Commissioner Lamb surveys, from the extensive experience of fifty years' remedial and ameliorative work in the Salvation Army, the changes the last half-century has seen in the conditions of working-class life in this country. Particular interest is given to this review at the moment by the publication of the third volume of the ' New Survey of London Life.' This continues the work of ! Life and Labour of the People of London ' published between 1891 and 1903 by Charles Booth , the sociologist, called the ' particular,' to distinguish him from William Booth , the ' general.'
