of oiBcers that caused this. The law was specific in providing 

 that the space for each soldier should be from 400 to 500 cubic 

 feet in temperate climates, and from 480 to ()00 in the tropical 

 climates. The commissioners recommend 600 feet, in all cases, 

 per man, which is not a liberal supply, when the prisoner at 

 Dentonville has 900 cubic feet. 



It appears from a recent return, by Dr. Balfour, that the least ave- 

 rage space for each patient, in the London hospitals, is 800 cubic 

 feet. 



As to the effects of over-crowding, of having too little air to 

 breathe, the height of the parallelograms on the left table repre- 

 sents a height of ten feet and a depth of one foot, so that the 

 areas correspond very nearly with the centre spaces and repre- 

 sent them clearly to the eye. 



In the Black Hole, Calcutta, 146 persons shut up with twenty 

 cul)ic feet of air each, one-third died in two hours, and only 

 twenty-three survived after ten hours. 



The Union Workhouse, Peckham, had the paupers farmed out. 

 This municipal Black Hole was a shed of seven feet pitch in the 

 centre and two feet at the sides, of such dimensions as to sive 

 from thirty to sixty cubic feet of air to each one. It is said to 

 have held from 90 to 100 men when full; it was a fever factory, 

 and sent 130 patients to hospital, in London, in one year. 



In Church Lane, St. Giles, a number of rooms were found so 

 crowded that the space for each person was from ninety-three down 

 to fifty-two feet. One hundred and thirty-nine persons were under 

 treatment by the Workhouse staff — eighty-eight with fever. 



In one month the cholera carried off" twenty-nine from this 

 place, while -within a stone's throw of the same place, in the 

 Model lodging house, George street, occupied by 100 inmates, 

 only one died during the same time. 



In a house in Dorsetshire, as described in the Chronicle, the 

 cubic space allowed each inmate was eighty-four feet. Four out 

 of twelve died with fever. 



In one of the parish houses, in Lancaston, where the mortality 

 was very great, 100 feet of space was allotted to each. 



In Dronet's establishment for pauper children, at Footing, each 

 child had 136 cubic feet of air-space, and 170 deaths occurred in 

 three weeks. 



In the town Buderack, of Cambridge, 170 feet of space was 

 allotted to each inmate, who were attacked with gaol fever.
