sterilisation programme. These movements were often justified by complex calculations arising from novel concepts, such as Darwinian biology and Mendelian genetics. A great strength of this book is the range of sources that were consulted during its research. The author draws on data from the US, Norway, Germany, France and the UK. This allows a unique, global perspective on attitudes towards mental health during this period. It also illustrates the difficulties of those attempting to draw together data from different sources. This new, globalised medicine seemed to present as many challenges as it solved. Porter does well to make sense of global dialogue and to consider the effects of conflicts on the battle against mental ill health. Genetics in the Madhouse has the power to inspire, to captivate and to stimulate further research. Many that read this book may want to visit their local records office, to see how the trends that Professor Porter describes played out in their area. Others may be interested in the comparison between the late modern period and the contemporary era of psychiatry. There are now a whole range of treatments that were not available to Hagen, Lunier and contemporaries. This begs the question, therefore, of why recorded mental illness appears to have increased during the last 100 years. Perhaps there is still something that can be learned from the likes of Hagen with regard to understanding those that may be suffering from such conditions. Nicholas P.
