An Investigation into the Nature of Black Phthisis or Ulceration Induced by Carbonaceous Accumulation in the Lungs of Coal Miners

A vivid portrait of nineteenth‑century medicine unfolds as a physician details the mysterious “black phthisis” that haunts coal miners. Drawing on courtroom‑like presentations to Edinburgh’s Medico‑Chirurgical Society, the work explains how inhaled carbon particles from lamps, gunpowder smoke and poor ventilation settle in the lungs, producing a relentless cough, dark sputum and a slow, wasting decline. The author weaves together careful autopsy findings, striking illustrations of excavated lung tissue, and early debates among leading doctors about the disease’s relationship to tuberculosis.

Beyond the grim statistics, the narrative captures the human side of a harsh profession: youthful laborers whose vigor is quickly eroded by an invisible, blackened enemy. Listeners will hear the urgency of a physician striving to understand a new pathology, the clash of ideas among peers, and the hopeful promise that careful observation might one day spare future generations from the same fate. This historical investigation offers both scientific intrigue and a poignant glimpse into the lives of those who toiled underground.
