguing figure in scientific history.

In 1785 he was appointed joint Professor of Mathematics at the University of Edinburgh, and in 1805 he was elected Professor of Natural Philosophy. This highly influential book, first published in 1802, contains Playfair's clarification and summary of Hutton's geological concepts. Playfair concisely explains Hutton's theories on erosion and geothermal heat in rock formation and the concept of uniformitarianism in geology, illustrating these theories with his own precise observations on different types of rock strata. The clarity of Playfair's explanations was instrumental in popularising Hutton's geological theories, many of which are now recognised as key principles of modern geology. Playfair's strident defence of Hutton's ideas formed part of a controversial debate between Hutton's supporters and his detractors.

Our immune system is a complex network of cells continually battling against a barrage of attacks from our environment, quite literally to save our lives. But what protects us from the potentially life-threatening microorganisms that surround us every day? In the lucid, accessible style for which John Playfair is renowned, and together with Greg Bancroft, an expert in infectious diseases, Infection and Immunity explains how our immune system defends us. The authors describe the main causes of infection that our bodies have to battle against - from bacteria to viruses, fungi to protozoa - and explains the intricate and fascinating ways in which we respond, from detection of potentially dangerous organisms to their ultimate elimination - sometimes, unfortunately, suffering new pathological symptoms in the process. Presenting a fully-rounded, well-balanced overview of the field, the book also explains how diseases spread, and what measures we can take to control this spread - from vaccination to increasing awareness through public health initiatives. With examples of infectious diseases from across the world, Infection and Immunity is the ideal text for biomedical science, bioscience, and microbiology students who need to understand the basics of what causes infection, and how our immune systems respond.
