While researching lunatic asylums I came across the Science Museum’s ‘Brought to Life’ web feature on mental health:
This is one of 16 sections covering different aspects of the history of medicine. Others which are relevant to the Medical History of British India are Public Health, Hospitals and Diseases and Epidemics.
The website is a Science Museum and Wellcome Trust collaboration and features photographs from the Museum’s collection. It is well worth a look.
