In army barracks each soldier is allowed 600 cubic feet.

Professor Huxley, at one time himself a medical officer in East London, always held that each person should have 800 cubic feet of space, and that it should be well ventilated with pure air.

Yet in London there are 900,000 people living in less than the 400 cubic feet prescribed by the law.
Mr.Charles Booth, who engaged in a systematic work of years in charting and classifying the toiling city population, estimates that there are 1,800,000 people in London who are _poor_ and _very poor_.

It is of interest to mark what he terms poor.

By _poor_ he means families which have a total weekly income of from eighteen to twenty-one shillings.
