In 1827, when Ashley-Cooper was appointed to the Select Committee on Pauper Lunatics in the County of Middlesex and on Lunatic Asylums, the majority of lunatics in London were kept in madhouses owned by Dr Warburton. The Committee examined many witnesses concerning one of his madhouses in Bethnal Green, called the White House. Ashley visited this on the Committee's behalf. The patients were chained up, slept naked on straw, and went to toilet in their beds. They were left chained from Saturday afternoon until Monday morning when they were cleared of the accumulated excrement. They were then washed down in freezing cold water and one towel was allotted to 160 people, with no soap. It was overcrowded and the meat provided was "that nasty thick hard muscle a dog could not eat". The White House had been described as "a mere place for dying" rather than curing the insane and when the Committee asked Dr MacMichael whether he believed that "in the lunatic asylums in the neighbourhood of London any curative process is going on with regard to pauper patients", he replied: "None at all".
