Phosgene still plays an important role as a toxic substance in the chemical industry. Thiess (1968) recently reported observations on numerous cases of phosgene poisoning. A serious difficulty in the clinical handling of phosgene poisoning cases is a relatively long latent period, up to 12 hours, with no obvious signs of severity. At about 12 hours heavy lung edema appears suddenly, however changes can be seen in routine X-rays taken after only a few hours' exposure (Diller et al., 1969). This study was undertaken to correlate these early changes seen by the roengenologist with morphological alterations in the lungs seen in the'light and electron microscopes.Forty-two adult male and female Beagle dogs were selected for these exposure experiments. Treated animals were exposed to 94.5-107-5 ppm phosgene for 10 min. in a 15 m3 chamber. Roentgenograms were made of the thorax of each animal before and after exposure, up to 24 hrs.

"Die Erfindung von Anilin und anderen synthetischen Farbstoffen in der zweiten Hälfte des neunzehnten Jahrhunderts ist der Beginn einer neuen Epoche. Die von der noch jungen chemischen Industrie produzierten neuen Farben sind nicht nur leuchtender als die meisten der traditionellen Farbstoffe, sondern auch viel billiger. Sie verändern das Aussehen von Frauen auf den Straßen der modernen Stadt. Unter den ersten Medien, die diese Revolution bemerken und dokumentieren, sind Modezeitschriften, realistische Romane und impressionistische Gemälde. Der Beitrag zeigt, dass die strahlenden Farben der neuen Palette der impressionistischen Maler ein direkter Effekt der chemischen Industrie sind. </br></br>The invention of aniline and other synthetic dyes in the second half of the nineteenth century is the beginning of a new epoch. The new colors produced by the fledgling chemical industry are not only brighter than most of the traditional dyestuffs, but also much cheaper. They change the appearance of women on the streets of the modern city. Among the first media to notice and document this revolution are fashion magazines, realist novels, and Impressionist paintings. I argue that the bright colors on the new palette of Impressionist painters are a direct effect of the chemical industry. "
