"'I met with very few colliers above forty years of age, who, if they had not a confirmed asthmatic disease, were not suffering from difficult breathing.'—_Fellows, Report_, s. 57; App. pt. ii. p. 256. "Phœbe Gilbert, Watnall, Messrs. Barber and Walker: 'She thinks they are much subject to asthma. Her first husband, who died aged 57, was unable to work for seven years on that account.'—_Fellows, Evidence_, No. 105; App. pt. ii. p. 256. "William Wardle, collier, forty years of age, Eastwood: 'There are some who are asthmatical, and many go double.'—Ibid. No. 84, p. 287, 1. 40. "Mr. Henry Hemmingway, surgeon, Dewsbury: 'When children are working where carbonic acid gas prevails, they are rendered more liable to affections of the brain and lungs. This acid prevents the blood from its proper decarbonization as it passes from the heart to the lungs. It does not get properly quit of the carbon.'—_Symons, Evidence_, No. 221; App. pt. i. p. 282, 1. 38. "Mr. Uriah Bradbury, surgeon, Mirfield: 'They suffer from asthma.'—Ibid. No. 199, p. 278, 1. 58.

"Joseph Barker, collier, aged forty-three, Windybank Pit: 'I have a wife and two children; one of them is twenty-two years old; he is mashed up, (that is, he is asthmatical,) he has been as good a worker as ever worked in a skin.'—_Scriven, Evidence_, No. 14; App. pt. ii. p. 104, 1. 60. "Mr. George Canney, surgeon, Bishop Aukland: 'Do the children suffer from early employment in the pits?' Yes, seven and eight is a very early age, and the constitution must suffer in consequence. It is injurious to be kept in one position so long, and in the dark. They go to bed when they come home, and enjoy very little air. I think there is more than the usual proportion of pulmonary complaints.'—_Mitchell, Evidence_, No. 97; App. pt. i. p. 154, 1. 2. "Mr. Headlam, physician, Newcastle: 'Diseases of respiration are more common among pit-men than among others, distinctly referable to the air in which they work.
