["The father of this lad and his brother fully corroborate this statement, and the father says the doctor told him that if he (the boy) had not been kept in the pit, he might have been, perhaps, saved. This boy never had any thing the matter with him before he went down into the pit."—Leifchild, Evidences, Nos. 156, 169, 270, 83, 110, 142, 143, 374, 194, 364, 135, 100, 101; App. pt. i. p. 582 et seq. See also the statement of witnesses, Nos. 315, 327, 351, 359, 360, 361, 362, 363, 365, 377, 381, 382, 384, 403, 434, 454, 455, 457, 464, 465, 466.]
Similar statements are made by all classes of witnesses in some other districts. Thus, in Shropshire:—
"A surgeon who did not wish his name to be published: 'They are subject to hypertrophy of the heart, no doubt laying the foundation of such disease at the early age of from eight to thirteen years.'—Mitchell, Evidence, No. 45; App. pt. i. p. 81, 1. 16.
"Mr. Michael Thomas Sadler, surgeon, Barnsley: 'I have found diseases of the heart in adult colliers, which it struck me arose from violent exertion. I know of no trade about here where the work is harder.'—Symons, Evidence, No. 139; App. pt. i. p. 261, 1. 36.
"Mr. Pearson, surgeon to the dispensary, Wigan: 'They are very subject to diseases of the heart.'—Kennedy, Report, 1. 304; App. pt. ii. p. 189.
"Dr. William Thompson, Edinburgh: 'Workers in coal-mines are exceedingly liable to suffer from irregular action, and ultimately organic diseases of the heart.'—Franks, Evidence, App. pt. i. p. 409.
"Scott Alison, M. D., East Lothian: 'I found diseases of the heart very common among colliers at all ages, from boyhood up to old age. The most common of them were inflammation of that organ, and of its covering, the pericardium, simple enlargement or hypertrophy, contraction of the auriculo-ventricular communications, and of the commencement of the aorta. These symptoms were well marked, attended for the most part with increase of the heart's action, the force of its contraction being sensibly augmented, and, in many cases, especially those of hypertrophy, much and preternaturally extended over the chest.'—Ibid. p. 417.
"Mr. Thomas Batten, surgeon, Coleford: 'A boy about thirteen years of age, in the Parkend Pits, died of hæmorrhagia purpurea, (a suffusion of blood under the cuticle,) brought on by too much exertion of the muscles and whole frame.'—Waring, Evidence, No. 36; App. pt. ii. p. 24, 1. 21.
To this list of diseases arising from great muscular exertion, must be added rupture:—
"Dr. Farell, Sheffield: 'Many of them are ruptured; nor is this by any means uncommon among lads—arising, in all probability, from over-exertion.'—Symons, Evidence, No. 47, App. pt. i. p. 286, 1. 2.
