Abstract
I trust that the following case of pneumato-thorax, with the experiments made to illustrate it, will not prove un­deserving of the attention of the Royal Society, which, from its commencement, has warmly encouraged physiological inquiries, and every investigation directed to the improvement of medical science. Abraham Iredill, of the 7th regiment of Foot, aged 30, was admitted into the General Military Hospital at Fort Pitt, Chatham, on the 15th of January last, labouring under phthisis pulmonalis, and invalided on account of it.
